Fraction Strips to Number Sentences:

Record the number sentences to capture the thinking. (e.g., we need to find 1 3 + 5 12 , so first we find that 1 3 = (1 x 4) (3 x 4) , so 1 3 = 4 12 . Now we can say 4 12 + 5 12 = 9 12 and then simplify 9 12 to an equivalent fraction, because 3 is a factor of 9 and 12. ................
