What Should a Child Know in Year 2 Maths?

Year 2 is a significant milestone in UK primary education. Children aged 6–7 complete Key Stage 1, and at the end of the year they sit the KS1 SATs — assessments in reading, maths, and writing. Understanding what is expected in Year 2 maths can help you support your child with confidence.

Number and Place Value

Year 2 pupils extend their number knowledge significantly. They work with numbers up to 100 and are expected to:

• Recognise the place value of each digit in a two-digit number (tens and ones)
• Read and write numbers to at least 100 in numerals and in words
• Compare and order numbers from 0 to 100 using <, >, and = signs
• Count in steps of 2, 3, and 5 from 0
• Identify, represent, and estimate numbers on a number line

Addition and Subtraction

Arithmetic in Year 2 becomes more demanding. Children should be able to:

• Add and subtract numbers using concrete objects, pictorial representations, and mental methods
• Add and subtract two-digit numbers and ones; two-digit numbers and tens
• Recall and use addition and subtraction facts to 20 fluently
• Recognise and use the inverse relationship between addition and subtraction
• Solve problems with addition and subtraction using up to two steps

The move from concrete objects (using counters, number lines) to mental strategies is a key progression in Year 2. Some children make this jump confidently; others need more time with physical resources — both are completely normal.

Multiplication and Division

Year 2 introduces formal multiplication and division. Children are expected to learn their 2, 5, and 10 times tables and be able to:

• Calculate mathematical statements for multiplication and division
• Show that multiplication of two numbers can be done in any order (commutativity)
• Solve problems involving multiplication and division, using materials, arrays, and mental methods

The 10 times table is usually the easiest to learn first (just add a zero), followed by the 5s (all end in 0 or 5), then the 2s. Short, daily repetition is the most reliable way to build recall.

Fractions

Fractions in Year 2 go beyond simple halves and quarters. Children learn to:

• Recognise, find, name, and write fractions ⅓, ¼, 2⁄4, and ¾ of a length, shape, set of objects, or quantity
• Write simple fractions (e.g. ½ of 6 = 3)
• Recognise the equivalence of 2⁄4 and ½

Measurement, Geometry and Statistics

Year 2 also covers a broad range of practical maths topics:

• Measurement: choosing appropriate units, reading scales, using rulers. Also money (recognising coins/notes, combining values) and time (telling to the nearest 5 minutes, using a.m. and p.m.)
• Geometry: identifying 2D and 3D shapes, describing their properties, ordering and arranging combinations of mathematical objects, using mathematical vocabulary to describe position and direction
• Statistics: interpreting and constructing simple pictograms, tally charts, block diagrams, and tables
