Studies show overwhelmingly that giving building blocks to children helps them learn special skills and grow smarter faster. Different block companies are focused on different goals though. So which blocks would be the best for your children?


This product actually started as a Kickstarter project. It’s aimed specifically at young girls to help them get excited about engineering. Currently there world’s engineers are nearly 90% male. That’s why the motto of Goldieblox is “Disrupting the pink aisle.” The goal is to even the score and change the idea that building blocks are only toys for boys. Each set helps children learn a different engineering concept, and they all come with little animal figurines.


  • GoldieBlox and the Spinning Machine-This one costs about thirty dollars  and it’s aimed at ages 4 to 9. It teaches about belt drives with a book, as well as 16 design ideas. It comes with 1 pegboard, 10 axles, 5 blocks, and so on.
  • Goldieblox and the Parade Float-This set is around 20 dollars and it teaches the wheel & axle concept. It has a storybook, wheels, blocks, different types of axles, a ribbon, bands, spacers, and animal figurines.
  • Blox & Bits Expansion Pack


  • Videos Featuring Possible Block Inventions-The site is full of videos showing inventions that real young girls have made, which should give you an idea for what’s possible for your kid.
  • Shirt, Hoodies and Onesies
  • Goldieblox based on Real Research- This includes interviews with neuroscientists, teachers, STEMP experts and of course the girls themselves. Goldieblox is based on the idea that girls have good verbal skills and don’t want to just build things, they want to connect them to stories. This is the reason for all the animals and characters in addition to the blocks.

Goldie Blox sets like this Parade Float one emphasize characters along with the blocks.

K’Nex Industries

K’NEX is a building block company that’s aimed at older audiences of both genders. There are categories for K’nexpert going from 5 all the way up to 12. K’NEX makes it easy to build things with moving parts as well, like roller coasters, cranes, and so on. There’s a lot more complexity here than with Goldieblox. The price is usually a bit higher though, with sets going up to $60 or more, though you do get a lot more with these sets.

Head to Head


Girl-Friendly- Goldie Blox is focused especially on girls, adding stories to the creations rather than just straight up building like K’Nex. It could also appeal more to younger audiences since the concepts are often much simpler.

Universal Engineer- K'NEX can be used by girls and boys alike, and the complexity is such that it will appeal to older audiences. The concepts are often a lot more grown up too, with more than just spinning levers and ribbons like in Goldieblox.

Glodie Blox shows off many of the creations of young girls, like in this video.

This video demonstrates how K'NEX is not just for kids since you can create some truly complicated creations.
