Math Warm-Ups Sept. 17-21, 2012

I think I said it in my last post, but golly–being sick is hard!  Someone around my house has had a cough for at least a month now, and I’ve had one for at least 2 weeks!  Hence my absence from blog-world for that long.  All I could stand to do was fall into my bed and sleep when I got home.  Luckily, though, I’ve been to the doctor and gotten some medicine and am on the mend.  So here I am. 🙂

The horrible thing about not writing for two weeks is that I have a million and one things to post about that have happened, but I’m not really sure how and when I will get them all done–because new things keep getting added everyday!  So I guess I’ll start here and see where it takes me.

Last week we were working on division in math, but then added in some practice (an introduction really) with order of operations.  Here’s what our warm-ups looked like:



I was gone and so don’t have a pic of this one, but they solved the problem that they wrote the story for on Monday, using an efficient strategy.


When we started, the red parentheses were not there, and so many were not sure which part to do first.  This was the introduction to using order of operations.


The original problem is what’s written in pink, and the brown is our work after we talked about how to tackle it.


I love how complicated this one is!  This one tricked many friends, but we’re getting a hang of it now that we’ve done it several days in a row.  This was a brand new concept to most mathematicians in my room.

How did you answer our math warm ups?  What can you tell us about using Order of Operations to solve problems?  Any advice you can give us?  Thanks for leaving your comments to help continue our learning. 🙂
