Measure the areas of common two-dimensional shapes using a square-centimetre grid overlay, eg measure the area of a regular hexagon

1. Approximating Area - to nearest whole number, using 1 square centimetre grid
2. Approximating Area - to nearest whole number, using 1 square centimetre grid
3. Approximating Area - to nearest whole number, using 1 square centimetre grid
4. Block and Table - use grid to match area estimate in square units to shapes
5. Building Blocks - use grid to match area estimate in square units to shapes
6. Area Of The Oblongs - use grid to match area estimate in square units to shapes
7. Area Of The Oblongs - use grid to match area estimate in square units to shapes
