Parent Workshop Mathematics

Aims: - To demonstrate how we teach Mathematics in Reception to Year 2 - To allow time for you to play with some of the resources we use - Give you some ideas of games/resources you can play with at home

Addition +

Reception ~ Using quantities & objects add two single-digit numbers ~ Count on back to find an answer

Using numicon demonstrate how you would solve the following question; Year 1 ~ Addition with numbers up to 20 5 + 3 = Using numicon demonstrate how you would solve the following question; 7+4 = Focus on counting to 20 in yr1 although ch. Need to work with numbers up to 100 by the end of the yr. Pratically – moving the objects and being able to count on – 3 ….4, 5 etc Finding number bonds to a number – can you make number bonds to 8 using the nuimcon Using numicon to add simple additions – discuss bridging the 10 Numberline – counting on

Using base 10 demonstrate how you would solve the following question; Year 2 ~ Addition with two digit numbers 34 + 11 = Using base 10 demonstrate how you would solve the following question; 42 +23 = By counting on a ten and adding a one

Year 2 34 + 13 = ~ Addition with two digit numbers Add by partitioning on a blank number line…. Practise 10 more lots before we move on to partitioning numbers Show on board

Year 2 ~ Addition with two digit numbers using column addition 34 + 27 = T O 4 2 7 + Better as only adding 1 digit essentially - understanding needs to be secure of tens and ones Carrying the 10

Subtraction -

Reception ~ Using quantities & objects subtract two single-digit numbers ~ Count back to find an answer Numicon picture Real objects 1 less

Using numicon demonstrate how you would solve the following question; Year 1 ~ Subtraction with numbers up to 20 Using numicon demonstrate how you would solve the following question; 8-3 = Numicon – how we use it – show on board Using concrete resources Taking physical resources away 13 – 5 =

Year 2 34 - 11 = ~ Subtraction with two digit numbers By taking a ten away and taking a one away

Year 2 34 - 13 = ~ Subtraction with two digit numbers Subtract by partitioning on a blank number line…. Practise 10 more lots before we move on to partitioning numbers Show on board

Year 2 ~Subtraction with two digit numbers using column subtraction 34 - 27 = T O 4 2 7 - Better as only adding 1 digit essentially - understanding needs to be secure of tens and ones Carrying the 10

Multiplication x

Reception ~ Solve problems involving doubling ~ Solve practical problems involve combining groups of 2, 5 or 10 Numicon picture

Using numicon demonstrate how you would solve the following question; Year 1 ~ Multiply using concrete objects, pictorial representations and arrays with the support of the teacher 2 + 2 + 2 = Using numicon demonstrate how you would solve the following question; 2 + 2 + 2 +2 = Massive focus on doubles and halves and children need to be able to count in 2’s, 5’s and 10’s Doubles + = 4

Using numicon demonstrate how you would solve the following question; Year 2 ~ Multiply using arrays and repeated addition (2’s, 5’s & 10’s) Repeated addition – using concrete apparatus, numicon, on a number line & a bead bar Using numicon demonstrate how you would solve the following question; 5 x 3 = Commutativity - array 5 times 3 ~ 5 + 5 +5 = 15 3 lots of 5 ~ 3 x 5 5 x 3 is the same as 3 x 5

Division ÷

Reception ~ Solve problems including halving & sharing ~ Solve practical problems that involve sharing groups of 2, 5, 10 into equal groups Numicon picture Practical object picture

Using objects demonstrate how you would solve the following question; Year 1 ~ Grouping & sharing in small quantities 6 ÷ 2 = Using objects demonstrate how you would solve the following question; 8 ÷ 2 = Equal groups Sharing items during play & problem solving Show numicon – placing tiles of 2 on a 6 tile Number line - show Numicon Repeated subtraction on number line

Solve this problem on a number line: Share 8 sweets between 2 people. Year 2 ~ Calculate mathematical statements for division & write them using division (÷) and equals (=) Sharing equally – children will develop their own ways of jotting Repeated subtraction – using a number line Solve this problem on a number line: Share 8 sweets between 2 people. 5 times 3 ~ 5 + 5 +5 = 15 3 lots of 5 ~ 3 x 5
