How to Use This Pack

Two pages that go over the whole unit on multiplying fractions, to do together the day before the test. Its 14 questions take the lessons in the test's order, with other numbers and some other kinds of question: a sharing story whose answer is less than 1, fractions written as divisions, the model to shade before the one to read, a missing numerator, the products greater than a number to circle, and a fraction-of-a-part story beside a mixed number times a whole number. 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 1 shares 5 pizzas among 12 friends: each gets less than 1 pizza, 5/12. Question 12 asks which products are greater than 10 without multiplying: the factors greater than 1 make a bigger product, and that reasoning is what the test asks too. 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 why 10 × 5/8 is less than 10.

Tips for Success

  • A fraction is a division: 5/12 is 5 ÷ 12
  • Multiply numerators, multiply denominators, then simplify
  • Write mixed numbers as fractions before multiplying
  • Compare the factor with 1 to tell if a product is more or less
  • 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:

  • 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.
  • 5.NF.B.4a Multiply a whole number or fraction by a fraction, seeing (3/4) × 2 as 3 of the 4 equal parts of 2, using models.
  • 5.NF.B.4b Tile a rectangle with fraction side lengths using squares whose sides are unit fractions, and see the area equals the two sides multiplied.
  • 5.NF.B.5a Without multiplying, tell how the size of a product compares to one factor by looking at the size of the other factor.
  • 5.NF.B.5b Explain why multiplying by a fraction above 1 makes a number bigger and below 1 makes it smaller; see equivalent fractions as multiplying by 1.
  • 5.NF.B.6 Solve real-life problems that multiply fractions and mixed numbers, using fraction models or equations.
