Quadrilaterals with Anglegs

I taught a lesson to a 4th grade class on quadrilaterals, using the anglegs. The students were in groups of 3-4. At first, each student had four anglegs of the same color, but each person in the group had a different color. We talked about the shapes they could make and what those shapes were called (square and rhombus). The students formulated rules for their squares and rhombi. We also discussed congruent and noncongruent. Then I had each student take their shape apart and pass two of their anglegs clockwise to the next person. Some students constructed parallelograms and some constructed kites. We discussed the similarities and differences. Next, I had the students who had created the kites change theirs to parallelograms. We compared rectangles and parallelograms and the students again formulated their set of rules. The students loved using these manipulatives!
