You’re probably familiar with tangram puzzles. They’re the puzzles that test one’s logic and spatial reasoning, making them a fantastic math exercise. And they’re super fun.

Here’s a quick way to turn lunch time into math play with tangrams. Now let’s eat some geometry!

You’ll Need

• jam
• rolling pin
• knife
• ruler (optional if you’re really good at estimating)

Directions

1. Roll out your pieces of bread using a rolling pin. You’ll want them nice and flat.
3. Cut the crusts so you have a 4 by 4 inch square.
4. Spread your jam on one slice. Lay the other on top.
5. Use the knife to cut the bread as pictured above.

Now challenge the kids to create pictures using the shapes from their tangram sandwich before they eat them.

Bonus Points

Have the kids identify the following polygon shapes while they’re playing:

• triangle
• square
• parallelogram
