(Debugging)
Learning Intention
● I can test and debug my programs
● I can test and debug my programs
Introduction
Start with the script below. Alter the script for yes to include a space (or if you want to be make it easier a full stop after yes. Ask children to predict what the code will do when it runs and you enter yes or no.

Ask children to observe what Ohbot does closely when the code runs. Run the script. What does Ohbot actually do?
How is it different to what we want?
Model going through the code line by line. Ask children to explain line by line in pairs describing what each block
does.
Get children to work in pairs to come up with possible solutions to make Ohbot respond to the answer.
Run children’s code suggestions.
Explain that they can adopt this approach to debugging their own code.

Activity
Children open up Ohbot projects they have written this term. Which work and which could be improved? Can they
debug their programs to fix them?
Extension
Can children add extra code to their programs to improve them?
Plenary
Evaluation of the Ohbot project. Children to complete the following feedback.
