What children learn in Level 57
- Shapes have sides and corners. A side is a straight edge. A corner is where two sides meet.
- Your turn! Tap each corner of the triangle to count them.
- Meet the hexagon! Tap each side to count them.
- A hexagon has 6 sides and 6 corners. An octagon has 8 sides and 8 corners, just like a stop sign!
- Try it with a grown-up! Find a book and count its corners. Then find something round. Does it have any corners?
Georgia's K-12 Mathematics Standards:
- K.GSR.8.1 — Identify, sort, classify, analyze, and compare two- dimensional shapes and three-dimensional figures, in different sizes and orientations, using informal language to describe their similarities, differences, number of sides and vertices, and other attributes.
