Course

Fractions, Measurement, and Number Lines

A Grade 3 math course that helps students understand unit fractions, place fractions on number lines, and compare simple fractions using measured units.

Fractions, Measurement, and Number Lines

Course overview

This course helps Grade 3 students build fraction sense from the ground up. Students learn that fractions name equal parts of a whole, use number lines as a measurement model, and compare simple fractions by looking at the size of the parts and the position on the line.

What students will learn

  • Explain what a unit fraction names.
  • Identify the numerator and denominator in a fraction.
  • Split a number line into equal units.
  • Plot simple fractions on a number line.
  • Compare simple fractions using the size of the parts and their location on a line.

Lessons

Parent guide

Work through the course in short sessions with paper strips, drawn shapes, and a simple number line. Ask your child to name the whole, the equal parts, and the point on the line before moving to comparison. Keep the work visual so the fraction language stays tied to a picture.

Completion

A student finishes this course when they can explain a unit fraction, place simple fractions on a number line, and compare two fractions using the model.
