The group with the most points at the end of the class period wins!||Lesson Objectives:||Review Programming Skills.|
A first exposure to making risk/reward decisions.
|Materials Needed:||One NXT kit per group|
Computers with Mindstorms NXT software
Black electrical tape
|Preparation and Set Up:||Put together a list of challenges on a worksheet. They should range in difficulty level from very, very simple to challenges that are more or less impossible to complete. Assign point values to the activities based on their difficulty, keeping in mind that close scores are more fun and drive the students to keep working. An example worksheet is attached below.||Necessary Background||This activity is as much of an activity in assessing risk/reward and strategy as it is in programming. Some students will complete many tasks with simple, fundamental programming. Others will bite off more than they can chew, and end up without many points at all.||Procedure|
- Introduce challenge day and go over what each challenge calls for specifically.
- Hand out worksheets and set a strict time limit.
- Update scores on an overhead or white board.
- After the time is up, talk with children about risk/reward, and about how hard each challenge was. If they could do it over again, which would they choose? which were fastest.
