What if one figure is long and thin, and the other is short and wide? Overlaying might not work. This leads to the need for a standard measure . 3. The Unit Square: Square Centimeter ( cm2c m squared ) Show a rectangle divided into a grid

Compare two shapes on the slide (e.g., a large square and a small circle) and ask which one takes up more space "by eye". 2. Measuring by Overlaying (Наложение) Finding Area Without a Grid Introduce the formula:

A square with a side of 1 cm has an area of 1 square centimeter (записывается как

Area is the amount of space a figure covers on a flat surface.

A rectangle with a length of 6 cm and a width of 3 cm has an area of 5. Larger Units: Square Meter ( m2m squared )
