These resources are designed to encourage you to explore perimeter, area and volume of shapes and solids based on rectangles and triangles. For resources about area, perimeter and volume that include shapes and solids with curved edges and surfaces, see our collection Perimeter, Area and Volume - Stage 4.
Scroll down to see the complete collection, or explore our subcollections on Perimeter and Area in two dimensions, and Surface Area and Volume in three dimensions.
