We have fallen in love with Magna-Tiles at our house. The boys have been playing with them daily for hours on end. I decided to enhance J's play with them one day by adding a mirror to explore symmetry.
I set up a star shape with the Magna-Tiles as an invitation. His first reaction was, "Oh it's a star! Cool!"
Simple Math Activity for Kids: Exploring Symmetry with Magna-Tiles
So J started putting some of different Magna-Tiles next to the mirror. He then leaned the mirror back and forth to see how the reflections changed.
Then in typical J fashion, he started creating numbers out of the Magna-Tiles. Here he is with the number two (and its reflection as the number five). J was curious about why the two turned into a five in the mirror's reflection.
J continued to make more numbers, such as the number seven pictured below.
This house or camel shaped design is actually the number 10.
It's amazing how J can turn literally everything he sees and plays with into numbers! What a kid!
