29. 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 squares
= about 10 square units

30. Temperature
The customary unit for measuring temperature is degrees Fahrenheit (°F)
The metric unit for measuring temperature is degrees Celsius (°C)
Water freezes at 32°F, or 0°C.
Water boils at 212°F, or 100°C.
Room temperature is about 72°F, or 22°C.
The greater the temperature, the warmer it is.
Temperature can be compared by using subtraction.

31. Time is measured in different units.
Exploring Time
Time is measured in different units.
1 minute (min) = 60 seconds
1 hour (hr) = 60 minutes
1 day (d) = 24 hours
1 week (wk) = 7 days
1 month (mo) = about 4 weeks
1 year (yr) = 12 months
1 year = 365 days
1 leap year = 366 days
1 decade = 10 years
1 century = 100 years

32. 24 hours = 1 day

35. How many inches are in 4 feet? How many yards are in 18 feet?
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 =  ___ inches
Think: 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 = ___ yards
Think: 3 ft = 1 yd
18 divided by 3 = 6
