MULTIPLICATION and DIVISION: deriving multiplication facts This is what I can do and what I can’t do yet.   Lukas   Term 4 2016
Doubling	8 x 3 → 2x (4 x 3) I don’t know the answer to 8 x 3 = but I know the answer to 4 x 3 = so I work out 2 lots of 4 x 3	Use doubling to solve this problem. 6 x 4 =
Adding and Subtracting from a known problem	8 x 3 → (7 x 3) + 3 I don’t know the answer to 8 x 3 = but I know the answer to 7 x3 = 21 so I will just add one more 3 to 21	Solve this problem by using adding or subtracting from a known problem. 11 x 4 =
Reversing	63 ÷ 9 → 9 x ? = 63	Solve this problem by using reversing. 48 divided by 8 = 8 x ______ = 48
Doubling one number and halving the other	3 x 12 → 6 x 6	Solve this problem by using doubling and halving. 12 x  5 =
Multiplying by tens and hundreds	70 x 5 → 7 x 5 x 10 I don’t know the answer to 70 x 5 = but I can work it out by doing 7 x 5 = 35 and then 35 x 10 = 350	Solve this problem by using tens 60 x 4 =
My reflective comment/goal setting: This page just shows the kind of problem you can solve as you worked the answers out on paper.I kind of get the feeling that you weren’t paying enough attention to the instructions and examples as most of these problems are easy.  You need to go back and re-do some lessons in  Maths Buddy which teach how to use these strategies. You could also look for and view some lessons on Youtube. Try using the pink highlighted words as search terms for solving multiplication problems. Mrs B😉
