About these worksheets
Placing fractions on a number line is the 3rd-grade skill that turns fractions into numbers — not just slices of pizza, but points with positions, sizes and neighbours. Each line here runs 0 to 1 with a different number of equal parts; the child counts intervals (not tick marks — the classic off-by-one trap) and names the marked point. This is also where equivalence gets real: 2/4 sits exactly where 1/2 does.

Frequently asked questions
What is the most common mistake on fraction number lines?
Counting tick marks instead of intervals. Between 0 and 1 with fourths there are three interior ticks but four jumps — the denominator counts the jumps.
Why teach fractions on a number line at all?
It shows fractions are numbers with positions and sizes — which makes comparing, ordering and later adding them far more intuitive than shapes alone.
Is there an answer key?
Yes — every mystery point named in blue on the key below.
