This is an introduction to area and perimeter that would work for grades 3 or 4 and connect to Common Core State Standards. I tried to make this a very teacher friendly resource with teacher prompts and headings that describe the type of instruction involved.
There are five total lessons that involve the formulas connected to area and perimeter, story problems, guided student practice, students measuring objects throughout the room, individual and small group work. Resources meant to be printed have that indicated on each page.
This resource would connect well with a textbook or classroom resource for additional practice. Each lesson is meant to be for 10-15 minutes. There is not extension work for advanced students or differentiated work for struggling students. You may want to add this as a supplement or adjust the numbers accordingly based on your student levels.
I use this at the start of grade 4 area and perimeter and have shared this resource with colleagues. Common Core State Standards for grades 3 and 4 listed on the last page of the presentation. I hope that you find it helpful!
