Times Table Tricks
These are tricks and skills to help students master learning their times tables. Teachers can use these when learning certain groups of times tables as a class. These tricks will make teaching the harder times tables easier.
When multiplying by 1, the number of the other multiple is the answer. For example, 1×5=5. 1×9=9.
When you multiply a number by two, you just double that number.
When multiplying by 3, add the number three times. That is 6 x 3 = 6 + 6 + 6 = 18. This might take a bit too long, although with practice, you start memorising the answers.
If you know how to double a number, this one is easy. Simply, double a number and then double it again.
The last digit is always going to be 5,0,5,0 or you can use this method. Take the number you are multiplying by 5 and multiply it by 10. Then, if you halve your number, you will have your answer. For example: 9×5 =45 so 9×10 = 90 and 90/2 = 45.
When you multiply 6 by an even number, they both end in the same digit. Example: 6×2=12, 6×4=24, 6×6=36. Or you can use the double method. If you know your three times tables, simply double the answer and it will give you your six times tables.
Firstly, the hardest multiplication is 7 x 8 – I like to remember this as 5 6 7 8 – 56 is 7 x 8. Otherwise, the 7 times table can be derived from the 4 times table plus the 3 times table. For example: 7 x 8 is the same as 4 x 8 = 32 added to 3 x 8 = 24, giving an answer of 56.
Here is a simple step to help solve your eights. Take any number and double it. Then double the answer again. Now double the answer again. For example 4 x 4 =16, so double 4 = 8, then double 8 = 16.
Hold your hands in front of you with your fingers spread out. For 9 x 3, bend your third finger down. (9 x 4 would be the fourth finger, etc.) You have 2 fingers in front of the bent finger and 7 after the bent finger. Thus, the answer must be 27. This technique works for the 9 times tables up to 10.
If you want to multiply something by 10, just add a zero on to the number you are multiplying. For example: 10 x 8 = 80 or 10 x 11 = 110. Try it with any number; it’s just too easy.
Take any number to 10 and multiply it by 11. Multiply 11 by 3 to get 33, multiply 11 by 4 to get 44. Each number to 10 is duplicated.
The twelves can be multiplied a number of different ways. Here is a simple way to learn. Multiply by 10 and multiply by 2, and then add the two results to get your answer. For example: 12 x 3 can be calculated by working out 10 x 3, which is 30 and adding 2 x 3, which is 6. This gives 36.12 x 4 can be calculated by working out 10 x 4, which is 40 and adding 2 x 4, which is 8. This gives 48.
