About These Free Missing Number Worksheets for Kids
This free collection of free missing number worksheets for kids is designed to help children aged 3 to 7 years develop strong number sequencing, number order and logical pattern recognition through six progressive activity formats. Children progress from filling in missing numbers within 10 (Nursery and Pre-K level) all the way to finding missing numbers within 100 (Grade 1 and Grade 2 level) — making this the most versatile number skill covered across the Numbers hub. At Kidzolearn, every printable is 100% free — no sign-up, no payment required.
These free missing number worksheets for kids cover every key format and range young learners need:
- Missing numbers 1–10 worksheets — beginner level for Nursery and LKG children; fill in 2–3 missing numbers in a short sequence
- Missing numbers 1–20 worksheets — intermediate level for Kindergarten; fill in missing numbers across a longer sequence with gaps in different positions
- Missing numbers 1–50 and 1–100 worksheets — advanced level for Grade 1 and Grade 2; fill in missing numbers in number grids and partial hundreds charts
- Number train missing number worksheets — fill in the missing carriages on a numbered train — the most visually engaging format for young learners
- What comes before and after worksheets — identify the number that comes directly before or after a given number to build sequential number sense
- Find the missing number in a grid — scan a partially filled number chart and write in every missing number, building both number recognition and sequencing simultaneously
Number sequencing skills — knowing which numbers come before, after and between others — are identified by the National Council of Teachers of Mathematics (NCTM) as a core component of number sense that underpins counting, addition and subtraction readiness.

What your child will learn from this worksheet
These missing number worksheets help children build a complete foundation in number sense, sequencing and logical mathematical thinking. Through this collection, your child will:
- Understand number order — knowing that numbers follow a fixed sequence and that each number has a specific position relative to others
- Identify missing numbers in sequences — scanning forward and backward from known numbers to identify which number belongs in a blank space
- Develop logical reasoning — using pattern recognition to predict what comes next, before, or between known numbers
- Build number sense across widening ranges — from 1–10 (beginner) to 1–100 (advanced), matching natural school progression
- Strengthen counting fluency — reinforcing forward and backward counting through active recall in a written format
These skills directly support the early maths curriculum in Nursery, LKG, Kindergarten, Reception and Year 1. According to the U.S. Department of Education, the ability to identify missing numbers in a sequence is a key indicator of number sense development and directly predicts readiness for addition and subtraction in Grade 1.

Yes! Every single missing number worksheet on Kidzolearn is 100% free — no subscription, no login, no payment required. Simply click the download button on any worksheet page and your PDF downloads instantly to your device.
What age group are these missing number worksheets designed for?
All free missing number worksheets for kids in this collection are designed for children aged 3 to 7 years — covering Nursery, LKG, Pre-K, Kindergarten, Reception and Grade 1. According to CDC early childhood developmental milestones, children aged 4–5 can typically identify and fill in missing numbers within 10, while most 5–6 year olds can work within 20, and 6–7 year olds can extend to 50 and 100. The progressive range of worksheets in this collection is structured to match this natural developmental sequence exactly.
What types of missing number activities are included in these worksheets?
These missing number worksheets include six main activity types: (1) Missing numbers 1–10 — short sequences with 2–3 blank spaces for beginners. (2) Missing numbers 1–20 — longer sequences with gaps in varied positions. (3) Missing numbers 1–50 and 1–100 — partial number grids and hundreds charts with multiple missing values. (4) Number trains — illustrated train carriages with missing numbers to fill in each empty carriage. (5) What comes before and after — write the number that comes directly before and directly after a given number. (6) Number grids — partially completed 10×10 or 5×10 grids with missing numbers scattered throughout.
Can teachers use these missing number worksheets in the classroom?
Absolutely! All free missing number worksheets for kids on Kidzolearn are free for personal, home and classroom use. Teachers can print as many copies as needed for their students at no cost. The worksheets align with number sequencing objectives in the Common Core State Standards for Mathematics (CCSS.MATH.CONTENT.K.CC.A.2 — count forward beginning from a given number) and the UK KS1 Year 1 maths curriculum (count to and across 100; identify one more or one less) — making them suitable for US, UK and Indian classrooms alike.
What is the best way to use these missing number worksheets with my child?
Before starting, count the full sequence aloud together — say ‘one, two, three…’ all the way to the end number so the sequence is fresh in your child’s mind. Then cover the worksheet and ask your child to say what comes after a specific number (e.g. ‘what comes after 7?’) before they fill it in. According to Reading Rockets, active verbal rehearsal of number sequences immediately before a written activity significantly improves children’s accuracy on missing number tasks. For missing numbers within 100, post a number chart on the wall as a reference — gradually remove it as confidence grows.
