Flat Shapes

Name circles, half and quarter circles, triangles, squares, rectangles, and hexagons.

Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.

What children learn in Level 48

Flat shapes are everywhere! A circle is perfectly round. Cut it in half, and you get a half circle. Cut it in fourths, and you get a quarter circle.
A triangle has 3 straight sides. A rectangle has 4 straight sides and square corners.
A square is a special rectangle: all 4 sides are the same length. So every square is a rectangle too!
A hexagon has 6 straight sides, like a cell in a honeycomb.
Try it with a grown-up! Go on a shape hunt. Find a circle, a rectangle, and a triangle around your home.
