Polygon Monster
Learners brainstorm different kinds of shapes. They then draw them on the paper and write the name of the shape on the back and then assemble the shapes to make a "monster". Students make up a survey about the monster including its name...
Curated OER
Strut Your Stuff
Students begin the lesson plan by identifying what a polygon is and hypothesizing how many struts (diagonals) it would take to make a polygon rigid. They watch a "Magic School Bus" episode then experiment with various shapes to make a...
