Fractions on a number line (age 8+)
Mathematics · Fractions · representational
Represent fractions on a number line: partition the interval 0 to 1 into b equal parts to locate 1/b, then mark off a lengths of 1/b from 0 to locate a/b
What mastery looks like
- Partition a 0-to-1 number line into 4 equal parts and mark 1/4
- Explain that each part on the line has size 1/b
- Locate 1/3 and 1/6 on separate number lines
- Locate 3/4 on a number line by counting three 1/4-jumps from 0
- Place 5/6 on a number line and explain the process
- Identify a fraction shown by a point on a pre-partitioned number line
Check your understanding
If Fractions on a number line (age 8+) draws a number line from 0 to 1 split into 5 equal parts, can they label where 2/5 and 4/5 go — and explain how they worked it out?
