# Math Warm-Ups January 28-February 1, 2013

Another busy week in Rm. 202!  This week we only had three warm-ups because of our schedule.  Enjoy solving them!

Monday

This warm-up was a nod to the next part of our geometry unit–coordinate grids.  We’re also going to continue to practice “old” skills like adding fractions to keep them fresh–and because many kiddos still didn’t quite get it during our fraction unit.

Tuesday

One thing that I want to make sure I always highlight for my kiddos is the fact that they know many things that help make math easier in their heads than on paper.  I want them to be flexible thinkers, and know how to do things in more than one way.  This one was a way to get them thinking about using  known (in this case a multiple of 10) to help them figure out a problem.  Below it is the number string that we worked through after the initial conversation.

Wednesday

Can you tell we ran out of chart paper this day?  Nothing like using every last bit of it!  While this question could have been seen as “easy” to some, I was hoping that since we’d done these before, kiddos could dig deeper and share a problem that was harder than just this plus this equals 125.  I LOVED it when Luke through out a problem with exponents!  We had a great conversation about how they work, and the best part is that we’re going to do more with them during our upcoming decimal unit–as we discuss expanded form.  It’s so great when kid provides a natural connection without even knowing it!  You can’t plan that kind of stuff.  Beautiful. 🙂
