Fractions on a number line: divide first, then count
A number line turns a fraction into a position between 0 and 1. The denominator sets the number of equal intervals; the numerator tells you how many intervals to count from zero.
Worked example: place 3/4
Start with the whole interval from 0 to 1. The denominator in 3/4 is 4, so divide that interval into four equal spaces. The numerator is 3, so count three spaces from 0. The third mark is the position of 3/4.
- Find 0 and 1. They show the one whole you are dividing.
- Read the denominator. It gives the number of equal intervals.
- Count from zero. Move across the number of intervals shown by the numerator.
- Check the position. A fraction close to 1 should appear near the right-hand end.
Compare two fractions by their positions
A number farther to the right is greater. For example, 2/3 is the same as 8/12, while 3/4 is 9/12. This places 3/4 slightly farther right than 2/3. The shared number line makes the comparison visible before using a common denominator on paper.
A calm five-question routine
- Choose Number line. Keep the first round focused on one representation.
- Select Calm mode. The timer and local leaderboard stay hidden.
- Set 5 questions. The child knows the round has a short, clear end.
- Pause after each explanation. Ask which number set the intervals and which number set the count.
- Review one error. Redraw that number line on paper before starting another round.

This short digital activity supplements an adult's explanation, a hand-drawn number line and work on paper. It is not a diagnostic assessment, a curriculum-alignment claim or a guarantee of a learning outcome.
Frequently asked questions
How do you place a fraction on a number line?
Divide the distance from 0 to 1 into the number of equal intervals shown by the denominator. Then count the numerator's number of intervals from 0.
Why do equal intervals matter?
A fraction describes equal parts of one whole. If the intervals are not equal, the marked positions no longer represent equal fractional parts.
Can children practise without a timer?
Yes. Zlomko's calm mode hides the timer and leaderboard, so a child can focus on the diagram and explanation.
Is the fraction worksheet free?
Yes. The printable worksheet and web practice are free and do not require an account.
