**Year 3 Maths facts**

**1.** Know all addition and subtraction facts to 20 (including number bonds)

**2.** Know all multiples of 10 and 5 which add to make 100 (e.g 5 + 95, 10 + 90)

**3.** Know all doubles and halves to 20.

**4.** Know all multiplication and division facts for the 2,3,4,5,6 and 10 times tables.

**5.** Know that < means less than and > means greater than

**6.** Know that a multiple is the answer when one number is multiplied (X) by another (24 is a multiple of 4 and 6 because 6 X 4= 24).

**7.** Know that a factor of a number is a number that divides exactly into another number without remainders (4 and 5 are factors of 20 because 20 divided by 4 is 5)

**Understanding shape**

**8.** Know the names of these 2D shapes:

Circle- A continuous line goes around the edge, always the same distance from the centre.

Triangle- 3-sided shape

Square- a 4-sided shape with equal length sides

Rectangle- a 4-sided shape which has 2 pairs of equal length sides

Quadrilateral- a 4-sided shape

Pentagon- a 5-sided shape,

Hexagon- a 6-sided shape

Octagon- an 8-sided shape

**9.** Know the names and properties of these 3D shapes:

Prism- Two identical parallel sides-all the rest are rectangles.

Cube- six square faces

Cuboid- six rectangular faces

Pyramid- Triangular faces moving to a point (vertex). Can have different shaped bases.

Sphere- A ball

Cone- a circular pyramid

Cylinder- a circular prism

**10.** Know the direction of the compass points North, South, East and West.

**Measuring**

**11.** Know that: 60 seconds = 1 minute

60 minutes = 1 hour

24 hours = 1 day

7 days = 1 week

14 days = 1 fortnight

52 weeks = 1 year

12 months = 1 year

100 years = 1 century

**12.** Know how many days there are in each month

**13.** Know that AM refers to times in the morning, from midnight to midday and PM refers to times in the afternoon from midday to midnight.

**14.** Know that 1000 metres = 1kilometre, 100 centimetres = 1 Metre, 1000 grams = 1 kilogram and 1000 millilitres = 1 Litre

**EXPLANATION AND IDEAS FOR LEARNING**

Number Bonds: Pairs which make up a number. The number bonds for ten, for instance, are: 0+10, 1+9, 2+8, 3+7, 4+6, 5+5. These are useful in all areas of maths!

Games:PING PONG- Start off saying 'ping' and the child replies with 'pong'. Repeat/reverse, and then convert to maths facts, i.e. say '2' and they reply '8' if doing number bonds to 10. This can also be used for doubling and halving (e.g. double 4: 8, half of 8: 4).

> < Greater than/ Less than

A great way to remember these is

to think of them as arrows and the

bigger number always points to the

smaller one.

Multiplication and division facts: When children learn a times tables fact such as 4 X 5=20 they also know the associated division fact: 20 ÷ 4= 5.

Memory tricks-

Make up rhymes for tables that children frequently forget. For example: 8 X 3= Aliens at the door- 24.

Actions to go with tables facts 'Eight eights are sixty four, clap, clap, knock on the floor.'

Use an ordinary pack of playing cards!

A great way to practise table facts is to share out playing cards between you and your child. Both turn a card over and the quickest one to multiply the numbers keeps the cards. The winner is the person with the most cards.

This can also be used for addition to 20- the quickest to add the numbers keeps the cards and subtraction- the quickest to take away the smaller number from the larger number.
