# Is this an ok addition strategy?

## Recommended Posts

Ds 5 has just started doing addition over ten and I taught him the making tens strategy. So, I want him to do 9+7= 10+6. He pretty much can add everything really quickly and when I ask him how he gets his answer he will say 9+7... Well, 10+7 is 17 so 9+ 7 is 16. Or 8 plus 6.... 10+6 is 16 so 8+ 6 is 14. He does it really fast, but I'm not sure if this will work out forever. Is this just a variation on the making 10s?

That sounds like a good strategy to me, and it sounds like it makes good sense to him. It sounds like he enjoys working with numbers, and that is great! Keep up the good work!

As a math tutor, I am not hung up on how the kids get to the right answer but the fact that they know how to get to it. He is understanding the concepts so if it is easier for him to think that way, and I think it is, I would let him continue with this. Eventually, he will drop the step he is doing in his head and just remember that 9+7=16.

I'm not an expert (my kids are 8) but I have a child who used his own strategies too. He's what I'd call mathy and it seems to be working well for him so far.

I still taught the strategies our program (RightStart) presents but he uses what's most comfortable/makes sense to him. Like your son his mental math is quick--quicker than mine often.
