“I think the universe is pure geometry -
basically, a beautiful shape twisting around and dancing over space-time.”
~ physicist Antony Garrett Lisi
I’ve already covered counting and number sense and multiplication and fractions. This month I’m wrapping up my math series with geometry. Here are all my favorite fun and easy resources about shapes and angles!
(Just a reminder - I am never paid to mention any of these resources; there are no affiliate links.)
Geometry Math Videos
From PBS
Peg + Cat solve really big problems (often of their own making) with catchy tunes and fun math! The 11-minute episodes are targeted to preschoolers. Here’s a clip of Peg and Cat searching for 3 golden pyramids, but being given 3 golden cubes instead.
Full episodes are available on the PBS Kids website or PBS Kids Video app (for iOS or Android). (Click the three vertical lines on the right to see which full episodes are available. A new batch of full episodes get rotated in every week.) There’s also a ton of Peg + Cat activities and games on the PBS website!
Odd Squad
From PBS
Another delightfully silly math-themed PBS show! This one is targeted for early elementary kids. I love how committed the kid actors are to hamming up their roles as secret agents, investigating odd occurrences around the world. In this clip, the agents must figure out a way to make a cube from other 3-D shapes, so they can repair the woosh-you-back-in-timeinator (of course).
Again, full episodes are available on the PBS Kids website or PBS Kids Video app (for iOS or Android), and my kids have enjoyed a bunch of the Odd Squad games on the PBS website.
From The Magic School Bus Rides Again (Netflix)
Ralphie needs to help his family’s circus show go on! Can the kids use geometry to setup the trapeze, so the trapeze artists don’t fly into each other?
Geometry Math Books

“Round are tortillas and tacos, too.
Round is a pot of abuela’s stew.
I can name more round things. Can you?”
Younger children can point out the shapes mentioned in the rhymes, and older children will love searching the illustrations for even more shapes. The illustrations incorporate Latino culture, and the glossary translates many of the Spanish words.
The same author also wrote “Round is a Mooncake: A Book of Shapes”, illustrated by Grace Lin, with sweet scenes from an Asian American family’s daily life.
By Suzanne Morris
This is not your typical shapes book, as you can see from the title! Can Trapezoid audition for the shapes play? Is he even a shape, or is he secretly a dinosaur? Trapezoid tries to act like the other shapes, but eventually his unique shape is what saves the play.

Food is an excellent vehicle for teaching math concepts, even infinity! Siblings X and Y are dreaming of infinite pies. So their Aunt Z shows them that if they cut a pie in half over and over again, they will have an infinite number of pieces of pie. And that a round pie is a shape with infinite corners. And that a fractal pie crust would have infinite corners too! My kids asked to reread this one multiple times! This is the first picture book from the same author who wrote the bestseller “How to bake ℼ: An Edible Exploration of the Mathematics of Mathematics.”
Geometry Math Activities
Go on a shape hunt!
What shapes will you find in your play room? Your house? Your backyard? You can look for 2D shapes or 3D shapes, or both! You probably won’t have to look far - I spot triangular prisms and rectangular prisms in this train set here.
From PBS Kids
This free printable puzzle gets kids seeing the possibilities of rearranging simple shapes!
Highlights Shapes app
This app is a very intuitive first app for toddlers and preschoolers. They drag shapes over to corresponding holes, learning the names of shapes and colors and working on their fine motor skills at the same time!
For years this was the miracle app on my phone when I just needed a fidgety kid to sit in the grocery cart for 5 more minutes! I’m still a little sad that my kiddos have outgrown this one.
Geometry Math Podcast
from the Ear Snacks podcast
This goofy podcast always makes a long drive a little more fun for my kiddos! Andrew & Polly are award-winning musicians, so they know how to make podcasts that are a joy to listen to. Listen along as they play a game making animals from shapes and hunt for shapes in other fun places!
I hope I’ve given you some fun angles to teaching geometry!
Next month I’ll wrap up the summer with STEM resources on the Sun and solar power. Sign up here with your email, so you never miss a post!
Until then, have fun lighting sparks of curiosity!
