Free Math 2D Shapes Mini-Book. This book includes the following shapes: circle, star, triangle, square, oval, rectangle, rhombus, heart, hexagon, octagon, trapezoid. On each page students draw a real world example of the shape. For example, on the star page, I have my students draw a flag with a few stars on it. It’s great fun and provides good geometry reinforcement after learning a little about each shape. There are 14 pages in the book. You can use all or some of the pages in your book.
