After students have explored properties of parallelograms, I had them investigate a square, rhombus, isosceles trapezoid and kite.
Students did a Jigsaw in this activity. I gave each student a color card (one of four colors). They grouped with their like colors and investigated an assigned shape. They then regroup (one card of each color) and share their discoveries with their groups. The members of the group fill in the other 3 sections of the handout.
