Students select a job that they want to do in the future, then determine the type and amount of space they will need for their job. Students identify the area and perimeter of the initial space they are designing, then find the area and perimeter of at least 3 additional things within this space (e.g., for a playground, I find the area and perimeter of the swing set space, the field, a slide, a seesaw etc.). Students complete a graphic organizer to ensure that their smaller pieces can fit inside their larger space, then represent their tasks on a choice of medium (Scratch, 3D representation, clay, drawings, poster, Google Slides). Students then present their task and explain why area and perimeter is important to know how to use.
