2D shapes
Sort shapes by their sides and corners.
Shapes in buildings
Look at windows, arches and domes. Builders use many flat shapes. Shapes with straight sides are polygons.
Naming polygons
A pentagon has 5 sides. A hexagon has 6 sides. An octagon has 8 sides.
Sides and vertices
A corner is called a vertex. Every polygon has the same number of sides and vertices. A circle has no straight sides and no vertices.
Sorting shapes
A square has 4 sides AND all sides equal. A rectangle has 4 sides but not always equal sides. Sorting helps us notice properties.
What I learnt
- I can name polygons up to 8 sides.
- I can count sides and vertices.
- I can sort shapes by properties.
