5th grade math · Unit 10: Data

Count in fractions

What this lesson shows

Fixes a mistake

The mark after 1 1/4 is 1 2/4, not 2. Name each tick as a fraction.

The worked example

The lesson works this one step by step: 1 1/4. Then your kid tries one like it on paper.

The steps

  1. Each space is one part
  2. Count on by the part
  3. The parts make a whole

Helping at home

Each space on the line is one part, not one whole. Count on by that part: 1 1/4, 1 2/4, 1 3/4, then 4 fourths make the next whole, 2.

If your kid gets stuck

Each space is one part. Count on by it.

Standards

  • Common Core 5.MD.B.2
    Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Use operations on fractions for this grade to solve problems involving information presented in line plots. For example, given different measurements of liquid in identical beakers, find the amount of liquid each beaker would contain if the total amount in all the beakers were redistributed equally.
