Maths What does Maths mean

Maths • What does Maths mean to you? • When do we use it?

What Maths Means To Us! • At Churchdown Village Infant School we teach Maths so that every child will have confidence and a secure understanding of mathematics. • We believe that this enables a solid base which will develop into life long skills.

How We Teach For Progression We teach the children: • to recognise numbers and know their value • money • calculation • mathematical language • shape, space and measure

Reception – Year 2 • • • We teach the children 4 Basic Operations Add Subtract Multiply Divide All 4 operations are taught mainly through exploration e. g. playing games, posing practical problems based on real life situations.

Through: • play based activities : • oral counting • action rhymes & songs • stories • ICT games • Exploration

Mathematical Language We believe that one way to break down barriers which prevent learning in maths is to focus on mathematical language whilst also teaching the basic skills. NCETM (National Centre for Excellence in Teaching Mathematics)

Y 1 & Y 2 Number lines If there are 25 cars in a car park and 12 more cars drive in how many cars will be in the car park? 25 + 12 = +10 25 +2 35 37

Year 2 Bridging the Tens Number line I save 16 p and dad gives me 68 p more for doing jobs. How much will I have now? 16 p+ 68 p= 68 p+16 p= +10 p 68 p +6 p 78 p 84 p

Y 1 & Y 2 Partitioning to Double What is double 12? 12+12= 10 +10 = 20 2+2=4 20 +4 =24

Y 2 Bridging the Ten by Partitioning There are 2 shelves on my book case. 45 books on the top shelf and 46 books on the bottom one. How many books are on my book case? 45+46= 40 +40 = 80 5 + 6 = 11 80 +11 =91

Remember to Multiply 5 children sit in groups of 4. How many children are there? Alex buys 5 packets of stickers. There are 5 stickers in each packet. How many stickers does Alex have altogether?

Doubling 2 lots of 3=6 2 x 3=6

YR-Y 2 Using Objects and Symbols 4 x 3 = 12

Y 1 -Y 2 Repeated Addition

Simple Arrays 3 x 5 = 15

Y 2 Arrays and Partitioning 4 x 13 4 x 10= 40 4 x 3 = 12 40+12=52

Remember to Divide There are 20 sweets in my bag and I have to share them equally with my sister! How many will we have each? Noah invites Max and Harry to play. He has 15 cars and he has to share them equally. How can he do this? How many cars will Noah have? How many cars will Harry and Max have? Is it fair?

Reception Using Pictures one for you & one for me 6 cakes shared between 2 = 3 6 ÷ 2 =3

Using Symbols to divide or finding a quarter 20 ÷ 4 = 5

Y 1&Y 2 Number lines (Repeated subtraction for division) 30 5 = 6 0 5 10 15 20 25 30

Y 2 Number lines (Repeated addition for division) 30 5 = 6 0 5 10 15 20 25 30
