What children learn in Level 69
- Shapes are named by how many sides they have. 3 sides make a triangle, even when they look different!
- 4 sides make a quadrilateral. Squares, rectangles, rhombuses, and trapezoids are all quadrilaterals.
- 5 sides make a pentagon. A house shape is a pentagon!
- 6 sides make a hexagon, like a honeycomb cell. Even a bumpy L shape with 6 sides is a hexagon!
- To name a shape, count its sides. It doesn't matter how big it is or which way it's turned.
