My four-year-old and I love exploring math concepts together. Lately, we've been learning about area and perimeter.
For this activity, we talked about how area is the space inside the bat shape and perimeter is the distance around the bat (or its outline).
We decided to measure the area and perimeter of the bat with buttons, one of my son's favorite crafting materials.
The buttons weren't going to give us a perfect measurement of perimeter and area--but there's no need to be too precise with a four-year-old! I just wanted him to understand the basic concepts.
