Inchimals by Fat Brain Toys

Inchimals turns numbers into something children can build, compare, and explore.

This set includes twelve wooden animal blocks, each exactly one inch taller than the last—from a 1-inch bee to a 12-inch giraffe. Marked with inch measurements, numerals, and dot patterns, the blocks help children connect quantity, number symbols, and measurement in a hands-on way.

The mathematical relationships are built right into the animals. Stack the 1-inch bee on top of the 2-inch frog, and together they match the height of the 3-inch penguin. Children quickly discover addition, subtraction, comparison, and number patterns simply by manipulating the blocks.

The updated edition includes two wipe-clean puzzle books and markers that extend learning beyond free play. Younger children practice sorting, sequencing, counting, comparing, and learning math vocabulary. As skills grow, the puzzles introduce arithmetic, problem-solving, equations, and early algebraic thinking.

One of the strengths of Inchimals is its longevity. A preschooler may spend time stacking animals and exploring size differences, while an older child uses the same set to investigate measurement, number relationships, and mathematical reasoning.

Parents appreciate that the blocks encourage independent discovery. Instead of being told that numbers relate to one another, children can see and test those relationships for themselves.

Whether your child is learning to count, exploring addition, or beginning to recognize algebraic patterns, Inchimals provides a durable, reusable way to make mathematical concepts meaningful and memorable.

    Was a good addition to our kit

    Sara W.

    Was fun to add into our breaks for learning fun. Gave our daughter math visuals she could relate to. She loves animals.

    Fun math

    Maria P.

    My 4yo likes to add and subtract in his head. Using the inchimals we are able to relate the math to real things, and better understand how big an inch is. I do the writing in the workbook, as we manipulate the inchimals together. They are fun to play with too. We enjoy lining them all up and adding the total distance across the room.

    Love This!!

    Sheri

    This is a very high quality product. It stands up against rough use. It is a great tool for helping review math skills that makes learning more fun. Would highly recommend this to others.

    So far holds interest

    Anna H.

    So far my 6yo has been independent with these and seems to enjoy the freedom to do on her own (or bossing the littlensiblings to give her this or that!). The 2 and 4yos also love them. Bonus discovery: the sticks themselves wipe off easily when the littles found the dry erase marker. Happy to know it is pretty indestructible when trying to work with all age ranges in one room.

    One of our best learning purchases!

    Kristy W.

    My 5 year old loves playing with these and doesn't feel like it is school work. I wish I had got them a year ago! We use them for both a manipulative for doing math problems, as a toy, and also as a fun extra using the workbook that came with the set.

    Inchimals are a hit!

    Rachel P.

    This is such a cute way to teach introductory math. My kids are always asking to play with this, and it has introduced my 4 year old to mathematical symbols and measurement. Each animal has segments the kids can count, dots for counting, and the actual number. It has helped reinforce her number recognition and she loves making up stories about the animal characters.

    Inchimals

    Sarah S.

    Ordered this as an activity for my son to use. He has really enjoyed stacking them up, comparing them, and solving the problems. Works as great as I hoped! What I didn’t expect was how much his little sister would love them! She gets them off the shelf to play with them all the time. She doesn’t solve the problems yet, but she sure does like to organize them by size. AND she is practicing tracing numbers all the time because she wants to use the book like her big brother. Overall I’m really pleased with the purchase.
