Type: Lesson/Unit Plan

Overview:

The class works in groups to design aluminum foil boats that will support as many pennies as possible. At the end of the lesson, groups reflect on their experiences with the activity and make connections to the types of problem-solving they will be doing for the rest of the course.

Grade: 6
5) Identify algorithms that make use of sequencing, selection or iteration.

Examples: Sequencing is doing steps in order (put on socks, put on shoes, tie laces); selection uses a Boolean condition to determine which of two parts of an algorithm are used (hair is dirty? True, wash hair; false, do not); iteration is the repetition of part of an algorithm until a condition is met (if you're happy and you know it clap your hands, when you're no longer happy you stop clapping).
