Cut It Out

This resource also includes:

Explore the mathematics of the paper snowflake! During the five lessons progressing in complexity from K through 12, pupils use spatial geometry to make predictions. Scholars consider a folded piece of paper with shapes cut out. They predict the shape of the cut after it is unfolded, or if it is already unfolded, how the shapes could have been made. As the lessons progress, the images become more complex and require deeper thinking.
