St Bernadette Catholic Primary School Maths Parent Workshop Wednesday 26 th June 2012 “learning to grow in knowledge, faith and love through friendship with Jesus and Mary“,

Aims To explain how we teach your children +, -, x and ÷. To give you ideas of how you can help your children at home.

How did you solve these? = = 46x22= 154÷7=

Maths lessons Emphasis on mental calculation Children are encouraged to work mentally, using jottings to support their thinking Encouraged to use more formal written methods only for calculations they can not solve in their heads Maths through problem solving

By the end of Key Stage 2 we want your children to… Recall key number facts eg number bonds to 10 and associated bonds to 100. Have good understanding of the 4 operations Have an efficient, reliable method of calculation for each operation Apply what they know Use a calculator effectively

Addition

Adding Practically

Addition Encouraging children to put the biggest number in their head and count on

Use of a number line Addition 6+5= Use of a 100 square 34+12=

Partitioning

Addition by partitioning =

Addition by partitioning = Your Turn 56+43=

Addition using a blank number line 45+34= Your Turn! =

Addition = The Extended Method Your turn =

Addition- Standard Written Method =

Subtraction

3-2= Taking away practically.

Use of a number line/100 square 12-6=

Subtraction using a blank number line 62 – 26 = Your turn! 78-44=

Subtraction 654 – 96 = (to make 100) 500 (to make 600) 54 (to make 654) 558 Add on to 96 the number that makes 100 Add on to 100 the number that makes 600 Add on to 600 the number that makes 654 Relates to the number line method as follows =558

Subtraction- Standard Written Method = = = = 305

Multiplication

Multiplication- repeated addition xx x 3x5= (3 groups of 5) xx x xx x = 15

Multiplication using a blank number line 4x3= Your turn - 6x8=

Times tables By end of Year 2 children should know x2,x5,x10 Practise counting in 2’s, 3’s, 4’s, 5’s, 10’s Matching pairs (question on one card, answer on another) Musical times tables

Multiplication by partitioning 32x3= Your turn - 45x6=

Grid Method 32x7= 33x22= Your turn! - 34x23=

Multiplication-Standard Written Method 352x27= 352 x (352x7) 7040 (352x20)

Division ÷

Sharing The children are sharing out into a known number of groups but how many in each group is unknown, 12÷3= 12 apples are shared into 3 baskets. How many apples are in each basket? ÷

Division Grouping It is known how many are in a group but the number of groups is not known. 12÷3= How many groups of 3 are there in 12? There are 12 apples. How many horses will get 3? ÷

Division using a blank number line 25÷5= 5 (How many groups of 5 are there in 25?) ÷ Your turn - 24÷6

Division- Chunking 96÷6= Fact Box 1x6=6 2x6=12 5x6=30 10x6=60 20x6=120 50x6= x6=600 (How many groups of 6 are there in 96?)

Your Turn! Fact Box 1 x 9 = 9 2 x 9 = 18 5 x 9 = x 9 = x 9 = x 9 = x 9 = ÷9=58

Your Turn! Fact Box 1 x 7 = 7 2 x 7 = 14 5 x 7 = x 7 = x 7 = x 7 = x 7 = ÷7=

How you can support your child Look for and talk about numbers in the environment Play games Shopping Counting on/back Number bonds Doubles/Halves Times tables Division facts
