Welcome to Year 3/4
Mathematics Update
Monday 23rd November 2015
The New Curriculum

The curriculum changed in September 2014

Lots of things moved into a new year group (what was taught in year 4 is now
taught in year 3 e.t.c.)

More focus on mental and written calculation and recall of facts (times tables
and number bond)

New focus on ‘mastery’ which means being able to apply knowledge in
problem solving.
Times tables in Year 3

By the end of Year 3 all children should know:

2x, 5x, and 10x (taught in year 2)

3x, 4x and 8x (8x is new to year 3)

They should also know the division facts for these times tables.

They should also be able to count in steps of: 50 and 100.
Times tables in year 4

By the end of Year 4 all children should know:

All their multiplication facts up to 12x12

(2x, 5x and 10x from year 2, 3x, 4x,and 8x from year 3, 6x, 7x, 9x, 11x and
12x in year 4)

They should also know all corresponding division facts for all the times tables.

They should also be able to count in steps of: 25 and 1000
Number Bonds

By the end of year 3:

Be confident with bonds (addition and subtraction) to 10, 20 and 100. (Taught
in year 2).

E.G:

7+3=10

17+3=20

70+30=100
Mental Calculation in Year 3

Finding 10 and 100 more/less (100 square to support)

Add and subtract 9 or 19 to a number (blank number lines)

63+19= 82
+20
-1
63

Doubling numbers (partitioning)

24+24

20+20=40

4+4=8

40+8=48
82 83
Mental Calculation Year 4

Find 1000 more/less than a given number (use previous knowledge)

Securing strategies from year 3, choosing the best strategy to use.
Written Methods in Year 3

Begin to use the column method for addition and subtraction

(3 digit number by 1 digit, 2 digit then 3 digit numbers)

Begin to use grid method for multiplication

(2 digit by 1 digit)

Introduction to bus stop method (may use chunking)

(2 digit by 1 digit)
Column addition and subtraction
Multiplication and Division
Written methods in Year 4

Formal written methods:

Column methods for addition and subtraction.

(numbers up to 4 digits)

Introduction to long multiplication methods

(2 digit by 1 digit, 3 digit by 1 digit)

Introduction to the bus stop method (including remainders)

(3 digit by 1 digit)
Addition and Subtraction
Multiplication and Division
Equipment we use in school

Counters,

Number cards,

Bead strings,

Number lines,

100 squares,

Multiplication girds,
Problem Solving
Do you really understand?

Going for mastery level means understanding what you are learning.

12x3=36 (or 27x4= 108)

Mrs Walker bought 12 (27) bunches of bananas, there were 3 (4) bananas on each
bunch. How many bananas were there altogether?

Can you write your own times table problem?

The answer is 842. Write 4 different addition calculations where this is the answer.

SATS (not as far away as you might think) now has 1 calculation paper and one
problem solving paper.
Explaining, Reasoning and Talking about
Maths

We will often ask how did you do that calculation (we often get my brain did
it!)

If children can explain and model a method it is another way of showing they
fully understand.

Peer support (let me tell you, show you, help you).

Try this at home
Maths at Home

Out and about: talk about things you see (shapes, colours, numbers, groups of
items, shopping lists, prices, special offers, timetables for buses and trains)

At home: play number games (snakes and ladders, counting toys by grouping,
dividing/sharing toys, cooking (measuring), how long can you?, you have __to
play on the computer! You can go on the computer at 11’o’clock).

On the Computer:

Purple Mash (table toons and other activities)
