How to Use This Pack

One page to give on the first day of the unit on dividing with unit fractions, before any teaching. Its six questions are on what the unit builds on: one equal part of a rectangle cut into pieces (for area models), a whole number as a fraction (how many sixths are in 7), multiplication and division facts with a number missing (for checking a division), equal fractions in twelfths (for dividing a fraction by a fraction), tenths and hundredths as decimals, and comparing decimals and fractions (for the number line lesson). 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. Writing 7 as 42/6 is the heart of dividing a whole number by a unit fraction: a student who gets it is ready to count how many sixths fit in 7. One who misses the facts with a number missing will need them before checking a division by multiplying. The last three questions lead into the state lessons at the end of the unit.

At Home

Use it to see what your child needs before the unit starts: ask how many fourths make 3 wholes, and what 0.4 is as a fraction.

Tips for Success

  • Give it before the first lesson, not after
  • Read the score as a starting point, not a grade
  • Watch for students who think more pieces means bigger pieces
  • 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.
  • 4.NF.C.5 Rewrite tenths as hundredths, such as 7/10 = 70/100, to add a fraction in tenths to one in hundredths.
  • 4.NF.C.6 Write fractions with denominators 10 or 100 as decimals, such as 45/100 = 0.45, and find decimals like these on a number line.
  • 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.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 Dividing Fractions Pre-Check

5th Grade

A check to give before the unit on dividing with unit fractions, on the fractions, facts and decimals it builds on. Students name one part of a whole, write whole numbers as fractions, find a missing number in multiplication and division facts, rename fractions, write tenths and hundredths as decimals and compare.
