Brick Mates – Stack By Numbers – Rocket Ship – STEM Toy For Kids 5+

STEM Learning

Brick Mates® puzzles and activity toys offer an introduction to early STEM learning through brain-building play.



Brick Mates® inspire curiosity and challenge Toddlers through 9-year-olds to explore, experiment, observe, question, compare, predict, try and share discoveries. Brick Mates@ provide both 2D and 3D context that helps them to make sense of the world as they figure out and apply what they are learning to more advanced play.



Early engineering doesn’t involve screen time. It starts with putting things together, like blocks, connecting bricks or puzzles, shape sorting and figuring out how things work. Brick Mates® pieces fit together and they’re compatible with other brick and brick playsets on the market. Brick Mates® help children develop spatial skills while improving fine motor skills.



Brick Mates® is a wonderful intro to technology. Children discover that it’s more efficient and more fun to pop-up all of the Lock and Learn puzzle pieces at once by pushing on the tabs.  Or, with Stack By Numbers, kids learn they can create more detailed & realistic art by placing the included stickers on top of the bricks.



Kids learn by doing, which is why Brick Mates® are perfect toys for teaching math and reinforcing math concepts with kinesthetic learning. It’s easier for early learners to understand “2” when they can hold a three dimensional number “2” in their hand, fit it into a “2” space on the baseboard and count the two animals on the Lock N Learn puzzle. 

Toys Should Be Fun AND Educational


What People Are Saying…

Parents, Teachers & Doctors alike love Brick Mates and so do the little ones!

    What a delight it was to watch a number of children play with Brick Mates!  No screens, no sequins and no television characters.  But more importantly, these toys naturally engage a number of cognitive areas at once:  visuospatial functioning, executive functioning (planning and organization) as well as higher order categorization and even early language skills.  Brick mates, like Legos, move seamlessly from more organized, step-by-step driven tasks to free-form creative play.  These are brain-building toys that can be used independently, cooperatively or even therapeutically.  I can’t say enough about them, they’re magic.

    We have BrickMates Stack By Numbers and Lock and Learn at my Daycare and the kids LOVE them!  Our kids often ask to take them home to play with them and I was told by a few parents that their child had asked for them. The best part about each puzzle is the children are learning patience, math skills, abstract and critical thinking throughout their "play time". The teachers are very happy that it's not another project to clean up since the blocks snap into place on the board. Everyone is happy and that is hard to achieve these days!

Science is a way of thinking.  Technology is a way of doing.  Engineering is a way of solving.  Math is a way of measuring.
