Peri the ant walks the perimeter and doesn't enter the inside area.

"Peri" (french accent) the ant,

walks the perimeter.
Remember we don't want ants inside the house!

Math is fun and even better with food!

We used Cheez It's

to make rectangles...

This is a 4 x 4 rectangle.

If "Peri" the ant,

walks the perimeter, Peri will pass 16 sides (edges).

The Perimeter is 16.

The "Area" inside.... where we don't want ants is also 16 in this 4x4 shape.

This is a 2x2 rectangle 

If Peri the ant walks the perimeter, Peri will pass 8 sides (edges).

The Perimeter is 8.

The Area inside... where we don't want ants is 4.

We had such fun and learned a lot!
