Our team has found that splitting up work into sections helps with efficiency and time management. It also allows team members to focus on a few subjects, instead of doing everything. In FLL specifically, you want to make sure that everyone gets to be in a team that is part of Project, and a team that is part of Robot Game. In Project and Robot Game, you want to figure out the different sections (Programming/ Building/etc., Problem/Solution/etc.), and place team members into those sections based on their strengths. However, there should also be a time where the whole team works together on things, like when doing Core Values challenges, or having a break in between.
Make sure to talk to experts and help out new teams (if possible)! Go on Field trips to learn more about your project, and to help you formulate your ideas. Then, when you've figured out your project, share it with the people who helped you develop it! Try to share your project and skits with your class, other children, and experts. Make sure you get their feedback, so that you can build on your project.
When you go to a tournament, you'll generally make a tri-fold presentation that is displayed in your pit and is shown to the judges. We always made 3 tri-folds: one for Project, Robot Game, and Core Values. In the tri-folds, you want to make sure to include your thought process, and the different parts of that subject. For example, in Project, you would want to include your problem, solution, experts you met, and many more. You should also include a lot of pictures, and make the tri-fold look organized so that people are drawn to it and it's easier to read. We also had binders which included the information in the tri-fold for people to read, if they preferred that, and judges to keep.
Discover and Share is an amazing method, that allows teammates to get to know each other and learn about something new! Every week, one member of the team presents about a topic of their choice, that relates to FLL. That team member does research on the topic that they choose, and makes a 10 to 15 minute presentation to explain it. This way, everyone learns about it, and team members get more used to presenting!
