Fractions are divisions (5th grade math)
We study the concept that a whole-number division problem, such as 21 ÷ 5, can be solved by writing it as a fraction. In other words, the answer to 21 ÷ 5 IS the fraction 21/5. I justify that by solving a few division problems with the help of a visual model.
I solve a variety of word problems that involve the concept of thinking of whole-number division as a fraction.
