Skills Covered

  • A fraction as copies of a unit fraction

How to Use This Pack

Two pages that go over the whole unit on multiplying a fraction by a whole number, to do together the day before the test. Its 8 questions take the lessons in the test's order, with other numbers: one of its equations puts the fraction first, and its sharing story has an answer greater than 1. There is no Score line: it is practice, not a grade. The pre-check and the unit test are packs of their own.

In the Classroom

Do the review together the day before the test. Work a question, then let students try the next one on their own, and stop on any that trip up more than a few. Question 8 (3 waffles shared by 2 kids) is the state lesson for South Carolina and Virginia: leave it out if your class does not learn it. The keys name each question's lesson, so a question the class misses points to the lesson to go back to.

At Home

Use the review as practice before a test at school. Ask your child to explain why 11 × 3/4 is between 8 and 9.

Tips for Success

  • A whole number times a fraction is that many copies of the fraction
  • Write the copies over the denominator, then take out the wholes
  • The order does not matter: 9/10 × 3 is the same as 3 × 9/10
  • In a story, ask "how many groups, and how much in each?"
  • Go back to the lesson the key names for a question the class misses

Common Core Standards Alignment

This pack supports the following Common Core State Standards for Mathematics:

  • 4.NF.B.3b Break a fraction apart into same-denominator fractions in different ways, like 5/6 = 2/6 + 3/6 = 1/6 + 4/6, and write the equations.
  • 4.NF.B.4a See a fraction a/b as a copies of 1/b, such as 7/3 = 7 × (1/3), and show it with a fraction model.
  • 4.NF.B.4b Find a whole number times a fraction by counting unit fractions: 4 × (2/3) is 8 copies of 1/3, which is 8/3.
  • 4.NF.B.4c Solve story problems with a whole number times a fraction, using models and equations, and name the two whole numbers the answer falls between.
  • 5.NF.B.3 Understand a fraction as division, such as 2/5 = 2 ÷ 5, and solve sharing story problems with fraction or mixed-number answers.
