So I got these for my son for his birthday after hearing about it in a local homeschool group. Now he’s only 3, but there’s ton’s of things he can learn from these! Some examples include colors, sorting/matching, counting to ten, counting to 100, skip counting, basic addition/subtraction/multiplication/division, fractions and more! They work as small building blocks too and each side has a different shape on it. You can you the building block feature to build the shape of a letter or number and you can make some 3D shapes as well. Right now my son loves having me put them together and he loves to break them apart, which is practicing fine motor skills and hand strength.
