Rhombi

Foldable

1. Take out a piece of notebook paper and make a hot dog fold over from the right side over to the pink line.

Foldable

2. Now, divide the right hand section into 5 sections by drawing 4 evenly spaced lines.

3. Use scissors to cut along your drawn line, but ONLY to the crease!

The fold crease
