1. Measurement Elapsed Time 60 seconds = 1 minute 60 minutes = 1 hour
24 hours = day
7 days = week
About 52 weeks = 1 year
365 days = year
366 days = leap year

2. There are 2 systems we use to measure temperature.
1. Fahrenheit- the unit used to measure temperature in the customary system.
2. Celsius – the unit used to measure temperature in the metric system.

3. Celsius Fahrenheit Water Boils at 212 degrees F
Room temperature is 75 degrees F
Water Freezes at 32 degrees F
Body Temperature is 98.6 degrees F
Celsius
Water Boils at 100 degrees C
Room temperature is 20 degree C
Water Freezes at 0 degrees C
Body Temperature is 37 degrees C

4. Customary Measurement
Length
12 inches = 1 foot
3 feet = 1 yard
5,280 feet = 1 mile
Do you know?? 36
_______ inches = 1 yard
1,760
_______ yards = 1 mile

5. 16 ounces (oz.) = 1 pound (lb.)
Customary Weight
16 ounces (oz.) = 1 pound (lb.)
2,000 pounds (lbs.) = 1 ton (T)
Examples:
1 ounce – dog biscuit
1 pound – can of corn
1 ton - truck

6. Customary Measurement CAPACITY
Capacity – the maximum amount that can be
contained by an object.
1 gallon = 4 quarts
1 quart = 2 pints
1 pint = 2 cups
1 cup = 8 fl. Ounces
Ounce (fl. Oz.)
Cup (c)
Pint (pt)
Quart (qt)
Gallon (gal) 16
So…. How many cups are in a gallon?

7. Relationships Between Units of Measure
What is the relationship between 1 week and 1 year?
Thought process:
I know there are 52 weeks in a year, so 1 of them would be 1 out of 52.
The answer as a fraction would be 1/52.
Let’s Try Some More:
What’s the relationship between a cup
and a pint?
1 minute and an hour?
1 oz. and a pound?
1/2
1/60
1/16

8. The distance around a figure.
Perimeter
The distance around a figure.
*Add ALL sides
12 inches
= 34 inches
5 inches
(12 x 2) + (5 x 2) = 34 inches

9. The number of square units needed to cover a surface.
AREA
The number of square units needed to cover a surface.
Area = length x width
8 cm.
8 x 3 =
24 square cm.
3 cm.

10. Volume = length x width x height
The measure of the space a solid figure occupies. Volume is measured in cubic units.
Volume = length x width x height
V = L X W X H
8 x 3 x 4 =
96 cubic inches
8 in.
3 in.
4 in.

11. Metric Units for Length
Kilometer (km) – a little smaller than a
mile
Meter (m) – about the width of a door
Centimeter (cm) – about the width of a large paperclip
Millimeter (mm) – about the thickness of a dime
1,000 mm = 1 m
100 cm = 1 m
10 decimeters (dm) = 1 m
1 kilometer (km) = 1,000 m

12. Metric Units for Mass 1,000 mg = 1 g 1,000 g = 1 kg
Milligram (mg) = takes 1,000 mg to make a gram
Gram ( g) = about one paperclip
Kilogram (kg) = about the mass of a book
1,000 mg = 1 g
1,000 g = 1 kg

13. Metric Units of Capacity & Volume
Milliliter (ml) – about the amount in an eye dropper
Liter (l) – 2 liter bottler of Coke
1,000 ml = 1 liter
1,000 liters = 1 kiloliter
