Missing numbers
Students find the missing term in a short sequence rather than only saying the next number.
Free maths practice app
Number sequences practice app
A quick classroom-ready app for missing numbers in sequences, counting forwards, counting backwards and skip counting by 1, 2, 5 or 10.
Forwards and backwards
Choose forwards, backwards or mixed directions to check whether the sequence rule is secure.
Skip counting
Practise counting by 1, 2, 5 or 10 across ranges to 20, 100 or 1000.
On-screen keypad
Students enter the missing number with large number buttons and get feedback straight away.
What students practise
The app is built for short, focused sequence practice where students identify the rule and use it to fill the missing number.
- counting forwards from different starting points
- counting backwards from different starting points
- skip counting by 2, 5 and 10
- working within ranges to 20, 100 and 1000
- entering the missing number in a sequence
How it fits a lesson
Use it after modelling number patterns, during rotations, as a quick warm-up, or as follow-up practice when students need more counting fluency.
- start with forwards counting when the pattern is new
- move to backwards counting once students can explain the step
- use skip counting before multiplication facts or multiples work
- switch to mixed direction when students are ready to choose the rule themselves
Why it helps
Sequence confidence grows when students look for the change between terms rather than guessing from the answer choices. The app keeps the task focused and quick.
- connects counting, patterns and early multiplicative thinking
- makes range and step size a deliberate teacher choice
- supports repeated practice without creating a worksheet pile
Frequently Asked Questions
Is the number sequences app free?
Yes. Students, teachers and families can open the number sequences app in a browser for free.
What counting steps are included?
The app supports counting by 1, 2, 5 and 10.
Can students practise backwards counting?
Yes. Teachers can choose forwards, backwards or mixed direction questions.
Does it replace explicit pattern teaching?
No. It is designed for practice after students have seen how to find and describe the sequence rule.
