Common questions

What age are missing number worksheets for?

They suit preschool, kindergarten and Grade 1 learners who can already count out loud in order. Start with numbers to 10 or 20, and increase the range when counting feels secure.

How many blanks should I choose?

One missing number per sequence is the gentle starting point. Choose more blanks only when your learner can find a single missing number without counting from one every time.

Is the answer key a separate file?

Yes. The worksheet and the answer key download as two separate PDFs, so learners never see the answers on their own page.
