The fourth graders finally finished their visual proofs for multiplication. As I hung the first one out in the hallway, a student said, “Ahhh, the feeling of success!” I know this activity was a little frustrating for some, but that really is OK. If you’re coming for Back to School Night, please stop by to check out their work. The best part is that some of the criticism that stung a little yesterday seemed to be a little easier to deal with and to make changes. Everyone grew a little as they worked on this activity.
Second grade math learned a little more about algebra today as they had to solve equations that only had numbers on one side. Their equations had sea animals on one side and a number on the other side. For instance, a sea horse + crab =9, a sea horse + a sea horse = 8. Students had to determine what the sea horse and the crab were worth. They also have to explain their answer, which has proved to be the trickiest part of the assignment. An important lesson we’re working on involves knowing when to ask for help. There is a happy medium between asking too soon and waiting too long. As second graders, they will become better at this skill as the year progresses. I introduce the assignment, then sit at the “fire pit” (the kidney-shaped table) and wait for them to come to me. It’s all part of the dungeon theme about which they like to complain.
We’ve been reading an Eyewitness WWII book to go along with The War That Saved My Life. We had our first great discussion today. Students had great questions about the war itself, as well as the connections to the novel. We did get off on a few tangents that maybe weren’t in the book but were relevant to the discussion. Book discussions with fourth graders are by far my favorite thing to do. They’ve really started to think about the world around them and their place in it and I never know quite where a discussion will go once we’ve started.
Third grade math continued to try to determine the area of a polygon using a geoboard. One group graduated to a piece of paper, but the other groups are close behind. They were allowed to start with rectangles but can no longer do so, which means they now need to decide how to measure using fractions of squares. There is a lot of math tied up in what they’re being asked to do. This will give them a solid understanding of area, as well as the difference between area and perimeter. Last, but not least, it will also help them understand the concept of area as multiplication, further cementing their understanding.
I hope to see you at Back to School Night this evening!
