• Wind-Up Flashlight

  

  Ambessa

  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.

  For kids aged 8 years and up.

• Knight School

  

  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

  Particula also offers a Harry Potter-themed GoChess Mini Board ($350) which appears in my best smart chess boards guide.

• 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.

• 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.

• Marble Puzzle

  Kids love marble runs, and ThinkFun combines the joy of dropping marbles with a clever logic puzzle design in Gravity Maze. There are 60 challenge cards ranging in difficulty, and you must figure out how to place the available pieces to build a 3D maze that guides the marble to your target tower.

• 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 $23 for 60 pieces. —Adrienne So

• Robo Fun

  

  Robotical

  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.

• Construction Capers

  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.

• Early Engineering

  National Geographic

  4-Cylinder Engine Building Kit

  You can build a four-cylinder engine with this 175-piece kit. It’s fun to assemble, but there are lots of fiddly pieces (tiny screws and springs), so younger kids may need supervision. Once built, simply insert three AA batteries (not included), push the button, and it comes to life, with moving pistons, valves, gears, and light-up LEDs to help kids understand how engines work. The instruction booklet also includes a brief potted history.

• A Twist on a Classic

  

  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

• Sand Castles

  

  Kinetic Sand

  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.

• 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 all educational STEM toys aim for but many fall short of. Dash has lived with us for several years now and of all the coding robots I’ve tried, it remains my favorite. 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.
