This anchor chart is 2 sides, one side has properties of angles and general vocabulary about polygons. The other side has all the properties of Parallelograms, rectangles, rhombus, squares, kites, and isosceles trapezoids. I tend to keep a class set around in case students need it while learning.
The third page can be used as a student copy to keep in an interactive notebook so as you go through the unit, students can mark on this and they will have something to carry with them throughout the unit. They also have boxed to put notes for themselves if needed.
