It has been touch and go and I've been trying to make it as interactive as possible. My students are always up for anything that I present to them and today was just the same. I went into today's lesson thinking that I was going to start subtraction (without regrouping), but once I wrote the header on the board, I came to me that I needed to do more addition, but with regrouping this time.
We warmed up with a card game (similar to "war") where students work in pairs with a deck of cards and they each flip a card over and add the faces together. Whomever adds up the faces correctly first gets the cards. It has been a major hit with my students (because they are uber competitive and sponges for learning), so I figured it would be a good lead in to the addition with regrouping.
I reconvened everyone and presented a problem where they had to regroup. We discussed the need to remember the place value columns and what the digits in a two-digit number meant. We spent a few minutes composing and decomposing numbers to get the idea of what numbers were really made of.
We were then off to the races to try and add with regrouping. In trying to keep it simple, I stuck with a simple algorithm that they could follow the steps/pattern to. With everyone engaged and wanting to share what they thought was the "right way", I turned the floor over to them and asked for a turn & talk. They needed to talk to the person beside them how they were going to solve 38+96. This is where I went scrambling for my ipad to record a conversation between two students (grade 2s) about what they immediately saw about the numbers and the steps that they were going to take to solve the problem.
This left me so proud of where they have some from since September when they wouldn't even talk about what they saw or what they wondered. It was an unintentional moment, yet perfect. I was ecstatic that could capture it on video. Next time I would stop questioning them and hope that they would continue to talk about what they saw and hopefully get up and demonstrate their ideas on the board to solidify their understanding.
Until tomorrow, I hope that there's sunshine & happiness in your day similar to what I had today with my math talks.
