Chapter 13 of my Pre-Algebra curriculum covers area, circumference, surface area, lateral area, volume, area of composite figures and negative spaces, surface area and volume of composite figures, and similar solids. There are 12 lessons, 3 quizzes, a chapter review, chapter test, and chapter project where students will design, sketch, and build model playground!
