I need some advice about using manipulatives in the classroom. I am required to use fraction tiles to teach fraction division next week and I am freaking out!! I have no idea how to handle this with my difficult class! I was talking about this to the English teacher on Friday (who also switched from groups to rows because of the same group) and he wasn't sure either. The math coach is modeling the lesson for me with my higher class of 26 students. I wish she could come in to my larger morning classes but she is unable to. I am really grateful that I get to see the lesson modeled once so I can teach it to my morning classes the next day. I am just concerned because every single person needs a set of fraction tiles. That's a lot of materials and I know they will end up falling on the floor, causing chaos. I also remember that the last time I gave markers to the kids, a few kids threw them around the room. The class has gotten better managed since then, however, they are still not as well behaved as my other classes. My mentor said that sometimes the classes like my tough one actually end up doing a great job with fraction tiles. My questions are: -How do I pass out the fraction tiles to all of the students? Should I call one person up to distribute them to the row? -How do I handle kids throwing things? My plan might just be to observe/watch and give the kids a fraction tiles printout if they throw things (where they have to draw it out by hand.) That's what my mentor suggested too. The problem is that if I'm working with kids, they might throw the ties without me seeing. -My mentor suggested that I also teach the "hands off" procedure so their hands need to be off their tiles when I say "hands off." I was talking to the science teacher who has most of the kids in this class at the end of the day. She has been giving detentions to almost the same offenders that I have for talking during class. I gave one girl a final warning at the end of class Friday and said that her only two options right now are detention and a phone call home or doing better on Tuesday. The behavior isn't terrible but it's unacceptable that I have to stop more than twice a class because the same girl is talking. I think this "scared" her enough and most of the other kids are at least doing better behaviorally in that class. I'm a little frustrated because I feel like I am constantly "yelling" at this class. I obviously don't yell, but it's constantly saying "We aren't meeting my expectation, we will try that again" over and over again. The english teacher told me that it is similar in his class. We switch groups so my first group is really well behaved for me and not for him. His first group (my tough class) is better for him (but still not great) and tough for me. Everyone tells me that the second class of the day is always the worst behaviorally.
