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!

Thinking ... Thinking ...
So, I can see why fractions are hard to teach to students. Its so hard for me to think of other ways to teach it without teaching the rules. I keep reverting to them in class when we go over it.
Last class, I started understanding what the fractions consisted of. I hope that by the end of class today, I should have a better handle on it.
I'm having a bit of a tough time explaining conceptually in words, still. It is much easier for me to talk about it.
So, my question is how does a teacher go about teaching fractions to the kids who are ready without being confusing?

I R Slacker ... and Sick
So, I haven't posted in a week. Sorry sorry, I've been sick with a pretty bad cold, and it's totally kicking my butt.
Over the class break, we were given a problem to ponder: What is 2/3 divided by 1/4?
Okay, so in order for me to even think about this problem, I had to solve it first. It has been a while since I've done fractions, but I figured it out.
Another way I would have figured out this problem would have been to draw it out on paper. You would see that 1/4 goes into 2/3 evenly twice, but there is a small part that 1/4 can not fit into. However, it is close. You would have 2/3 of that 1/4.
I'm having a tough time conceptually explaining this answer. (That's probably the cold meds.) I' ll try angin .
