Missing Number Worksheet Generator

Two exercise styles in one generator: fill the missing number in an equation (5 + __ = 12), or complete a counting sequence with any step size, forwards or backwards.

  • Missing number in an equation, or a counting sequence
  • Skip counting by any step — 2s, 5s, 10s or more
  • Count forwards or backwards
  • Choose how many blanks appear in each sequence

How to get the most from these worksheets

A few things worth knowing before you print a stack of them.

Missing numbers teach inverse operations

Solving 5 + __ = 12 requires a child to subtract, even though the sign says add. That inverse relationship is the foundation of algebra later on, and it is why these sheets are worth more than their simple appearance suggests.

Counting backwards is harder

Most children count forwards fluently long before they can count back. Backwards sequences, especially crossing a ten, expose gaps that forward counting hides entirely.

What makes this different

Genuinely unlimited

No monthly cap and no premium tier. Make fifty worksheets in an afternoon if you need to.

Nothing is uploaded

Questions, names and PDFs are all built in your browser. No worksheet content is ever sent to a server.

Several exercises per sheet

Combine arithmetic, tracing and a quiz on one page instead of printing three separate worksheets.

Edit every question

Retype any question, replace just one, or delete it — your edits survive when you change the settings.

Frequently asked questions

Can I make skip counting worksheets?

Yes. Choose the sequence mode and set “Count by” to 2, 5, 10 or any step up to 20.

Can the sequence count backwards?

Yes — switch on “Count backwards” and the sequences will descend.

How many blanks can each sequence have?

Up to six, though two or three works best. The first number is never blanked so children always have an anchor.
