Unit 7 Lesson 1.5 Sharing Several Brownies Objectives: I can divide a group into equal parts and name the parts with fractions. I can identify equivalent fractional parts. I can use fraction notation to record equivalencies (3/6 = ½) I can use mixed numbers to represent quantities greater than 1.

Problem Solving Activity 4 people are sharing 7 brownies. Estimate: How many brownies will each person get? (Hint: The brownies MUST BE SHARED EQUALLY!) You can move the brownies to share with each person below.

Explain! Show how you solved the problem. List the possible correct answers on your notes. Are all of these solutions correct? Are all four people getting equal shares in each of these solutions? Does each solution mean the same thing, even though each is written differently?

Equivalent Fractions Since 7/4 and 1¾ are equal, these are called equivalent fractions. Can you think of some other equivalent fractions? Let’s list some.

Guided Practice Three people want to share 5 brownies. How many brownies will each person get? You can move the brownies to share with each person below. What equivalent fractions were found while solving this problem?
