Today is a bit of sneaky practise. We are adding equal groups. So its repeat addition (multiplication in a different way)
So, each group is worth the same. 4 groups of 6 is 6+6+6+6 and the answer is 24.
That is the same as doing 4 x 6, but as we haven't practised our 6 times tables, we can still find the answer by adding together the equal groups.
So. What is the answer to 4 groups of 3?
What about 3 groups of 6?
How about 4 groups of 4?
7 groups of 7?
You can definitely use your counters and objects to help with your addition. If you also want to write down each step so you keep track I think that is a good idea.
So, if I was doing the 4 groups of 6 question, I could count on 6 more from 6, getting to 12. I write that down, and then start again by counting on another 6, I get to 18, which I write down. Then I count on another 6 and I get to 24.
