The document outlines a lesson plan on perimeter and area that involves students working in groups to solve questions related to finding the perimeter and area of different spaces at a party by using information provided in envelopes. The envelopes give the area and perimeter of objects like gift tables, ice cream bars, clown spaces, and sound systems and students must work together to answer the questions correctly. The learning objectives are for students to understand and identify perimeter, find perimeter of enclosed regions, and solve perimeter and area problems.
