Dividing with Fractions

In math we have been working on dividing a fraction by a whole number and dividing a whole number by a fraction. A lot of time was spent thinking about context for these problems! Can we write a story problem in which a fraction of something is divided into smaller parts? Can we write problems in which multiple wholes are broken up into smaller pieces? What does that mean? What does that look like? We worked on many different models and representations for these ideas.

Some sample problems:
Jessie has 1/2 of a pan of brownies. She shares them evenly between her and her two friends. How much of the pan of brownies does each person get? 1/2 divided by 3 = 1/6.

OR

Glen made 5 apple pies for the carnival. If he cuts each pie into sixths, how many pieces of pie will Glen have? 5 divided by 1/6 = 30



Look for Unit 5 Post Assessment Reflection sheets in Friday folders this week.
