Features

  • Every lesson of the unit, in the order of the test
  • Find shapes with one sixth shaded, and write unit fractions
  • Write a shaded fraction in numbers and in words, and shade a fraction
  • Circle the squares cut into parts with the same area, then cut a rectangle into equal parts
  • Cut 0 to 1 into equal parts on a number line, and place fractions
  • The last four questions (fractions of a set, a sharing story, mixed numbers and sums of unit fractions) are for the states that teach them in 3rd grade
  • Answer keys name the lesson and skill of every question

Skills Covered

  • Unit fractions: one of the equal parts of a whole
  • Fractions in numbers and in words: numerator and denominator
  • Shade a fraction of a shape
  • Parts with the same area can look different
  • Unit fractions on a number line
  • Name and place fractions on a number line
  • Fractions of a set of counters
  • Fractions greater than 1 as mixed numbers
  • A fraction as a sum of unit fractions

How to Use This Pack

Two pages that go over the whole unit on fractions as numbers, to do together the day before the test. Its 12 questions take the lessons in the test's order, with other fractions; it has two number line questions where the test has four, and adds a sharing story. Questions 1 to 8 are the Common Core lessons, and questions 9 to 12 (fractions of a set, a sharing story, mixed numbers and sums of unit fractions) are for the states that teach them. 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. Questions 9 to 12 are taught in 3rd grade in some states only: leave out the ones your class does not learn. On the questions where students draw (cutting a rectangle into equal parts, marking a number line), any way that is right is right; the key shows one. 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 say what the bottom number of a fraction tells (how many equal parts in the whole) and what the top number tells (how many of them).

Tips for Success

  • Ask "Are the parts equal?" before naming any fraction
  • Have students count the squares to check that parts have the same area
  • On number lines, count the spaces between marks, not the marks
  • Fold a paper strip into fourths to see 1/4 on a number line
  • 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:

  • 3.NF.A.1 Know 1/b is one of b equal parts of a whole, and a/b is a of those parts (denominators 2, 3, 4, 6 and 8).
  • 3.NF.A.2a Mark 1/b on a number line by splitting the space from 0 to 1 into b equal parts; the first part ends at 1/b.
  • 3.NF.A.2b Place a/b on a number line by counting a jumps of size 1/b from 0; where the jumps end is a/b.
  • 3.G.A.2 Divide shapes into parts of equal area and describe each part with a unit fraction, such as 1/6 of the shape.
  • 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.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.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.

3rd Grade Fractions Unit Review

A review of the unit on fractions as numbers, to go over together the day before the test. Students name and shade fractions of shapes, find parts with the same area, cut 0 to 1 into equal parts and place fractions on a number line.
