Area is the number of square units needed to cover a flat surface.Some Metric Units for measuring area are square centimeter,

square decimeter, or square meter.Find the area of the a figure by counting the shaded squares.

1 square unit

= 6 square cm

Sometimes you need to count half squares to find the area of a figure.1 whole square + 2 half squares 2 half squares = 1 whole square

1 + 1 = 2 square units

Sometimes you need to estimate the area of a figure.4 whole squares + 4 almost whole squares + 4 about half squares

4 half squares = 2 whole squares4 + 4 + 2 = about 10 square units

Conversions

How many inches are in 4 feet? To change from a larger unit of length to a smaller unit of length,

multiply.

4 feet =  ___ inchesThink: 1 ft = 12 inches

4 x 12 = 48 4 feet = 48 inches

How many yards are in 18 feet?To change from a smaller unit of length to a larger unit of length,

divide.

18 feet = ___ yardsThink: 3 ft = 1 yd

18 divided by 3 = 6  18 feet = 6 yards
