Where To Start Teaching Multiplication

Multiplication is considered one of the first complex concept the child will learn in primary one. In typical school environment and textbooks, it usually starts by 2 times table followed by 3,4,5,6,7,8,9 etc.

Question here is, does our brain learn better in this sequence?

Fact of matter is, we should approach from what the child is familiar with.

In this case, 10 times table is probably a good start. Why? They have been learning to count by groups of ten haven't they:)

Once 10 is done, 5 can be taught easily as they just have to 'insert' a five between every 10 times table.

Next on the list is 2 times table as it is based on the even numbers pattern and also just a modification of sequence counting but adding one more.

4 times table can follow on from 2 as it is just even numbers but with skipping one even number.

8 times table requires what I call visualization. Basically you have to realize that 8 times table is just a matter of adding 8's. And 8 is just 10 short of 2. So we can actually just add 10 every time and minus 2 e.g. 8 -->18-2--> 16--> 26-2-->24 etc

I have used this on student using special worksheet and did a test. The student actually took half the time in his times table calculation!!

There rest of the tables requires some other manipulative which I will explain in future.
