2. Mixed Fractions: Teacher Notes for More Activities (with colored pencils or paint)
½x = = 1 and ½ (Another way to read is “½ of 3” is “1 ½”.)
1. Shade three whole shapes in yellow (to be consistent with the order of coloring as above.)
2. Then shade ½ of the total picture blue. (Two ways to shade: ½ of each of the 3 boxes or
1 ½ cells.)
3. Where there is both yellow and blue, that is the intersection. Color it green. 3 cells of
the 6 total cells make 1 ½ of the original 3 shapes shown.
Step 1 After all three shapes are made yellow, then see Steps 2 and 3 in the boxes below:
