These outlines show the questions, examples, checkpoints, and projects used in class. They describe the teaching; current scheduling is discussed directly.
Scratch & Game Design
Scratch & Game Design / Events and Commands
The robot hamster has five perfectly good commands and no idea when to begin. Give it a trigger, arrange the commands, and see how one change in order alters the route.
Read the lessonScratch & Game Design / Coordinates and Movement
A giant pigeon is chasing your character across Calgary. Give both sprites reliable positions, move the player with x and y, and decide exactly what counts as being caught.
Read the lessonScratch & Game Design / Loops and Repetition
One snowball is an inconvenience. Fifty copied snowball scripts are a maintenance problem. Put the attack in a loop, control its timing, and give it a reason to stop.
Read the lessonScratch & Game Design / Conditions and Decisions
The Quiz of Questionable Knowledge has received the answer 'moon cheese.' Its code must decide whether that is correct, give useful feedback, and move on without awarding seventeen points.
Read the lessonScratch & Game Design / Variables and State
The space pet insists it was fed, but the program has forgotten. Give its needs names, decide what changes them, and make every new game start with a clean memory.
Read the lessonScratch & Game Design / Sensing and Collision
The floor is convincingly lava-coloured. The computer remains unmoved. Define what counts as danger, check it while the player moves, and make one collision cause one result.
Read the lessonScratch & Game Design / Debugging
The game fails only when the player reaches safety while being caught near the right edge. Random edits have made it stranger. Reproduce the fault, inspect the game state, and test one possible cause.

Robotics / Input and Output
A delivery robot has been told to 'go around the chair.' That instruction works on people and fails on robots. Replace it with measured moves and turns that can be checked on a grid.
Read the lessonRobotics / Sensors
The display says 347. That might mean bright, close, tilted, or nothing useful at all. Find out what the sensor measures, collect readings, and decide where the program should change its response.
Read the lessonRobotics / Feedback
The patrol route works until somebody moves a box into it. Add a distance check, choose a recovery action, and make the robot test the route again instead of turning forever.
Read the lessonEvery lesson ends with evidence.
A student runs the project, explains a rule, identifies a change, and shows what happened after a test.
