Year 4

 

In Year 4 your child will be learning to :

  • Know the 2, 3, 4, 5, and 10 times tables by heart. For example, know facts such as 7 x 5 and 36 ÷ 4
  • Round three- digit numbers such as 672 to the nearest 10 or 100
  • Work out that a simple fraction such as 2/6 is equal to 1/3
  • Work our calculations in their head such as 26 + 58 and 62 – 37
  • Work out calculations by writing them in columns using pencil and paper such as 234 + 479 and 791 – 223
  • Multiply numbers such as 38 by 10 or 100, and divide numbers such as 4200 by 10 or 100.
  • Multiply and divide numbers up to 100 by 2, 3, 4 or 5 and find remainders, for example 36 x 3 or 87÷4
  • Change pounds to pence and metres to centimetres and vice versa, for example, work out that £3.45 is the same as 345p, and that 3.5 metres is the same as 350 centimetres.
  • Tell the time to the nearest minute and use a simple timetable.
  • Pick out shapes with similar features, for example, shapes with sides the same length, or with right angles, or symmetrical shapes.
  • Use +, -, x and ÷ to solve problems and decide whether it is best to calculate in her head or using paper and pencil.

 

Learning maths through money

Let your child use money and plan how to spend it.  Your child can also plan how to earn money.  When children use money their mental number work improves.

Learning maths while out and about

Your child can do maths while on the train, in a car or waiting for a bus.

Get back to 1

 You need a paper and pencil.

Together decide on a start number between 50 and 99.  Write the number down on a piece of paper.

When it is your turn, divide the number by 2, add the remainder to your answer and write down your new total.

Keep taking turns at working out the new total until someone writes 1.  This person is the winner.

Play the game again using a different start number or a different number to divide by.

Flexibility with numbers

Choose the first five digits you see, on buses, in shop windows, front doors and so on.  Try to use those five digits to make 50 by adding, subtracting, dividing or multiplying.

**I saw a 6, a 2, two 5s and a 9.  I can do 5 x 5 to get 25, then 25 x 2 to get 50.

Doubling and halving.

Doubling and halving are very useful skills and people who are fast at mental maths make great use of them.  Your child can practise by choosing a bus number, a price in a shop window, or a car number plate and doubling it or halving is in his head.

 

Helping children with their tables.

Your child will be familiar with the 2 times, 3 times, 4 times, 5 times and 10 times tables.  At school they will be learning the 6 times, 7 times, 8 times and 9 times tables.

Once you know the first few tables, you actually know more than you think.  For example, if you know ‘five eights’ you also know ‘eight fives’ This only leaves six difficult ones to learn.

You can help your child memorise these one at a time

6×6 = 36

6×7 = 42 (and 7×6 = 42)

7×7 = 49

6×8 = 48 (and 8×6 = 48)

7×8 = 56 (and 8×6= 56)

8×8 = 64

Rhymes

Help children to learn their tables facts by making up rhymes to go with the numbers they find hard to remember.

Playing games

Play board games such as Monopoly or Risk, or card games that involve scoring.
