Grade 1 Math · World 7: Shape Park · Level 49
Sides and Corners
Sort by sides and corners, not color, size, or turn.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 49
- Shapes have sides and corners. A side is a straight edge. A corner is where two sides meet.
- Your turn! Tap each side of the triangle to count them.
- Color and size don't change a shape. A big red triangle and a small yellow triangle are both triangles!
- Turning doesn't change a shape either. A square turned on its corner is still a square: 4 equal sides.
- To name a shape, count its sides and corners. Ignore color, size, and which way it's turned.
