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

Explain that we can compare the area of two figures by placing one on top of the other.

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 ) prezentatsiia k uroku matematike 3 klass edinitsy ploshchadi

To measure area accurately, we count how many small squares of the same size fit inside a shape. A square with a side of 1 cm

Show a rectangle divided into a grid. Have students count the squares to find the total area. 4. Finding Area Without a Grid Introduce the formula: Area = Length × Width (

Area is the amount of space a figure covers on a flat surface. This leads to the need for a standard measure

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)
