I could sure use some help planning this demo lesson - the lesson is tomorrow and all I know is that the students are incoming eighth graders who are academically at-risk and that my topic is data analysis and probability. I don't know how long the lesson is supposed to be, how many students there are, or what they've been doing..so I want to keep it simple. I'm thinking of a lesson involving M&M's (well, probably not actually M&M's since I don't want to worry about allergies, I just think of it as the M&M activity) where we calculate the probability of pulling a certain color and then make graphs. Any tips on how best to make this work? Ideally I would have the students, in groups, do the work of counting how many pieces of each color, and the total, but maybe we should do it as a class since I don't know how many students there will be? Also, should we make the graph as a class or should I try to bring graph paper? I would love to do the graph in color, what if they don't have markers/colored pencils? What about rulers? I'm also taking suggestions for what to use in place of M&M's...I need something I have around the house; I was thinking Legos. I just found out the topic and grade level Friday after hours so I did not have an opportunity to contact the district for more information, so I'm at a stand still. I want to come in prepared, but I don't have time to do a lot of gathering materials! I am taking ANY AND ALL tips or suggestions that you can give. Please help!
