Computer Science Unit: Designing Computer Games

Interactive computer games are powerful tools for learning. In the story Lerato’s Playful Program, Lerato designs a computer game to help her neighbors recognize the positive environmental impact of choosing to cook with solar ovens. Students explore the programming language Scratch, and then use it to design a practice computer game. For their final design project, students choose an environmental issue and then follow the steps of the Engineering Design Process to imagine, plan, create, and improve a game that helps players learn about the environmental consequences of their choices. Students extend their computational thinking skills to mathematical concepts as they practice multiplying fractions.
