1. Have students program a simple movement system for scratch. Up, down, left, right using x and y. Maybe go over it with students if they need help. 2. Have students add another sprite. This sprite will be the thing they'll be chasing. 3. Have it so if the character touches the object they're chasing, have it teleport randomly and make it play a sound. Bonus: If students are done early, have them make multiple objects they can chase. They can also make it a two player game as well with alternative controls.
