Mental multiplication strategies – split strategyThe split strategy is when we multiply numbers in 2 pairs and then add the parts.Let’s use the split strategy for 26 4. Split 26 into 20 and 6. Multiply each part. Add the answers together.26 4 20 4 6 480 24 104So, 26 4 1041Use the split strategy to answer these:a34 3 30 90 3 4 3 So, 34 3 b45 5 So, 45 5 c52 4 So, 52 4 Multiplication and DivisionCopyright 3P LearningE3SERIESTOPIC17

Mental multiplication strategies – compensationUse the compensation strategy to make it easier to multiply 2-digit numbersthat are close to a ten.Look at 4 19.19 is close to 20, so we can multiply by the next multiple of ten which is 20.Then we build down because we have an extra group of 4.4 19 4 20 80 – 4So, 19 4 761Use the compensation strategy to answer these:a 5 29 5 So, 5 29b 3 49 3 So, 3 49c 4 39 4 So, 4 392– – – Use the compensation strategy to answer these questions.This time you need to look for more than one extra groupto subtract:a 4 18 4 –So, 4 18 b 3 17 3 18 –So, 3 17 E3SERIESTOPICMultiplication and DivisionCopyright 3P LearningWe have rounded upto 20. So instead of4 18 we have 4 20.This is 2 more groupsof 4. So we subtract 8.

Mental multiplication strategies – choose a strategy1Roll a die to get the missing number, then use either the split orcompensation strategy to get the answer. You can place the numbersrolled on the die in any question.a 25 So, 25 b 36 So, 36 c 49 So, 49 d 58 So, 58 Multiplication and DivisionCopyright 3P LearningE3SERIESTOPIC19

Mental multiplication strategies – doubling and halvingWe can change the factors of a multiplication question to make it easier. Lookat 16 3. If we halve the largest factor and double the smaller factor, we makean array on the grid that is the same size. Both arrays have the same amount ofsquares. Count the squares, are they equal to 8 6?16 Halve813Double 6 Make these problems easier by using doubling and halving.

Division – division is sharing and groupingDivision can mean sharing or grouping.There are 12 lollies shared between 4 kids. How many are in each share?12 4 3There are 16 apples and 4 go into each basket. How many baskets do I need?16 4 41Solve these sharing and grouping questions:a There are 9 cupcakes and 3 kids are sharing.

Division – division is sharing and grouping2Draw pictures to show thesedivision questions. Then write thedivision fact and decide whether itis a sharing or a grouping question.If you need to find outhow many items thereare in each share, it’sa sharing question. Ifyou need to find out thenumber of equal shares,it’s a grouping question.a Divide 16 lollies between 4 girls. How many does each girl get? sharing / groupingb From a packet of 24 pencils, each person will get 6. How many people aresharing the pencils? sharing / groupingc 48 eggs are laid by 6 hens.

Division – division is repeated subtractionDivision can also be thought of as repeated subtraction.Look at 30 5 ? This question is asking how many groups of 5 there are in 30.Jump in 5s along the number line and then count the jumps.6 55 5014 55103 52 515So, 30 5 61 5202530Show these division facts as repeated subtraction.
