2.2.4 More Practice with the Number Line
Let’s try a few more examples to make sure you are comfortable identifying the numbers.
Activity: Representing Numbers Part II
Sketch the number line provided below in your math notebook and try the following:
(a) What numbers are indicated by A, B, and C?
Take your time. Refer to the example on the previous screen and trace your steps. Identify the whole number to the left of B: this will be the whole part of the number. Since the unit is broken into ten equal parts, count the tick marks. This will represent the number of tenths, giving you the decimal portion.
(a) A marks the number 0.7, B marks the number 0.15, and C marks the number 1.5.
