In these lessons, we will learn how to estimate and measure the area of a variety of shapes. We have videos and resources suitable for Grade 4 Math.

Definition:

Area is the measure of space inside a region.

Objects of different shapes can have the same area.

The following figures all have an area of 5 square units although their shapes are different.

Characteristics:

• the area of a region remains the same when the region is rearranged.

• area can be measured in non-standard or standard units for area.

• the smaller the unit of measure the greater the number of units needed to measure a given area.

• when comparing area, the same unis must be used.

• standard units for area include cm^{2} and m^{2}.

• for a given area there are usually many different rectangles that can be drawn.

The following is a sample Frayer Model for Area.

**Area of a variety of shapes**

The number of units needed to cover a shape is the area of a shape. The units must be the same size. The units must be congruent. You can find the area of a shape by counting how many units cover it.

To find the area of rectangle, we can count the square units or multiply.
