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).

Friday

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:

Note that I had to revise my question, since kiddos wrote 1 combination and thought they were finished.  I drew the visual of the 10s “rainbow” as we discussed the problem, and it was good to hear a couple of friends say, “Oh, now I get it!”  Like me (who is a visual learner), seeing how those numbers connect is important to their understanding.  This is definitely become an anchor chart in our classroom!

1. Great way to start the day getting the students thinking.
