Depending on your classroom, you might want to either have them fix each mistake one at a time (with demos in between) or students might feel comfortable working together to fix the entire program. Pair: Have students work on solutions to get the bird around the TNT. Think: How can I fix this program so that I don't run into the TNT? Should I throw all of the code away and start over? What am I feeling right now, do you think? It won't be long before you run into a block of TNT. As the teacher, let them know that you are SO SMART that you already put all of the code in that you are going to need to solve this puzzle, then ask them to watch you "Run" it by moving your finger (or a penny, or some other indicator) along the path. Model: Tell students that you have this workspace on display that looks just like the area that they will see when they start to do the puzzles online. Make sure that you have pre-placed the movement blocks in the workspace using Unplugged Maze Blocks - Manipulatives in a configuration like the one below: This short activity will help students relate the ideas of persistence and debugging to the puzzles that they are about to complete online.ĭisplay: Project a copy of the Course C, Lesson 2 Maze Bridging Page - Puzzle Manipulative (PDF) for the class to see.
