Peanut Butter and Jelly Algorithm / Sequencing Activity
Teach ALGORITHMS AND SEQUENCING. Students will "code" a set of instructions, the algorithm, to help a robot, yourself, make peanut butter and jelly sandwiches. Students will create their own algorithm for the robot to use and make a sandwich. They have two tries! Usually the first try is going to messy and fun as the teacher/robot tries to follow the steps. Once they learn from their mistakes (debugging) they can try again, usually with better results. SLIDES 1 - 5 ARE TEACHER INSTRUCTIONSSLIDES
