math, Number Sense & Numeration, Number Strings

Back in the groove

On Wednesday of this past week I realized I had gotten back into the groove of teaching math. I had been in it but fell out at some point. I knew I was not enjoying math and that I was feeling every day like I had missed the mark – the lesson was too easy, or it was too hard, or there were some interruptions that derailed us too easily. At some point I realized that there were so many different math strategies being used in the class that it was hard to have a conversation about our math. I decided that this week we would talk about all the strategies but we’d focus on making sure everyone could use a number line. We finished the Fosnot “Measuring for the Art Show” unit in about 3 days (should take more than that, and has typically taken me 10 days.) I decided to spend some time doing number strings and reinforcing the use of the number line to do it.

Here you can see we are using a lot of different strategies. Someone even suggested the traditional algorithm and several students knew how to use it. I’m crediting “at home learning” for that because this hasn’t happened in many years for me!

After two days of this, I asked everyone to complete three problems that I put on the board. They each have a whiteboard they were using to do this. “Do these three problems, and then you I want to take a photo of you and your work. Then you can clean up for lunch.” I thought that was good! But several of them were annoyed at ONLY being given 3 problems. I had to add more to the board. So, to recap, they wanted to do more math instead of get lunch.

I finally said, “Look, if you want to do this all day you could make up problems for each both er.” Then they spent the rest of the day making up problems for each other. A few of my friends weren’t sure what to do. I cancelled reading groups for two days to do math groups instead. By the end of that they knew how to add double digit numbers with the Base-10 Blocks and with the number line. We’ll get to the mental math eventually, but I needed to give them a few strategies to hang on to until then.

This week we’ll move on to another Fosnot unit called “Ages and Timelines” which has us focused more on subtraction, or rather “finding the difference” between two numbers. I feel like it will be a good fit for us.

I’m not sure if completing all of my math interviews would have helped. I still have a few to go (lots to go!) but what I already know about the class is that we are coming to the math from a variety of places. One of my small groups clearly knew what they were doing even though they had struggled with the first lesson and had given themselves a 😦 when I asked everyone to self assess. I asked them to explain.

Them: Well, I didn’t know this is what you meant.

Me: You don’t know I wanted you to add the numbers?

Them: No.

So, to recap, after two days of me saying “Add these numbers up.” They didn’t know what I meant. Like I said, we’re coming at this from a lit of different places. But I think we’ll mostly be in the same place, together, by the end of next week.
