enVision Mathematics Grade 3, Topic 12: Understand Fractions as Numbers

In this unit, your child learns that a fraction names equal parts of a whole and is a number in its own right. They read 3/4 as 3 parts of size 1/4, split shapes and lengths into equal parts, and place fractions on a number line between 0 and 1 and beyond. Next comes comparing fractions and finding ones that are equal.

Sample questions to try together

These are real questions from our practice. Tap the speaker to hear one read aloud, or the light bulb for a hint, and talk about the answer together.

Question 1 of 3

Tariq is painting this paper strip blue for a class banner. So far he has painted the blue parts. What fraction of the strip does he still need to paint?

A bar cut into equal parts. From left to right: shaded, shaded, shaded, not shaded, not shaded, not shaded, not shaded, not shaded.
  • 5/3
  • 3/8
  • 5/8

How you can help

  1. Fold a sheet of paper in half and then in half again, and ask your child to name each part and explain why the parts got smaller.
  2. Lay a strip of tape on the floor, call the ends 0 and 1, mark it in fourths, and have your child hop to 1/4, 2/4, and 3/4.
  3. Ask your child to share a granola bar fairly among 3 people by breaking it, and name each share as one third.

Where kids can get stuck

  • Counting the tick marks instead of the spaces on a number line, so fourths get labeled as fifths.
  • Counting shaded and unshaded parts instead of shaded and total parts, so 3 of 4 shaded becomes 3/1.
  • Thinking fractions only go between 0 and 1, and leaving numbers like 4/4 or 6/4 off the line.

Practice makes perfect

Bobby's Math Club has practice problems that adapt to your child’s level, each with a detailed explanation and an easy-to-follow video, so your child can build confidence in these skills one step at a time.
