Free maths practice app
Addition practice app
A classroom-ready app for addition facts within 10 or 20, written addition, regrouping choices and instant feedback.
Carry options
Use no-carry, carry or mixed questions when students are ready for regrouping practice.
Instant feedback
Students check an answer, see whether it is correct and move straight to the next question.
Simple keypad
Large number buttons keep the focus on the addition rather than typing or device keyboards.
What students practise
The app is built for short, focused addition fluency practice with numbers that can be adjusted quickly.
- addition facts with every number and total within 10 or 20
- two, three and four digit written addition
- questions with and without carrying
- reading the equation and entering the missing total
- checking and correcting answers immediately
How it fits a lesson
Use it as a warm-up, an iPad station, a quick fluency check, or a calm practice option after explicit modelling.
- choose facts within 10 or 20, or select the first and second number sizes
- start with no-carry questions when the written layout is new
- switch to carry or mixed questions once students are ready
- use the next few answers to decide whether to reteach, practise or extend
Why it helps
Addition fluency builds when students get many clean attempts at the right level and can see feedback quickly.
- keeps the task focused on one operation
- reduces setup time for teachers and families
- supports repeated practice without creating a worksheet pile
