Maths Workshop for Parents

February 2018

The aim of today is to share the calculation methods we use at school so you are confident in supporting your child at home.

Aim

Developing Understanding

• Prompting thinking & questioning
• Providing opportunities to manipulate, experience

and see (use of resources)

• Develop thinking through investigation
• Reasoning and making connections
• Engaging in talk using mathematical vocabulary.
• Encouraging children to make links and generalise

Reception and KS1 Mental Arithmetic

The emphasis in Reception and KS1 is on mental arithmetic BUT based on practical activities using a range of equipment:

Resources

Working through calculations Concrete Pictorial Abstract

Using objects Using drawings

• r jottings

Using a written more formal method

Progression from Reception to Year 2 Addition

ELG  Count reliably from 1-20, place them in order.  Say which number is one more than a given number  Using quantities and objects, they add single-digit numbers and count

• n to find the answers

Year 1 - Addition

Year 1 Expectations  Count to and across 100, forwards beginning with 0 or 1, from any given number  Given a number, identify one more  Read, write and interpret mathematical statements involving addition (+), and equals (=) signs.  Represent and use number bonds and related subtraction facts within 20  Add one-digit and two-digit numbers to 20, including zero  Solve one-step problems that involve addition using concrete

• bjects and pictorial representations, and missing number problems

Year 2 - Addition

Year 2 Expectations  Recall and use addition and subtraction facts to 20 fluently, and derive and use related facts to 100.  Recognise and use the inverse relationship between addition and subtraction and use this to check calculations and solve missing number problems.  Add numbers using concrete objects, pictorial representations, and mentally, including:

• A two-digit number and ones
• A two-digit number and tens
• Two two-digit numbers
• Adding three one-digit numbers

 Solve problems with addition including those involving numbers, quantities and measures.

Addition strategies

Children are taught the rules of addition: Numbers can be added in any order The answer is always bigger then the numbers you are adding together

The column method is not introduced to children until Year 3.

Progression from Reception to Year 2 Subtraction

ELG  Say which number is one less than a given number.  Using quantities and objects, they subtract two single-digit numbers and count back to find the answers

Year 1 - Subtraction

Year 1 Expectations  Say which number is one less than a given number  Represent and use number bonds and related subtraction facts within 20  Read, write and interpret mathematical statements involving subtraction (-) and equals (=) signs  Subtract one-digit and two-digit numbers to 20, including zero  Solve one-step problems that involve subtraction using concrete

• bjects and pictorial representations, and missing number

problems.

Year 2 - Subtraction

Year 2 Expectations  Recall and use subtraction facts to 20 fluently, and derive and use related facts to 100.  Recognise and use the inverse relationship between addition and subtraction and use this to check calculations and solve missing number problems.  Subtract numbers using concrete objects, pictorial representations, and mentally, including:

• A two-digit number and ones
• A two-digit number and tens
• Two two-digit numbers

Subtraction strategies

Children are taught the rules of subtraction: The first number always has to go first The answer is always smaller then the numbers you are subtracting

‘Put 16 in your head and count back 4’

The column method is not introduced to children until Year 3.

Multiplication

Multiplication – Year 1 Solve one-step problems involving multiplication by calculating the answer using concrete objects, pictorial representations and arrays with the support of the teacher Count in multiples of twos, fives and tens Recall doubles of all numbers to at least 10 Multiplication - Early Years (EYFS) Children will continue to engage in a wide variety of songs and rhymes, games and

• activities. In practical activities and

through discussion they will begin to solve problems involving doubling.

Multiplication and Division

Multiplication – Year 2

• Recall and use multiplication and division facts for the 2, 5 and 10

multiplication tables

• Calculate mathematical statements for multiplication and division
• Show that multiplication can be done in any order
• Solve problems using multiplication and division

How can you help at home?

• Remain positive and be enthusiastic about

maths

• Point out the maths in everyday
• life. Include your child in activities

involving maths such as using money, cooking and travelling.

• Play simple maths games and help develop

strong number knowledge

• Number recognition, formation, counting

forwards and backwards and in steps of 2, 3s (Year 2), 5s and 10s.

• Number bond recal
