Area & Perimeter of Rectangles and Squares

UPDATE: I uploaded instructions on how to set up the flip-book at the bottom of the post. 

Yesterday, we began our unit on Area and Perimeter. I always put somewhat easy examples in foldables so that students can have the basic understanding of how to solve a problem. In this foldable, the problems are relatively easy because I wanted to use this with my basic special education students as well. (I also think that the colored papers that I chose are on point! :))


We completed the Rectangles and Squares flap today in class. I actually had the students solve for all missing sides of the rectangles independently because they have seen special right triangles throughout the semester. More than half of my students figured out the area and perimeter by themselves before I even started the notes. The most common mistakes were on questions 1 and 3 when students had to find the perimeter. Some students wanted to say perimeter = 83 instead of (4 + 43).


After finding the area and perimeter of rectangles, we moved on to squares. Squares went by so fast because we practiced many times with squares in our special right triangles unit. Some kids were done within 5 minutes of me telling them to try to complete examples 1-4. 


After the notes, I had students complete the following Area & Perimeter Partner Activity. I have students work with a partner and they had to both choose a separate column to complete. I really like partner activities because it eliminates cheating in my classroom because students can check their work with the partner to make sure they both got the same answer. If they don't get the same answer, they start to collaborate to check each others work. It also amazes them that two completely different problems could result in a common answer! :)

  1. I am super excited to use the flip book in both my academic and Pre AP geometry classes. What did you put in the facts section on the Formulas page?

  2. For rectangles, I wrote that you "may" see pythagorean theorem or special right triangles (so we did a little diagram in the facts section). For squares, I wrote that a square can always be made into 2 45-45-90 triangles (we wrote down the chart). I will have to look tomorrow to see what I wrote down for the other facts. I completely forgot :)

  3. Could you put on some directions....I am a little confused with how to set it up. It will be great for my math class. Thanks!

  10. Any chance you have an editable version of this? I would like to create a simpler version as we have not covered special triangles as of yet.
    Thanks! amiklavic@oldfortschools.org

  11. Hello, Thank you so much for sharing your activities, they are great!! I tried printing double sided and fliping on the short side but it seems as if the file you posted has them out of order. They go Rect. Square parallelogram, rhombi, triangle, trapezoid, and formulas. I WOULD love to use this coming up this week but don't think I can without some instructions. Could you please help me. Thanks, Laurie Carver email: laurel.carver@lz95.org
