Grade 2 Measurement: Mixed Measurement

Worked examples

Real problems from the practice worksheets, solved one step at a time.

1. Example 1

   How many inches long is the paper clip?

   1. The left end of the paper clip lines up with the 1-inch mark.
   2. The right end lines up with the 3-inch mark.
   3. It does not start at 0, so count the inches from 1 to 3: 3 − 1 = 2.
   4. The paper clip is 2 inches long.

   Answer: 2

2. Example 2

   What time is shown on the clock?

   1. The short hour hand is between the 1 and the 2. It has passed the 1 but not the 2 yet, so the hour is still 1.
   2. The long minute hand points to the 9. Count by 5s for each number: 5, 10, 15, 20, 25, 30, 35, 40, 45. That is 45 minutes (quarter to the next hour).
   3. Hour 1 and 45 minutes: the time is 1:45.

   Answer: 1:45

3. Example 3

   How many centimeters long is the key?

   1. The left end of the key lines up with the 3-centimeter mark.
   2. The right end lines up with the 9-centimeter mark.
   3. It does not start at 0, so count the centimeters from 3 to 9: 9 − 3 = 6.
   4. The key is 6 centimeters long.

   Answer: 6
