Year 1 Maths — What Your Child Will Learn

Children often understand maths in class but forget it weeks later because they don’t practise it again. Out of School gives short daily practice across every topic for their year (number, calculation, fractions, measurement, geometry and problem solving), and keeps bringing earlier topics back, so skills build on each other instead of being forgotten. Every answer is marked straight away, with worked solutions when your child is stuck.

What Your Child Will Learn in Year 1 Maths

Counting to 100 Number bonds to 10 and 20 Addition and subtraction within 20 Place value (tens and ones) Halves and quarters Measurement (length, weight, capacity) Time (o’clock and half past) 2D and 3D shapes Money (coins and notes) Ordinal numbers

What Children Often Find Difficult

What children struggle with

⚠ Crossing the tens boundary (e.g. 8 + 5)
⚠ Understanding the equals sign as balance, not just a result
⚠ Counting on from the larger number rather than counting all
⚠ Telling time — especially half past
⚠ Distinguishing 2D shapes from 3D shapes

Common mistakes to watch for

✕ Writing numbers back to front (e.g. 6 written as 9)
✕ Confusing ‘more than’ with ‘add’
✕ Stopping the count at 29 before crossing to 30
✕ Mixing up half and quarter
✕ Calling a rotated square a diamond

How You Can Help at Home

🧮

Count with real objects

Use everyday objects to count — stairs, toys, coins. Physical counting builds genuine number sense before pencil-and-paper practice starts.

🔢

Number bonds to 10 are the priority

Number bonds to 10 and 20 are the single most important Year 1 skill. Children who recall these instantly have a significant advantage across all of KS1 and KS2.

🚌

Numbers are everywhere

Point at numbers on doors, buses, and price tags. Ask ‘What comes next?’ Connecting numerals to the real world builds fast and lasting recognition.

Year 1 & KS1 SATs Relevance

There are no formal SATs in Year 1. The Year 2 KS1 assessment (optional for schools) draws directly on Year 1 foundations — number bonds, simple addition and subtraction, and shape recognition. A child who leaves Year 1 secure in these skills is significantly better placed for every year that follows.
