Lesson Details
Key learning points
- Programs can be created based on designs.
- A project can contain multiple sprites each with separate sequences of code blocks.
- An algorithm is a defined sequence that can be followed and represented in code.
Common misconception
Once the project has been programmed, it's finished.
It's important to test and debug to make sure the project works as intended. Look back at what was set as to what would make the project a success and consider how well the pogram carries out the task.
