# KS2 Mathematics Parent Workshop November 2015 Mrs Adrien

KS2 Mathematics Parent Workshop November 2015 Mrs Adrien Assistant Head of Teaching and Learning Miss Campbell Head of Maths Contents - The New Curriculum whats new in Key Stage 2 - Addition and subtraction including calculation methods and progression

- Mental Mathematics - End of Year Expectations - Your turn to have a go/Using and Applying - Year 6 SATS - Problem Solving - How you can help at home - Online applications Aims

- Enable you to understand the changes occurring in mathematics due to the new curriculum - Provide you with a greater understanding of how mathematics is taught in school and progression of addition and subtraction through Key Stage 2. - Enable you to see the types of different questions children are asked in their assessments. - See the importance of mental mathematical skills and the strategies children are taught. - Help you understand how you can help your child at

home. The New Curriculum - More cross curricular -Greater links with Computing -In each year group the expectations are higher -Problem Solving no longer taught discretely but embedded within each area/domain of mathematics -Divided into Lower Key Stage 2 and Upper Key Stage 2 -The 2016 assessment tests will be based on the new

curriculum content The New Curriculum New Expectations By the end of year 4 pupils should -memorise their multiplication tables up to and including the 12 times table -show precision and fluency in their work By the end of year 6 pupils should - Be fluent in written methods for all four operations,

including long multiplication and division, and in working with fractions, decimals and percentages. -Pupils should read, spell and pronounce mathematical vocabulary correctly. Addition and Subtraction Calculation Methods and Progression The 4 operations Why so many methods?

- Children are entitled to be taught and to acquire secure mental methods and efficient written methods of calculation for each operation which they know they can rely on when mental methods are not appropriate. We teach them a range so they can choose the one they prefer and proves most accurate for them. Addition Addition Lower KS2 Number Lines:

Addition Addition Lower KS2 Partitioning: Partitioning means splitting the number into the tens and units. 48 + 36 = 40 + 30 = 70

40 + 8 8 + 6 = 14 30 + 6 = 84 70 + 14 = 84

Addition Addition Lower KS2 Expanded methods in columns: Childrens understanding of place value has to be secure. 48 + 36 = 84 48 36+ 1 4 adding units first 7 0 adding tens 84

Addition Addition Upper KS2 Column Method: This method remains efficient when adding larger numbers and decimals. It is a quick and reliable method. 48 + 36 = 84 48 36+ 84

1 carrying ten Addition Addition Upper KS2 - Column Method This method remains efficient when adding larger numbers and decimals. It is a quick and reliable method. 379 + 92 = 471 379 92+

471 1 1 carrying ten and one hundred Addition Here are five digit cards. 1

2 3 4 Use all five digit cards once to make this sum correct. + 6 0

5 Addition 1) Calculate 1202 + 45 + 367 2) Calculate 8.52 7.78 3) Write in the missing digits. Subtraction Subtraction Lower KS2

Counting On Finding the difference -Count on from the smallest to the largest once again bridging through ten or a multiple of ten. + 30 +4 +2 38

40 74 38 = (2 + 30 + 4) = 36 70 74 Subtraction Subtraction Lower KS2

Partitioning: Subtraction Subtraction Lower KS2 Partitioning: Subtraction Subtraction Lower & Upper KS2 Column Method Decomposition:

153 Subtraction Subtraction Upper KS2 Subtraction Now its your turn! Liam spends 14 altogether on the Big Wheel and the Rollercoaster.

He goes on the Big Wheel twice. How many times does he go on the Rollercoaster? Level 4 Questions The Four Operations Now its your turn! Dev and Joe each buy a book.

Dev pays with a 5 note and gets 1.05 change. Joes book costs 7 How much more does Joes book cost than Devs book? Level 4 Questions Mental Mathematics It is essential children have secure knowledge and recall of mental facts including: -Place Value including decimals

-Number bonds -Times tables from 0 to 12! -Corresponding division facts -Rounding to enable estimation of answers Mental Mathematics Mental Mathematic Strategies: -Use number bonds to 10, 20 and 100 transferable to 1,000 and decimals -Multiplication and division by 10, 100, 1,000, 0.1

-Use doubles and near doubles -Partition into thousands, hundreds, tens and units -Adding near multiples of 10. Adding the multiple then add or subtract 1 -Subtracting near multiples of 10. Subtracting the multiple then subtracting or adding 1. -These are transferable to multiples of 100, 1,000 etc. Problem Solving Using and applying knowledge and skills

Explaining, Reasoning & Justifying Now its your turn! Three whole numbers add up to 50 Seb says,All three numbers must be even numbers. Is Seb correct? Circle Yes or No. Yes / No Explain how you know.

Level 5 Questions Level 6 SATS Now its your turn! Find the value of t in this equation. 33 8t = 15 Level 6 Questions Level 6 SATS

Level 6 Questions How you can help at home Handout on webpage Maths vocab on webpage Any other questions? Thank you
