So this week we have been working on Addition with Regrouping!
Here is a video to show you how to add when you have to regroup. Remember it might be with two digit numbers!!
Let’s show our thinking and add the addition problem 64 + 2
Decompose your number: 64 = 60 + 4
Ones first: 4 + 2 = 6
Tens next: 60 + 0 = 60
Sums finally: 60 + 6 = 66
Below I would like for you to show me your thinking in how to solve the problem 36 + 15
Challenges:
72 + 39
38 + 36
45 + 17
54 + 23
You can use the strategy we did today if you would like.
first i combine the tens then i combine the ones.
ms. zatarga i did the same thing as matthew
I yous tens and ones.
I looked at the tens first and added and then added the ones; I saw the ones had a ten in it, so I regrouped and put that ten with the tens I added earlier
I did the same as Eill and Matthew x?????
