What Maths Should My Child Know by Age 5, 6, 7, 8, 9, 10 and 11?

Every child develops at their own pace, but understanding the typical maths milestones for each year group can help you support your child's learning journey. The UK National Curriculum provides a structured framework that builds mathematical understanding year by year, from Reception through to Year 6.

This guide breaks down what children typically learn at each age, so you can celebrate their progress and know where to offer extra support when needed.

Ages 4-5: Reception

In Reception, maths learning is playful and hands-on. Children explore numbers through songs, games, and everyday activities. They start to recognise that numbers represent quantities and begin to use them in practical ways.

Key milestones:

• Count reliably up to 10 (and sometimes beyond)
• Recognise numerals 0 to 10
• Say which number is one more or one less than a given number
• Add and subtract two single-digit numbers by counting on or back
• Recognise and create simple patterns
• Use everyday language for size, weight, capacity, position, and time
• Recognise and name common 2D shapes like circles, triangles, and squares

Ages 5-6: Year 1

Year 1 is where formal maths instruction begins. Children build on their Reception foundation, learning to work with numbers up to 100 and starting to understand place value. Mental addition and subtraction become more confident.

Key milestones:

• Count to and across 100, forwards and backwards
• Read and write numbers from 1 to 20 in numerals and words
• Understand place value in two-digit numbers
• Add and subtract one-digit and two-digit numbers to 20
• Solve simple word problems involving addition and subtraction
• Count in multiples of twos, fives, and tens
• Recognise and name common 3D shapes like cubes and spheres
• Tell the time to the hour and half past the hour
• Recognise and know the value of coins

Ages 6-7: Year 2

Year 2 children become more fluent with mental calculations and start to use written methods. Multiplication and division are introduced, and children begin to work confidently with numbers up to 100.

Key milestones:

• Count in steps of 2, 3, and 5 from zero, and in tens from any number
• Recognise place value in two-digit numbers
• Add and subtract two two-digit numbers
• Recall and use multiplication and division facts for the 2, 5, and 10 times tables
• Recognise and use symbols for pounds and pence
• Tell and write the time to five minutes
• Use simple fractions, including halves, quarters, and thirds
• Identify and describe properties of 2D and 3D shapes

Ages 7-8: Year 3

In Year 3, children extend their number work to three-digit numbers and begin to use formal written methods for addition and subtraction. Times tables practice becomes a daily focus.

Key milestones:

• Count from zero in multiples of 4, 8, 50, and 100
• Recognise place value in three-digit numbers
• Add and subtract numbers with up to three digits using column methods
• Recall and use multiplication and division facts for the 3, 4, and 8 times tables
• Solve problems involving multiplication and division
• Recognise and use fractions including tenths
• Tell and write the time using 12-hour and 24-hour clocks
• Measure and calculate perimeter

Ages 8-9: Year 4

Year 4 introduces larger numbers and more complex calculations. Children work with numbers up to 10,000 and tackle all times tables up to 12 × 12. Decimal notation appears for the first time.

Key milestones:

• Count in multiples of 6, 7, 9, 25, and 1,000
• Understand place value in four-digit numbers
• Add and subtract numbers with up to four digits
• Recall all multiplication and division facts up to 12 × 12
• Multiply two-digit and three-digit numbers by a one-digit number
• Recognise and write decimal equivalents of tenths and hundredths
• Convert between different units of measure
• Calculate area by counting squares

Ages 9-10: Year 5

Year 5 children work with increasingly large numbers (up to 1,000,000) and develop fluency with all four operations. Fractions, decimals, and percentages become interconnected.

Key milestones:

• Read, write, and order numbers to at least 1,000,000
• Add and subtract whole numbers with more than four digits
• Multiply and divide numbers mentally
• Multiply numbers up to four digits by a two-digit number
• Divide numbers up to four digits by a one-digit number
• Compare and order fractions with different denominators
• Understand percentages and their link to fractions and decimals
• Calculate perimeter and area of rectangles and composite shapes
• Measure and calculate angles

Ages 10-11: Year 6

In Year 6, children consolidate all their primary maths learning and prepare for secondary school. They work with multi-digit numbers, complex fractions, and solve multi-step problems across all areas of maths.

Key milestones:

• Read, write, order, and compare numbers up to 10,000,000
• Perform mental calculations with mixed operations
• Use long multiplication and division for larger numbers
• Add, subtract, multiply, and divide fractions
• Calculate percentages and use them to solve problems
• Work with ratio and proportion
• Solve problems involving the calculation of perimeter, area, and volume
• Use and interpret coordinates in all four quadrants
• Calculate with negative numbers

Supporting Your Child's Progress

Remember that these milestones are guidelines, not rigid requirements. Some children will race ahead in certain areas whilst needing more time in others. The key is to keep maths positive, practical, and connected to real life.

If your child seems to be struggling with a particular concept, try exploring it through games, visual aids, or everyday situations. Cooking, shopping, and telling the time all provide natural opportunities for maths practice without the pressure of formal learning.

Mathsonaut offers structured practice across all these year groups, from Reception through Year 6, with a space exploration theme that keeps children engaged. Each level builds on previous learning whilst introducing new concepts at just the right pace.
