A delightful way to review these 11 2-D shapes: circle, oval, triangle, rectangle, square, pentagon, hexagon, octagon, heart, star and crescent.
Helps reinforce colors and color words as well. Remind students that these are two-dimensional shapes and lie in a plane or "flat."
Put them on the wall as a border, or run off a set for your students and have them write the shape word and then trace and color the shape.
You can also laminate them, cut them up and make them into puzzles. Students match the word to its shape.
Pass them out to students and give spatial directions: "Put your shape over, under, between, behind, beside, left-right, etc."
