Help your student become a(n) Shape Recognizer—Circles, Squares, and Triangles

Activities and discussions invite children to name shapes that are common in the culture, circles and squares, and triangles. Include shapes that are less typical--that are turned different ways, as well as "long, skinny" triangles and so forth as soon as possible to give children rich, varied mental images of shapes.
