Multidigit Addition

Okay, so we learned different ways, or the names of ways, to answer multidigit addition problems.
-Direct Model is direct model. Haha
-10's is adding by tens. So like for 29+62, it would be 10, 20, 30... 90 + 1 = 91
-1's is adding by ones. So that would be adding through tally marks for example.
-Compensating is like rounding. So for today's problem (29+62) would be like 30+62=92-1=91.
-Incremental was a bit tough for my to understand, but after today I think I have it... Using today's problem (29+62) 62,63,64,65,66,67,68,69,70,80,90,91 orrrrr 29,30,40,50,60,70,80,90,91. Seeing the kids on the video helped. I don't think I'm explaining it well, but its where you break down the number and kinda use a number line.

Manipulative performance assessment is Wednesday... Don't forget!
