Regrouping with Addition

We have been working hard in second grade on regrouping with addition, and I am so proud of my kidlets for expanding their thinking and trying new things! We were always planning to teach regrouping, but partway through the unit, we attended a professional development session on Singapore Math and I was SO inspired, I rewrote my lessons for the next few days to include some of the ideas we saw in the session. There is so much to the program, and I know without extensive training I will never be able to do the principles justice, but there were a few things that I know I can incorporate into any math program I am teaching.
