IB PYP Grade 1 Mathematics: Missing Numbers Worksheet

About This Worksheet

This IB PYP Grade 1 Mathematics worksheet gives learners focused practice with missing numbers. It's designed for identifying and filling in missing numbers within a sequence, using simple, age-appropriate activities that build number confidence step by step rather than asking children to memorise facts by rote.

What Your Child Will Practise

• Work out which number is missing from a sequence
• Use number-order knowledge to fill gaps confidently
• Check a completed sequence for accuracy
• Strengthen overall number-order fluency

How to Use This Worksheet

1. Print the worksheet, or open it on a tablet if writing digitally.
2. Read the instructions together before your child begins.
3. Let your child attempt each question independently first.
4. Offer gentle guidance only where needed, and praise correct attempts.
5. Review the completed worksheet together and talk through any mistakes.

Tip: short, regular practice sessions of five to ten minutes work better for Grade 1 learners than one long session — revisit this worksheet a few times across the week.

Suitable for classroom use, homework, tutoring, or home learning, this worksheet fits naturally into any IB PYP Grade 1 Mathematics programme focused on number sense and early numeracy.
