This slide show teaches the Virginia Standards 1.12 and 1.13. We cover the plane shapes: circle, square, triangle, and rectangle. We also teach sides, vertices (corners), and right angles.
When you click on the page, it will count the number of sides, vertices, and right angles. Also on the question pages, when you click on the right one you get a surprise and when you click on the wrong ones you will know it was wrong.
