This is part of a series of lessons on Scratch - see: All Projects
In this project, students use the mouse to move a target across the screen to shoot ghosts. The coding makes it easy to add any number of ghosts, varying their size and speed,
There are so many really great sites offering Scratch Project ideas. However, many tend to be like recipes - follow the instructions and you'll create a cake. The problem I find is that the students almost mechanically enter code and create "delicious cakes", but without learning an awful lot about Scratch.
My goal is to get students to create a fun project, whilst at the same time learn how the instructions work and fit together. To this end, I use the following approach:
- break the project down into manageable chunks
- present students with an algorithm for each chunk
- provide students with the instructions for each algorithm, but jumbled up
In this way, students learn about algorithms (a VERY important part of coding), and have to understand the instructions in order to sequence them to correctly match the algorithm.
The lessons comprise:
- a PowerPoint with introductory slides, together with the project instructions
- a Word document with the PowerPoint instruction slides printed 2 to a page as a handout for students to follow
- accompanying fully-working Scratch project files for teachers that match each chunk of the project
Let me know if you have any questions or suggestions, and a BIG BIG thanks for looking (as a full time practicing teacher, I KNOW how time consuming this process can be).
ALL my postings are FULLY "classroom-tested" - before I publish, my lessons are tested by both myself and colleagues, rigorously evaluated and discussed, and continually updated to maximise their effectiveness.
But there is always the possibility of error and room for improvement, so do please provide constructive feedback.
REMEMBER... you can earn TpT credits if you leave comments, and I can increase my credibility and reputation. WIN-WIN!
