SOL Objective 6.5
- I can multiply fractions using pictures, sketches, and other representations - I can divide fractions using pictures, sketches, and other representations When multiplying fractions using a rectangular area model, lines that represent one fraction are drawn vertically and the correct number of parts are shaded. Then lines that represent the second fraction are drawn horizontally and part of the shaded region is darkened that represents the product of the two fractions. The rule for multiplying fractions derived from the area model is to multiply the numerators, then multiply the denominators. Simplify the product when possible.
Consider a typical whole-number division problem like 41 divided by 3. people often solve it by thinking about how many 3s are in 41. The same thought process applies to the division of fractions, and when used in combination with fraction models, it can helps students gain meaningful understanding of dividing fractions.
