What children learn in Level 56

Welcome to Shape Park! A circle is round. It has no straight sides and no corners.
A triangle has 3 sides and 3 corners. Triangles can be tall, wide, or turned. They're all triangles!
A square has 4 sides, all the same length. Turn it on its corner, and it's still a square.
A rectangle has 4 sides too: two long sides and two short sides. Lying down or standing up, it's a rectangle.
Try it with a grown-up! Look around your room. Can you find a circle, a triangle, a square, and a rectangle?
