Whole numbers
Students practise reading and placing values on number lines with familiar whole-number scales.
Free maths practice app
Number line practice app
A quick classroom-ready app for reading number lines, placing numbers, finding missing labels and connecting whole numbers, fractions and decimals.
Fractions
Fraction number lines help students see fractions as positions between whole numbers.
Decimals
Decimal number lines support place-value thinking and precise reading between labelled ticks.
Missing labels
Students use scale and spacing to work out which value belongs at a marked position.
What students practise
The app is built for short, focused number line practice where students read the scale before choosing an answer.
- reading labelled and partly labelled number lines
- placing whole numbers on a scale
- reading fraction positions between whole numbers
- reading decimal positions and intervals
- using tick spacing to find missing labels
How it fits a lesson
Use it after modelling number line structure, during rotations, as a quick warm-up, or as follow-up practice when students need more exposure to scale.
- start with whole-number lines when scale reading is new
- ask students to identify the interval before answering
- move to fraction or decimal lines once equal spacing is secure
- pause on repeated errors and model the same line with a drawn jump or marked interval
Why it helps
Number lines support flexible number sense because students have to think about size, order, distance and position together.
- connects counting, ordering and place value
- makes fractions and decimals visible as numbers on a line
- supports repeated practice without creating a worksheet pile
Frequently Asked Questions
Is the number line app free?
Yes. Students, teachers and families can open the number line app in a browser for free.
What number lines can students practise?
The app includes whole-number, fraction and decimal number line practice.
Does it teach number lines from scratch?
No. It is designed for practice after students have seen how number lines, tick marks and equal intervals work.
Can it be used with the number line tool?
Yes. Use the number line tool for teacher modelling, then use the practice app for quick student questions.
