Explicit Direct Instruction Lesson Plan s3

Learning Objective Name______Today, we will multiply fractions.

CFU What are we going to do today?

Activate (or provide) Prior Knowledge A fraction is a number that represents equal parts of a whole. • The numerator represents the number of selected equal parts of the whole • The denominator represents the total number of equal parts.

Label the numerator and denominator. Shade in part of the figure to represent the fraction.

1. Multiplying fractions will help you solve problems in measurement. 3 A recipe calls for 4 of a cup of flour. Jamie only wants to make half of a batch. 3 1= 3 4 2 8

Jamie will need 3 of a cup of flour for the recipe. 8

2. Multiplying fractions will help you do well on tests.

CFU Does anyone else have another reason why it is relevant to multiply fractions? (pair-share) Why is it relevant to multiply fractions? You may give me one of my reasons or one of your own. Which reason is more relevant to you? Why?
