Session 1 – Key Features Of Maths

Maths Is Fun! What makes for a good maths lesson? (discussion)

Playing board for the game Crooked Rules
Hundreds Tens Ones Player A Player B Player C Player D Note: die = singular, dice = plural No die? Why not number some blank playing cards. Then you could go 0 to 9. Anyone got Spin To Win? Primary Games volume 1, (www.primarygames.co.uk)

Key features of mathematics within the Primary National Strategy
The strategy involves: 1. A structured, daily mathematics lesson of 45–60 minutes, depending on the pupils’ ages 2. An emphasis on mental calculation with oral and mental work in each lesson 3. Direct, interactive teaching of the whole class, with as many pupils as possible taking part 4. Group work in which pupils in three or four groups work at different levels on the same topic 5. Regular activities for pupils to do out of class and at home 6. The Primary Framework offers teachers guidance on planning and teaching to help all children to learn mathematics and make good progress.

Key Strategies for Mental Calculations
Number Bonds And Compliments These are essential facts for children to know. + = = 7 3 + 4 This is an example of a number bond. If given the number 7 the child needs to identify two numbers which would add to give the target number. Bonds of ALL numbers up to 20 is a key skill to be mastered by the end of Year 2.

Key Strategies for Mental Calculations
Number Bonds And Compliments ? + = = 7 3 + This is an example of a number compliment. If given the total 7 and one number, state the other which adds to make the targe total.

Key Strategies for Mental Calculations
+ = 13 Show how many are in one hand; how many must now be in the other? (Consider ‘What’s In The Box’ game + = 13

Lets play this game for a few minutes in small groups.
Race To 100 This is a two player game. The aim is to be the first player to take the running total to 100 or above. Players take it in turns choosing numbers from 1 to 10. Here is an example: Player 1 chooses 7 running total is 7 Player 2 chooses 4 running total is 11 Player 1 chooses 10 running total is 21 Player 2 chooses 3 running total is 24 Lets play this game for a few minutes in small groups.

Shut The Box Two dice are rolled and added.
Any combination of numbers can be ‘shut’ providing they equal the total of both dice. Play continues until no further numbers can be ‘shut’. This becomes the player’s score for their first go and play transfers to another player. This is a negative scoring game. Hence the first player to reach 50 LOSES. If the box is successfully ‘shut’ then the player who shut the box wins that game irrespective of the scores.

I Am Thinking Of A Number
I am thinking of a number between 0 and 10,000. Each time you guess I will tell you if you are too high or too low. You have 14 guesses.

Lets play this game for a few minutes in small groups.
The Kidney Bean Game There are 35 kidney beans in a pot. Players take it in turns to take kidney beans out of the pot. You can take 1, 2, 3, 4 or 5 kidney beans at a time. THE WINNER IS THE PLAYER WHO TAKES THE LAST HANDFUL AND LEAVES THE POT EMPTY. Lets play this game for a few minutes in small groups.

In The Middle How would you find the middle number in between 45 and 73? Most people would find the difference, halve that difference and add it to the lower number. But this would work and is often quicker: then halve the result.

Tables Number Lines Tables recall is very important.
Counting using a number line is a great way to develop tables rapid recall. This number line shows the 7 times table: 1 2 3 4 5 6 7 8 9 10 7 14 21 28 35 42 49 56 63 70

Jigsaws Lets have a go at one….

Session 2 – Approaches To Calculation: Mental And Written
and God said….. ……and there was light.

How would you tackle these calculations?
1). 23 – 9 2). 127 x 6 3) 4). 98 ÷ 6 5) 6) 7) 8). £ £ £1.46

Considering how you did the calculations
How did you work out each calculation? Who did it another way? Which is the easiest way? What did you jot down to help you? How did this help and how might you encourage pupils to use jottings?

Comparing methods Were you surprised by any of the methods others used? Were you taught to use any of these methods at school? Why do you think you use them now? Did having to explain your method help you in any way Did hearing any other person’s method help you in any way?

Try this one… 365 – 99 ___ 365 – 99

Key skills to develop Rapid recall of bonds and complements.
Addition and subtraction by rounding and adjusting. Rapid recall of tables facts. Rapid recall of division facts which correspond to tables facts. Ability to complete division with remainders using numbers within the range of the tables recall. Halving by partitioning and combining; halving of values where the digit itself is ‘odd’ including amounts of money. Writing numbers in digits when read aloud with a focus on zero as place holder.

Written Methods T.A.s have asked for upskilling on written methods. We will now take some time to look at: Addition from number line to columns Subtraction methods: number line expanded subtraction compact ‘borrowing’ Written multiplication ~ TU x U to TU x TU Written division ~ what have you seen going on? You can have such an impact by suggesting to a teacher ‘I saw this bloke called Ed doing this….’

Subtraction Subtraction begins by children literally taking away with objects. This then progresses to counting backwards on the number line. FIND THE DIFFERENCE SHOULD BE INTRODUCED HERE! Children SHOULD then progress to counting FORWARD on the number line.

Subtraction Using objects. take away makes

Subtraction Number Line “What is 23 take away 8?” -1 -1 -1 -1 -1 -1 -1
15 16 17 18 19 20 21 22 23

Subtraction Number Line Stage 2 “What is 23 take away 8?” -5 -3 15 16
17 18 19 20 21 22 23

Subtract 9 strategy often gets confused with subtract 11 strategy.
Subtraction Number Line Stage Subtract 8 or 9 “What is 23 take away 8?” +2 -10 13 14 15 16 17 18 19 20 21 22 23 Subtract 9 strategy often gets confused with subtract 11 strategy.

Subtraction Number Line Going Forward “What is 572 take away 238?” 238
240 250 260 270 280 290 300 etc etc 572

Subtraction Number Line Going Forward “What is 572 take away 238?”
+200 +72 +2 +60 238 240 300 500 572 Now add the jumps It’s easiest to consider

Subtraction Write The Landing Numbers First
“What is 5271 take away 2638?” 2638 2640 2700 3000 5000 5271

Subtraction Then Write In The Jumps “What is 5271 take away 2638?”
+2000 +271 +300 +2 +60 2638 2640 2700 3000 5000 5271 Now add the jumps. It is quite easy to add the first 4. This leaves Now lets do some!

Subtraction The Equals Sign
Children tend to be taught that the answer goes after the equals sign. They can do this: 12 – 7 = But not this 7 = 12 - Have a go at the empty box sum questions.

Multiplication Multiplication Begin with rapid tables recall.
Then informal partitioning or use of a grid: To solve 47 x 6: 6 6 240 42 Answer = 282

Multiplication Classic Error
Then when faced with a question like this: 37 x 25 Children will do 30 x 20 and 7 x 5 This is WRONG. (but they often cannot see why) The sum 37 x 25 would need a grid like this: Can you see why this proves 30 x 20 and 7 x 5 is incorrect?

Multiplication Proof 30 7 20 600 140 Adding these four values gives the answer 925 150 35 5 It is within this type of question that the ‘add zero’ rule can pop up.

Multiplication Errors Question 1: 78 x 96 Question 2: 63 x 54
Question 2 will cause more errors than question 1. Why do you think this is?

Division Sharing Or Grouping
These tend to be the classic early models of division. They are slightly different. I will model the difference on the flip chart.

Division Sharing With Objects, Grouping With Cups
It can help for children’s general development to experience both models of early division. Sharing can be easily be modelled with counters, sweets and the like.

Division Sharing With Objects
It can help for children’s general development to experience both models of early division. Sharing can be easily be modelled with counters, sweets and the like. For example: 32 ÷ 6.

Division Grouping With Cups
This involves how many groups of the divisor can be made. For example: 32 ÷ 6. (This is best done with a practical model)

Division ‘Old Method’ v ‘Chunking’ This is more top end KS2.
Take some time now to consider some children you work with. Are there any tips, hints or strategies here you could take back to the classroom? Is there anything here which you could share with your teacher(s) or even the whole staff? If anyone wants to talk about more formal division I will do this in small groups or individually.

Session 3 – Language And Maths

Work out the total number of shapes:

Circle = 1 Rectangles = 4 Triangles = 5 Squares = 9 TOTAL = 19
Work out the total Circle = 1 Rectangles = 4 Triangles = 5 Squares = 9 TOTAL = 19

Work out the total 15

Ellie’s problem In your purse you have lots of 5p, 10p and 20p coins.
How could you pay for some fruit costing 45p?

Ed’s Classroom Danielle working on 428 – 379 We were using the number line as our primary strategy. Danielle had the correct answer. She, however, said this: “I took the 300 away from 400”. I then got a bit worried. She carried on. She struggled to explain but in the end we figured out she had turned 428 – 379 into

Marie’s sum + 47 = 100 This is the calculation Marie was asked to do:
She wrote: = 100 Do you find that sometimes children cannot spot an error? Get some coins / a calculator to ‘prove’ it Suggest the child makes up some of their own – what do they notice? (‘tens’ values add to 90).

Closed To Open ~ Shapes C A B D E

Closed To Open ~ Number Write down a multiple of 5.
Write down a multiple of 5 that is bigger than 20. Write down a multiple of 5 that is bigger than 20 and is also a multiple of 7. Write down a multiple of 5 that is bigger than 20, that is also a multiple of 7 and is even. Write down a multiple of 5 that is bigger than 20, that is also a multiple of 7, that is even and is not a multiple of 10.

You could do things like this:
6 2 > 3 8

Or this… 1 2 < 2 1

Or maybe even this… 3 x 8 = 6 x ? 9 - 2 = ? + 3

Language and mathematics
Pupils talking and listening to each other and to adults Adults listening to pupils’ responses Different kinds of questioning Video clip; x 10 x 100 How could the TA have been better briefed and equipped to help?

Four In A Row Rules: Make one of the numbers on the playing board using the numbers 1, 2, 3, 4 and the symbols +, x, ÷, -, and brackets. Each number MUST be used once and once only.

Fall In The Water Rules:
Choose what numbers between 1 and 20 (or 30 / 40 / 50 etc) will make you ‘fall in the water’ Take it in turns to roll the die and add to your own running total. If you fall in the water you start again at zero.

Poker Cups Rules: Each poker chip is worth a different value (these values can be changed) Keep a track of the running total in cup A, cup B or BOTH cups if you are really brave! 3 5 7 8

Sessions 6 – Quick Activities
We will have a go at a couple of quick, meaningful ‘time-fillers’. Along with these are some useful websites:
