  1. Year 3 words • Lots of • Multiply • Twice • Five times • Long, wide • and so on • Array left • Column • Divided by • Halve • Groups of • Multiplied by • three • Ten times . . • Left over • Share equally • Divided into • Share remainder Multiple of Times Once Four times . . . As big Repeated addition Row One each Equal groups of Double Product

  2. Year 3 Addition Phrase which mean you need to add 95 add 10 Add 60 to 14 70 plus 50 What is the total of 26 and 9? What is the sum of 23 and 8? How many are 11 and 35 altogether? Which two or three number could have a total of 23? What must I add to 4 to make 23?

  3. Do you use this method to add numbers together?(Carry method) 47 28+ 35 28 12+

  4. In year 3 we use a number line to add 38 + 27 = 65 48 38 58 65 • Put big number at start of blank number line (saves time) • Add 20 (or two tens) and write where you get to • Add 7 single ones (or jump of 7) and write where you get to • When we split the tens and ones like this, we say we have partitioned the number

  5. Have a go with the number line method Sat Question 1) 42 + 16 = Sat Question 5) What is 25 more than 65?

  6. After your child has used and understood the number line method. He/she will be taught to use this method: 65 25 + 10 (ones) 80 (tens) 90 (total) 65 25 + 80 (tens) 10 (ones) 90 (total) or This is the start of setting numbers out one above the other. Have a go. 38 28 +

  7. Sat Question 7)test the children on their understanding of adding on the number line

  8. Sat Question 7)test the children on their understanding of adding on the number line We might also use a 1-100 counting square to help the children add. • Find the larger number on the square • Each jump down the square adds 10 • Each jump across the square adds 1 65 + 27 =

  9. Year 3 Subtractionphrase which mean you need to subtract15 take away 863 subtract 40subtract 40 from 95what must I take from 14 to leave 6what is the difference between 22 and 5?How many more than 4 is 49?How many less than 28 is 12?How many less than 28 is 12?20 taken from a number is 35. What is the number?8 add to a number is 48. What is the number?Find pairs of numbers with a difference of 30

  10. Is this how you subtract? 46 24 -

  11. +9 +6 +10 +10 30 40 20 14 49 In year 3 we do subtraction on a number lineHow many more than 14 is 49? • Put the smaller number at the start of the blank number line • Put the bigger number at the end of the number line • From the smaller number jump up to the next multiply of 10 • Jump up in as few as possible till you get the bigger number • Add up the jumps to find the answer 14+35= 49 35+14= 49 49-35=14 49=14=35 All these numbers sentences can be worked out from this number line 10+10+9+6 = 35 So 49 is 35 more than 14

  12. Try solving these using the number line Sat Question 6 Calculate 47 – 25 How many less than 28 is 12

  13. When your child is using the number line well, he/she will be taught to set the numbers out one above the other. Vertical method 65 – 28 = 65 28- (to 30) (the next multiple of 10) (to 60) (to 65) total

  14. Sat Question 14) 70 – 42 = ___________ Try using the vertical method to find the answer

  15. Year 3 Division There are 12 star stickers They are needed to be shared out between 3 children How many stickers would each child get?

  16. Year 3 Division There are 12 star shaped sweets They need to be put into bags of three How many bags are needed?

  17. Using arrays to help children understand Multiplication
