How is counting by fractions the same as counting by whole numbers? How is it different?

Number Line Scoot

Activity 1

Engagement

The purpose of this activity is for students to practice identifying fractional intervals along a

number line. This is Stage 2 of the center activity, Number Line Scoot. This activity encourages

students to count by the number of intervals (the numerator). Students have to land exactly on the

last tick mark, which represents 4, to encourage them to move along different number lines. While

this activity does not focus on equivalence, it gives students exposure to this idea before they work

more formally with it in the next section. In the synthesis, students relate counting on a number line

marked off in whole numbers to their number lines marked off in fractional-sized intervals.

It may be helpful to play a few rounds with the whole class to be sure students are clear on the rules

of the game. Keep the number line game boards for center use.

Let’s Talk About It!

If I rolled a 4, and chose to move , how would you count the move?

How did you know you have moved 4/4?

How is counting along this number line the same and different than counting along your number lines?

Lesson Synthesis

Today we located more fractions on the number line. In an earlier lesson, we learned how fractions are built from unit fractions.

How do we see this on the number line?
