Second graders name flat shapes by what they see: how many sides, how many corners and whether the sides are straight or curved. A triangle has three sides, a pentagon five, a hexagon six, and a circle has no straight sides at all. This worksheet shows eight shapes, one in each cell, with three names beside each, and your child circles the right name.
The wrong names are other shapes, never a name that also fits, so there is only one answer. Ask your child to count the sides and corners of each shape out loud before circling. Counting along the edge with a finger is a good way to avoid skipping a side. Point out that a square and a rectangle both have four sides and four square corners.
