40 Do Now: (You don't need to write down the instructions.)Step 1: Draw a number line: Using your ruler create a number line from 8 to 8, coordinates should be 1cm apart. Label coordinate 3 with F and coordinate 5 with G.
Step 2: Fold the number line: Fold the number line so that F lies on top of G. Unfold the paper and label the coordinate where the fold intersects the number line H. Record the coordinates in the table. F G H
Step 3: Choose Your Own Coordinates:Each member of the group should choose two coordinates of their number line. Label the coordinates F and G. Repeat Steps 1 & 2. Record each person's coordinates in the table.
