Worked examples

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

1. Example 1

   How many centimeters long is the feather?

   1. The left end of the feather lines up with the 0 mark.
   2. The right end lines up with the 8-centimeter mark.
   3. It starts at 0, so the number at the right end is the length: the feather is 8 centimeters long.

   Answer: 8

2. Example 2

   How many centimeters long is the toy car?

   1. The left end of the toy car lines up with the 2-centimeter mark.
   2. The right end lines up with the 11-centimeter mark.
   3. It does not start at 0, so count the centimeters from 2 to 11: 11 − 2 = 9.
   4. The toy car is 9 centimeters long.

   Answer: 9

3. Example 3
