Memorizing the times tables is a tedious yet extremely necessary skill for any child learning multiplication. By memorizing the single digit times tables, your child can multiply any two numbers without the use of a calculator. However, the process of actually memorizing is often tricky and frustrating for your little learners. That is why it is great to teach them easy tricks to remember the times table. Here we will show you a few tips to teach your kids how to remember the nines times table.
Here is the nine times table through ten:
9 x 1 = 9
9 x 2 = 18
9 x 3 = 27
9 x 4 = 36
9 x 5 = 45
9 x 6 = 54
9 x 7 = 63
9 x 8 = 72
9 x 9 = 81
9 x 10 = 90
There is a simple pattern in multiplying numbers by nine. In the tens column, the digit is the number multiplied by nine minus one. In the ones column, it’s the number that, added to the digit in the tens column, makes nine. This trick makes memorizing multiplying by nine less about multiplication and more about simple addition and subtraction.
Here is a more visual example of this simple trick:
If your child is a visual learner, there is another great trick for remembering the nine times table. Have your child put their hands out palms down, with their ten fingers splayed out. From left to right, count the fingers by how much they are multiplying nine by. When they get to that number’s finger, put the finger down. The fingers before that represent the number in the tens column, and the fingers after represent the number in the ones column.
For example, if your child is attempting to multiply 9 x 5, the finger they should be putting down is their left thumb. To the left of the thumb finger, there are four fingers up, signifying there is a four in the tens column. To the right of the thumb finger, there are five fingers up, signifying there is a five in the ones column. Therefore, the answer is 45!
This goes even further than through the first ten numbers. No matter what you are multiplying by nine, the digits of the answer will always add up to nine!
9 x 38,502 = 346,518; 3 + 4 + 6 + 5 + 1 + 8 = 27; 2 + 7 = 9!
If kids are multiplying larger numbers by nine, this is an easy way for your child to check their work without a calculator.
Taking the jump from addition to multiplication is a big one and can be overwhelming for your little learners. But if you teach your child easy-to-remember tricks that create shortcuts to answers, multiplication will become a little less daunting and a lot more fun for your child.
