Lesson 6

Rosie's Runtime

In this unplugged lesson, students will construct algorithms to guide Rosie the Robotic Dog on a game board. In the game, students help Rosie to fetch her bones and navigate to her doghouse, while avoiding mud puddles. Students will learn that computers do only exactly what you tell them.

Agenda

Video: What Is An Algorithm
Play Rosie's Runtime
Brain Break: Doggie High Five
Reflection & Close-Out:
- What was one challenge you had when writing an algorithm for Rosie?
- How did you work together with others to write an algorithm for Rosie?
- Did you fix any bugs in your program? How did you fix them?

Materials

2 sets of Rosie's Runtime materials:
- floor tiles: start, end, 4 mud puddles
- 2 plastic bones
- Twister mats
2 sets of Rosie's Runtime Command Cards: small / large
