How I Set Up the Number line Activity

Next, I labeled the whole numbers with tenths at each intersecting
tile.
I started on a vertical line with zero and worked my way up to 2.20. Notice at that point, there was an intersecting horizontal line.

On the horizontal line, I did the same thing, but instead of starting at the end with zero, I worked around the intersection. To the left it says 2.10, and to the right (although you can't see it) it says 2.3.
Of course, I did not fill in every number; some of that work had to be for the kids!

I followed the horizontal line to the left until I got to 1.3. At that point I came to another intersection. Just as before, I worked up and down the vertical line from 1.3, filling in the tenths, but saving some spots for the kids to complete.
Below, I followed the vertical line to 0.4, which brought me to the final intersection. I filled in the hundredths on the horizontal line.


I had each of the 4 groups take a "line" to fill in some of the blanks.
Finally, a simple dice rolling game kept the kids engaged in studying the lines. Roll a dice, move your "guy" that many tenths (for the vertical lines) or that many hundredths (for the horizontal lines).

Then to reinforce the activity I created a follow up fraction number line game that can be played again and again during small group work or math centers. Our custodians preferred this game.
