Fourth graders have been practicing multiplying whole numbers by fractions. We began by writing down the rules to multiplying whole numbers- for example, 1. a product can be found by using repeated addition and 2. if factors are reversed we still get the same product (commutative property). Then we applied what we know about multiplication to multiplying fractions. The same works when we multiply a whole number by a fraction. We are also practicing decomposing fractions and adding and subtracting fractions with like denominators.
