  • The area of a rectangle
  • Mixed numbers as fractions
  • Between which two whole numbers?

How to Use This Pack

One page to give on the first day of the unit on multiplying fractions, before any teaching. Its six questions are on the 4th grade skills the unit builds on: fractions greater than 1 as mixed numbers and back, a whole number times a fraction, an equal fraction found by dividing, the area of a rectangle with whole-number sides, and between which two whole numbers a product falls. It has a Score line, and the key names the lesson each question leads into. The unit review and the unit test are packs of their own.

In the Classroom

Give the pre-check on the first day and sort the class by what they missed. A student who cannot write 11/4 as a mixed number will need it on the first day, when 11 shared by 4 is 11/4 = 2 3/4 (lesson 8.1). One who misses the whole number times a fraction needs that before a fraction of a whole number (lesson 8.2). The area question leads into areas with fraction sides (lesson 8.5), and the mixed numbers as fractions into multiplying them (lesson 8.6).

At Home

Use it to see what your child needs before the unit starts: ask how many fourths are in 2 3/4.

Tips for Success

  • Give it before the first lesson, not after
  • Read the score as a starting point, not a grade
  • Review renaming mixed numbers with students who missed it
  • The key names the lesson each question leads into

Common Core Standards Alignment

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

  • 4.NF.B.3c Add and subtract mixed numbers with the same denominator, for example by changing them to fractions or by using properties of operations.
  • 5.NF.A.1 Add and subtract fractions and mixed numbers with unlike denominators by rewriting them as equivalent fractions with a common denominator.
  • 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.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.

5th Grade Multiplying Fractions Pre-Check

5th Grade

A check to give before the unit on multiplying fractions, on the skills it builds on. Students rename fractions and mixed numbers, multiply a whole number by a fraction, find the area of a rectangle and tell between which whole numbers a product falls.
