Yesterday I posted last week’s (or at least the LAST week that we were in school’s) math warm-ups.  I mentioned that there’d be more about the strategies on which we’ve been focusing.  Well, that time is now.  Hope this makes sense and gives some insight into the work we’ve been doing for the last few months.  Well all quarter, really…but I digress.  Here we go. 🙂

One thing I wanted to do was to be able to SHOW how these strategies work, and even better, have KIDDOS involved in that work.  So, just before we left for our break, many of them volunteered to help me with a project.   I have a Tweep (that’s a friend you know from Twitter, for those who might not know) named Shannon in Alabama who was interested, too, so this is for you and your friends, lady! 🙂

Ok…so here are some videos of our Rm. 202 kiddos explaining more about how to add 2-digit numbers using place value strategies!  (I will mention, though, that they are a little rough, so ignore the bumpy parts and see the big ideas, ok? THANK YOU!! 🙂 )

Sticks and Dots

Splitting 10s/1s

Keeping 1 Number Whole

(This one’s a little long, and shows more than 1 strategy, so be prepared for that!)

Compensation

Hope this helps–and WAY TO GO, RM. 202 KIDDOS!!  You are ROCKING mathematicians!! 🙂
