My announced observation is on Tuesday and I am trying to get a lesson ready for it today. My mentor who teaches the same subject and grade as me helped me come up with a plan for the lesson. I've gotten pretty good evaluations so far from my principal but I know he likes to see a lot of group work, etc. My objective would be "SWBAT solve ratio problems using a table, double number line, and proportion." My plain is as follows: -Do Now: completing a ratio table + sharing strategies (10 mins) -I would then give students a ratio task to work on and I would assign each group a strategy (table, double number line, or proportion) . They would have some time independently (maybe 5 minutes) and then finish solving the problem with their group. I would then give each group chart paper to show their solution on a poster. (30 minutes) -Students would then do a gallery walk where they record the strategies of other groups and identify two similarities and two differences between each strategy. (I'm confused about how to run a gallery walk though...the kids would only need to switch to 2 groups. I could have all of the tables stick their chart paper in one part of the room and have 9 kids moving together maybe?) (10 minutes) -We would have a class discussion about similarities and differences. If time, I would plan an extension problem, but I don't think there would be. -Exit Ticket where they solve a problem with at least 2 strategies (5 minutes) I'm concerned because this is very "student lead" but it is also my best and highest class...so I think they would be able to do it. Behavior hasn't been perfect with this group but I know it won't be a problem with the principal in the room. I'm just hoping that the gallery walk goes alright! I was thinking that I could have the kids leave their chart paper on their desks and just have the kids move desks so they're not all around the room? I'm not sure.
