Free 2D Shapes Worksheets for Kindergarten – Count Sides and Corners

These free printable 2D shapes worksheets help kindergarten and first grade children look closely at flat shapes and describe them with numbers. For each shape kids count how many straight sides it has and how many corners, and write the two numbers in the boxes. The shapes include triangle, square, rectangle, pentagon, hexagon, and circle, so children learn that a circle has no straight sides and no corners while a hexagon has six of each. Counting sides and corners is the first step in geometry and helps children tell shapes apart. The final page is an answer key. Just download, print, and count!
