Year 3


In Year 3 the focus is on mentally adding and subtracting numbers.  But maths also includes measuring, statistics and shape and space. 

In Year 3 your child will be learning to:

  • Read and write numbers up to 1000 and put them in order.
  • Know what each digit is worth in numbers up to 1000
  • Count on or back in tens or hundreds from any number under 1000, for example, ‘462, 472, 482…’ or 662, 562, 462…’
  • Know by heart addition and subtraction facts up to 20, for example, 4 + 16 = 20, 12 + 8 = 20.
  • Work calculations out in his head such as 56 +29 and 97 – 51.
  • Do simple division with remainders, such as 27 ÷ 5
  • Find simple fractions, such as ½ , ¹⁄3, ¼, ¹⁄5 or ¹⁄10 of shapes and numbers.
  • Tell the time to the nearest 5 minutes
  • Use £ and p, for example, know that £2.04 is £2 and 4p
  • Solve simple number problems and explain how to work them out.
  • Recognise right angles and lines of symmetry in simple shapes
  • Explain a simple graph.


Ways to help your child with maths

You can use a 100 square to help your child become confident with doing calculations in his head.

Things to do with a 100 Square

  • Read the numbers in order
  • Colour all the numbers in the 10 times table yellow (10, 20, 30, 40 and so on), then colour all the numbers in the 5 times table red (5, 10, 15, 20 and so on).  Why have the ‘tens’ numbers ended up orange.
  • Check the names of the numbers – **Is that number thirty four or forty three? [pointing to 34]
  • Count in tens starting at any number.  ** 14, 24, 34, 44, 54…
  • Use the grid whenever you are talking about numbers ** it’s Nan’s 56th birthday. Can you find her age on the grid?
  • Look for patterns and talk about them – ** Look at the numbers in that diagonal line: 10, 19, 28, 37, 46, 55, 64, 73, 82, 91. Each number is 9 more than the one before.

◊ Helps children gain confidence with numbers.


Initial the number

You need a pack of cards with the picture cards removed.

Turn the pack of cards face down.  Take turns to pick two cards and add their numbers together.  Then find two numbers on the 100 square whose difference is the same as your total.  Write your initial in those two squares.  The winner is the first person to write their initials in four squares in a line

Three in a line

You need two dice and coloured counters.

Take turns to roll dice and multiply the numbers together.  On the 100 square, cover your total with a counter.  The winner is the first person to get a line of 3 counters. (Remember you will only use some of the numbers up to 36)

◊ Helps children with their times tables.
