  We’re in love with this screen-free speaker for kids. The cute wooden design includes a circular sound stage where you can insert a cartridge and pop characters on top to change the audio it plays. This basic functionality allows for a clever variety of add-on packs, from stories about quirky characters in the Groblies ($20) to a cooking game called Bernard’s Kitchen ($20) with different ingredients. My favorite is the Little Maestro set ($20) featuring players in an orchestra covering Mozart, Vivaldi, Beethoven, and Bach. The stereo speakers are quite good, it has a headphone port, and the Qubitunes can be recharged via USB-C for up to six hours of play. My wife has this in the reward area of her classroom, and it’s the most popular option with 7 and 8-year-olds. —Simon Hill

  DIY Kinetic Flashlight

  Kids can build this wind-up flashlight themselves and learn all about electronic components and kinetic energy in the process. The thoughtful design includes 10 separate parts, and there are 16 steps to follow to assemble it. No batteries are required, and the kit is designed to be easy to disassemble and use again, making it perfect for a classroom setting. Our testers were delighted that simply winding the completed flashlight brought it to life (three minutes of winding provides 30 minutes of light). For every kit purchased, the maker, Ambessa, donates one to a refugee child out of school.—Simon Hill

  Construction kits are compelling no matter your age, and my entire family found Clixo’s colorful, versatile, snap-together magnetic pieces irresistible. You can build three-dimensional shapes from these flexible pieces by connecting the magnetic ends and bending them the way you want (my youngest made a cat, my teen made a crown). These durable and washable pieces stack neatly to pack away. We love that you don’t need a flat surface to build because it means you can play with these kits anywhere. If you prefer a themed pack, we also liked the Mars Rover Pack ($50) and the Ocean Creatures Pack ($35), and both sets feature glow-in-the-dark pieces. —Simon Hill

  I have been struggling for a few years to get my now 7- and 9-year-old interested in chess, and the GoChess Mini works wonderfully. This lightweight, portable board is beautiful to use—the pieces have a nice matte finish and are pleasingly weighty. Once you charge the Bluetooth-enabled board and connect it to the app, you can either play against remote players, against yourself, or get AI-enabled assistance to help guide your moves. You can scale the amount of assistance, whether it’s a little or a lot, and different-colored lights show you the advisability of different moves as you pick up each piece. One evening of charging results in weeks of playtime; my kids will play for hours and discuss each move as they go. It’s great.—Adrienne So

• Marble-Powered Computer

  Turing Tumble is a wonderful way to teach kids coding fundamentals. It combines the simple pleasure of marble runs with a beautifully illustrated sci-fi comic book packed with challenging puzzles. The board resembles a pachinko game, and you have to slot in different pieces to divert the blue and red balls and get the required pattern at the bottom. My 9-year-old spent hours working through the puzzles, reconfiguring this marble-powered computer. As the challenges grew tougher, the whole family joined in to find solutions. Well-designed, satisfying, and rewarding, this is a good pick for most kids. —Simon Hill

  For kids aged 8 years and up.

• Lego Robots

  Lego Education's Spike Prime building set is a complete DIY robot-building classroom in a box. Literally. Prior to the abrupt rise in distance learning several years ago, Lego marketed this primarily to schools. It comes with its own lesson plans, but don't let the seriousness fool you—my kids love this set and went from never having used it to programming their own robots (using the drag-and-drop Scratch programming language) in a couple of afternoons.

  Lego keeps updating Spike Prime too. Recently it released a new series of plans for bots that track exercise and help kids learn about motion and energy transfer. —Scott Gilbertson

  For kids aged 11 years and up.

• Coding Ball

  The Sphero Edu app is packed with computer science lessons and activities for different age groups. Bolt has an 8 x 8 LED board on top, various sensors inside (compass, light sensor, gyroscope, accelerometer), and supports infrared communication. My wife is a teacher and uses this in the classroom to teach basic coding skills, giving students challenges like navigating a maze. She says many kids grasp the concepts much faster than they might with a book or screen, because they can see the Bolt moving in physical space. —Simon Hill

  For kids aged 9 years and up.

• Endless Building Fun

  The return on investment with Magna-Tiles staggers me. It's been years, and at 6 and 8 years old, my children can still occupy themselves with these for hours. Translucent Magna-Tiles click together to form both two-dimensional shapes and three-dimensional objects. Younger kids can make a house with a backyard and fences, or ice cream cones. With an older kid, the sky is the limit—or, rather, your credit card is, since there are wheelbarrows full of expansion sets you can buy. My daughter can currently build a full village in an afternoon for her stuffed animals.

  If these are too pricey, there are alternatives that work just as well, like Picasso Tiles, which are $28 for 60 pieces. —Adrienne So

  For kids aged 3 years and up.

• Underwater Vistas

  Chronicle Books' gorgeous picture book tells the story of Ken Nedimyer, an environmental scientist, live rock farmer, and fish collector who founded the Coral Restoration Foundation.

  The book weaves together details of Nedimyer's biography with facts about coral reefs—I did not know that corals spawn like fish do—and luminous underwater landscapes and depictions of scuba diving. It makes environmental preservation and following your passions look both doable and fun. —Adrienne So

  For kids aged 5 years and up.

• Robo Fun

  Marty the Robot V2

  Combining coding with robotics can be a great way of engaging kids, and Marty the Robot V2 is an irresistibly charming biped with nine servo motors inside that enable him to walk, kick, wave, sidestep, and even waggle his eyebrows. There’s a customized microcontroller inside, various sensors, Bluetooth connectivity, and a speaker, so there’s plenty of potential for kids to code various routines and an extensive knowledge base with lessons and tutorials. Robotical has designed Marty for kids of all ages, so at the basic level, you can use color cards (green to move forward, for example) to control him. Older kids can use Scratch, a simplified coding program with drag-and-drop blocks on a connected Android or iOS device, and when they’re ready to advance, they can move on to Python. Marty is cute and fun but very expensive, though it’s mainly geared toward use in schools, and there are lots of good resources for educators.—Simon Hill

  Classic Magnetic Building Set

  My entire household found this magnetic construction set irresistible, and there has been a new 3D structure on the coffee table every morning. The kit comprises glow-in-the-dark magnetic rods (crafted from recycled plastic), steel spheres, and plastic bases in different shapes. You also get storage boxes to put everything away in. There’s a guide in the box with a few suggested structures, but creating your own is a big part of the appeal. There are sets of various sizes. —Simon Hill

  For kids aged 3 years and up.

• Color Chemistry

  Crayola

  Color Chemistry Set

  Everyone who has come across a Crayola crayon has probably melted one, whether accidentally or on purpose. Crayola's Color Chemistry set includes enough brightly colored Crayola ingredients for 16 activities out of the box, and up to 50 with common household ingredients. Exploding volcanoes and colorful quicksand are just a few of the eye-catching experiments that you can look forward to trying. —Adrienne So

  No one needs a Bluetooth-enabled Rubik's Cube, but once you get your hands on a GoCube you probably won't be able to put it down. Smart sensors inside the beautiful, glowing cube connect to a companion app on your phone and sense where each block is positioned. You can learn algorithms and strategies that will help you get your solve-time down. And if you give everyone you know a GoCube, you can also stage live competitions with friends and family! —Adrienne So

  For kids aged 8 years and up.

• Sand Castles

  My kids love this moldable sand and have happily spent countless hours over the years making tabletop structures. It behaves like wet sand and never dries out, so you can shape it with your hands or use tools and molds to make castles. It comes in many colors and clumps together easily but doesn’t stick to your hands or surfaces. While it’s generally easy to clean up, it’s a good idea to confine play to a tray or table and supervise your kids, or you may end up picking tiny bits of pink sand out of your carpet. —Simon Hill

  For kids aged 3 years and up.

• Remote-Controlled Robot

  This super-cute robot looks like it rolled straight out of a Pixar movie. With a big, expressive eye atop three balls, it zips around with real personality, which helps it successfully combine play and learning in a way that every STEM toy aims for but many fall short of. Dash has lived with us for several years now. It’s a durable toy that works on a simple level like a remote-controlled car, but it also ties in with various apps to play games, solve puzzles, and create programs. Lego connectors for Dash’s head add to the creative possibilities. Wonder Workshop also offers some optional accessories. —Simon Hill

  For kids aged 6 years and up.

• Rock On

  Learning how to play a musical instrument is associated with many positive outcomes for kids, from improving concentration, dealing with frustration, better hand-eye coordination, and sensory development. This is with the caveat that my children already know how to play the piano and violin, but the Loog mini guitar is one of the easiest and fastest ways I’ve ever seen them pick up a musical instrument. It feels like a real guitar, but smaller, and the three-stringed version that we have is manageable for a 7-year-old’s hands. The Loog app is fun and easy to follow—my son tuned it himself the first time he picked it up!—and the games that teach you about frets and strumming are surprisingly engaging. They’ll be shredding in no time.—Adrienne So

  Tacto uses physical pieces to turn your iPad, Android, or Fire tablet into a game board. Tacto Chess teaches the basics, from how the pieces move to strategies for victory. The animated app boasts friendly voice acting and stories to draw kids in. There are also chess puzzles to solve and a move predictor, and your child can play against AI or another person. Both my kids (9 and 12) have enjoyed some time with this, so it works well for different ages and abilities, but it was a little fiddly to get the pieces to register on the iPad Mini, so a larger tablet is advisable. Other Tacto packs cover dinosaurs, classic board games, coding, and electronics. —Simon Hill

  For kids aged 6 years and up.

• Coding Car

  

  Courtesy of Qubs

  Teaching basic coding concepts to young kids is a challenge. To do it without a screen is even tougher. But QUBS has come up with an elegant solution. These beech wood blocks look like buildings, but each has a symbol relating to a command (turn left, turn right, U-turn, repeat the last command, stop, record path, play path). When kids put the magnetic top on the red car, it begins to drive. Using radio-frequency identification (RFID) technology, the car reads the commands on the blocks. There’s a lovely guidebook that includes stories and activities, but the best thing about this Montessori-inspired wooden toy is that kids can dive in and learn how it works through play. —Simon Hill

  Kindle Paperwhite Kids (2024, 12th Generation)

  No parent has ever complained that their child was reading too much. You might think that Amazon's Kindle Kids is a regular Kindle Paperwhite in disguise, but it includes a year's subscription to Amazon Kids+ (formerly FreeTime Unlimited), a two-year replacement guarantee, and, yes, a cute cover.

  Not only does Amazon Kids+ give your child access to more than a thousand kid-friendly books in both English and Spanish, as well as Audible titles, but I also found it easy to whitelist even more free titles (free books!) from my local library using Amazon's parent dashboard. You can also highlight or look up difficult words or add them to a Vocabulary Builder tool. Testing this Kindle is the first time I've gotten my 7-year-old interested in longer chapter books, so I'd give it a ringing endorsement based on that alone. —Adrienne So

  Let's Start Coding

  Ultimate Coding Kit

  Many STEM toys dumb down programming tasks, and that can limit their usefulness. The kits from Let’s Start Coding reject that approach, offering hands-on time with electronic components and challenging kids to dive straight in and create programs in C++. The Ultimate Kit includes 23 separate parts, including an LCD screen, speaker, LED strip, various sensors, and more. There are more than 100 projects to embark on, with example code that kids can tweak and helpful, if somewhat dry, walkthrough videos.

  My kids required some encouragement and supervision with this, and I think the suggested age of 8 years and up is low. Perhaps more important than age is a genuine interest in hardware and coding. But there’s satisfaction in successfully controlling hardware components. A Windows, Mac, or Chromebook desktop or laptop is required to use the free software. Younger kids may be better off starting with a smaller, more focused kit like Code Rocket ($60). —Simon Hill

  National Geographic

  Rock Tumbler

  The best toys are the ones that aren't toys at all. This year, my children became extremely interested in fossils and geology. We've been taking walks in the woods or at the beach, putting promising specimens in our pockets. We often keep the rock tumbler running for weeks (outside, because it's a little noisy), changing out the grit and watching as rough rubble eventually reveals itself as sparkly quartz or agate. If you're feeling ambitious, you can also throw in a rock guide and plan a rock-hunting trip. —Adrienne So

• Colorful Clay

  Part of exploring the world is feeling the world, digging in the dirt as it were, but if you don't have a yard or live near a park, you can bring some of that same spirit of exploration inside with polymer clay.

  This is the mold-and-bake clay you might have used growing up. It just has a fancy new name. The things your kids create might not always hold up, but that too is a learning process—after her doll's table fell apart several times, my daughter asked if I could reinforce the legs with wire. Other fun sculpting options include modeling clay ($7) and good old-fashioned Play-Doh ($22). —Scott Gilbertson

  Most kids love construction kits, and the OffBits combine special components with standard hardware bits you might have lying around the house, like nuts and screws. Each kit boasts a special assembly tool and a robot, creature, or vehicle to build. My daughter enjoyed putting the UnicornBit together, and kids are encouraged to get creative in their approach and adapt designs to suit them. The only roadblock we ran into was that some pieces were tough to connect, requiring some adult muscle, and others felt loose, but the end result was charming. OffBits offers various kits (mostly for kids ages 6 and up), but with small pieces and tricky assembly, we advise adult supervision. —Simon Hill

  Workman Publishing Company

  Paint by Stickers

  I know what you're thinking: Painting with stickers sounds kind of lame. But trust me, kids love these books. There's something about the balance of fun and meticulous concentration that draws children in. These are also a fun and mess-free activity for traveling with younger children. If your child isn't a dinosaur fan, there are plenty of other options, including unicorns, undersea animals, bugs, and more. —Adrienne So

  Nintendo

  Labo Cardboard Kits

  If you already have a Nintendo Switch, you must try Nintendo Labo. These clever kits, composed of corrugated cardboard sheets and stickers, must be assembled so you can play related games with your creations on the Switch console. Beyond the challenges and mini-games, you can dip into the software and learn how each kit works. You can even set up your own rules, reprogramming your creations in the Toy-Con Garage by dragging and dropping blocks to create simple inputs and outputs. We like the Vehicle Kit best, but there are several alternatives. It's worth noting that these kits are not designed for the Nintendo Switch 2, and some of them flat-out won't work. —Simon Hill

  Abacus Brands

  Bill Nye's VR Chem Lab

  It doesn’t really matter if your kids know Bill Nye the Science Guy, because this 23-piece kit is packed with scientific experiments and activities that are likely to suck them in. The multilayered learning includes a booklet with test tubes and various safe chemicals to test, but there’s also a cardboard VR headset (use your own phone) with short instructional videos from Bill Nye. Some experiments are more fun than others; just be prepared for lots of mess. Everything is well packaged, but it’s a shame the packets are not resealable. —Simon Hill

  For kids aged 8 years and up.

• Art and Design

  This quirky kit from South Korean designer Eunyoung is a marriage of modern art and mechanical construction. You can connect the various pieces in limitless ways with a simple pegboard, shapes, and assembly clips, add your own art, and animate your creations. If you want to dive deeper into STEM, the motor kit ($49) enables you to program your constructions using a micro:bit and the Sketch a Move add-on ($59) for older kids allows you to create dynamic abstract art. You can find a range of tutorials to help you get started on projects. —Simon Hill

  Science of Cooking: Bread & Butter

  We've tested many gift subscription kits, but my daughter declared this baking kit to be the most fun of all. We've talked about yeast, watched carbon dioxide fill up balloons ("We're eating fungi farts!"), talked about the different states of matter while making butter, kneaded dough, and finally, had cinnamon toast for a snack. It requires a lot of parental supervision over a lengthy period of time, but I also liked that she now has her own separate measuring cups and tools and can quit stealing mine. —Adrienne So

  Educational Insights

  Kanoodle Pyramid

  Can you fit these Tetris pieces into a three-dimensional puzzle board? My 11-year-old loved this logic puzzle, though she found the 2D puzzles too easy. Luckily, there are 100 3D puzzles that require spatial reasoning and problem-solving skills to beat. They get tougher as you progress, but never too hard. This puzzle kit is recommended for kids aged 7 and up, but some younger kids could have fun with it, too. Kanoodle also offers a bunch of other brain-teasing puzzles specifically for younger kids. —Simon Hill

  Sargent Art

  Tempera Paint Sticks

  Tempera paint sticks are like oversized crayons, but instead of wax, your kids smear tempera paint around. Don't worry, it dries quickly (in about a minute and a half), and it's easy to clean off most surfaces. It's all the fun of painting, but there are no brushes or other mess to clean when your kids are done. There are sets of all sizes. We started with this 12-piece set but have since expanded to a 32-color set ($28). —Scott Gilbertson

• Coding Cutie

  

  Courtesy of Ozobot

  It’s amazing how bleeps and bloops, colored LEDs, and cute animations lend personality to a tiny robot. The Ozobot Evo is like a mini R2D2 your kids can control. There are a couple of ways to program the Ozobot Evo. It follows black lines drawn on paper and changes the color of its lights to match the colors drawn. Blocks of varied colors also act as codes to trigger animations, change speed, or perform another action (a workbook explains). Ozobot is an easy, screen-free introduction to coding principles for younger kids. Older kids can try Ozobot Blockly, a typical drag-and-drop coding language that lets them build simple programs quickly.

  My 10-year-old enjoyed playing with this for a while, but I agree with our original review that the Ozobot Evo would work best in the classroom. Ozobot offers handy teaching resources, and the Evo makes for an engaging problem-solving activity for small groups. —Simon Hill

  NASA

  Astronaut Neapolitan Ice Cream Sandwich

  A funny thing about our jobs is that often, PR packages arrive unrequested. Such was the case with a package of official, NASA-sponsored Neapolitan ice cream sandwiches. (We also got mint chocolate chip and cookies and cream.) I hate to endorse this practice, but this was the perfect package to spark my 7- and 9-year-olds' interest in space and space travel. We quickly followed this up with real-life astronaut Clayton Anderson’s kids' book about 152 days aboard the International Space Station. Space is neat! But you have to learn math first.—Adrienne So

  Made from 12 magnetic shapes, this cube can be reconfigured in a surprising variety of ways. The exteriors are covered in holographic stickers that catch the light, and there’s a spinner accessory and a companion mobile app with building suggestions (though it’s not really necessary). This kit is fun for anyone to play around with and has proven a big hit with my wife’s current class of 7 and 8-year-olds. —Simon Hill
