I use this PowerPoint throughout my unit on perimeter as whole group review and practice. I also print handouts for students to complete independently and then we check our answers together on the board. It starts with very basic perimeter (counting units) and progresses to using perimeter formulas and then into perimeter with missing side length and perimeter word problems. Includes tons of perimeter practice problems to use for whole group instruction or independent work!
Tip: The different colored shapes signify separate days on which the material is presented. For example, the slides with blue shapes are for day one of the unit, green shapes are for day two, pink shapes day three, yellow day four, red shapes day five, etc.
