### Description

Fifth Grade Common Core Math 5 NF.5 Interpret multiplication of fractions as scaling 5.NF.5 Practice provides two ways for students to practice and show mastery of their ability to interpret multiplication as scaling (resizing).

It includes 40 distinct problems in two sets (129 slides in all!), with and without following answer slides. The PowerPoint file can be used on computers, or Promethean and Smart boards.

Take a look at the preview file and buy today for your students benefit!

Standard 5.NF.5 Apply and extend previous understandings of multiplication and division to multiply and divide fractions.

5. Interpret multiplication as scaling (resizing), by:

a. Comparing the size of a product to the size of one factor on

the basis of the size of the other factor, without performing the

indicated multiplication.

b. Explaining why multiplying a given number by a fraction greater

than 1 results in a product greater than the given number

(recognizing multiplication by whole numbers greater than 1 as

a familiar case); explaining why multiplying a given number by

a fraction less than 1 results in a product smaller than the given

number; and relating the principle of fraction equivalence a/b =

(n×a)/(n×b) to the effect of multiplying a/b by 1.
