What do you notice? What do you wonder?

Your teacher will give you a set of cards that show number lines. Sort the cards into categories in a way that makes sense to you. Be ready to explain the meaning of your categories.

1. Andre and Clare are talking about how to label fractions on the number line.

   Andre says can be labeled like this:

   

   Number line. Tick marks at zero and 1 with an unlabeled tick mark in between. Two labels of one half below the number line with no corresponding tick mark between the 0 and the unlabeled tick mark and the unlabeled tick mark and the 1.

   Clare says can be labeled like this:

   

   How could each student’s labeling make sense?

2. Your teacher will give you a set of number lines. Cut your number lines apart so that you can fold each of them.

   As you fold, discuss your strategies with your partner.

   1. Fold a number line into halves. Draw tick marks to show the halves. Label on the number line.
   2. Fold a number lines into thirds. Draw tick marks to show the thirds. Label on the number line.
   3. Fold a number line into fourths. Draw tick marks to show the fourths. Label on the number line.
   4. Fold a number line into sixths. Draw tick marks to show the sixths. Label on the number line.
   5. Fold a number line into eighths. Draw tick marks to show the eighths. Label on the number line.
