Second Grade Math Warm-Ups: 8-18 to 8-21

When I first started using math warm-ups a couple of years ago, I had no idea how useful they would end up being in my classroom.  They are quick, easy and definitely give me a bank for the buck.  So of course I am using them again now that my mathematicians are second graders!  Here is how we got started this year:

Wednesday

I waited until the second day of second grade to start, and since we spent all last year doing this, most of my friends knew exactly what to do.  I just had to introduce my new friends (there are 4 of them) to this routine.  I started with a question everyone could answer (and if I remember correctly, it’s one of the first problems we did last year, too).

As I think about how we’re getting started in Math this year, our focus will be on making sure we have a firm foundation of basic skills and facts before we move on to other things.  That means we’re going to review combinations that make 10, doubles, doubles +/- 1 and basic addition/subtraction facts.  Hence the next question:
