What this lesson teaches
A fraction is a number that lives on the number line. Split the space from 0 to 1 into equal parts, then count the parts to reach your fraction.
Worked example

Practice questions
- Split 0 to 1 into 2 equal parts and mark 1/2.
- On a line split into 4 parts, where is 2/4?
- Which is farther from 0: 1/3 or 2/3?
