Since my previous blog post on Making the Most of Math Instruction, it was time for a general review of area and perimeter before the chapter test. Our math program already has a built in math review at the end of each chapter. I do use it, but it really is not enough. So instead I have 3 quick and easy ways to review area and perimeter.
Area and Perimeter Hunt
One of the hardest concepts that students must tackle is the idea of shapes that either have:
- same perimeter, different area
- same area, different perimeter
- same area, same perimeter
So here is a way to combine some hands on with practical and quick practice. Each student receives a bag of foam tiles (I use the ones that came with the math program) and one index card. These were my instructions:
- pick either 8, 10, 12, 14 or 16 tiles
- make a rectangular shape with those tiles
- record your perimeter and area on the index card
Once all the students had done this, the fun began. I had the students now walk around the room and search for another shape they thought had the same area, but different perimeter. Once they found it, they had to record the other students name on their card. Then, I had them find a shape that had the same perimeter, but different area and record that student’s name. Finally, I had them search for a perfect match: same area, same perimeter. It can be a very noisy activity, but here’s a helpful hint. Tell them that they are in an art museum, each rectangle is a masterpiece, so no touching and use quiet museum voices. It works like a charm!
It was fascinating to watch how they were able to eyeball a shape and determine whether it was worth investigating and counting the perimeter or area. But at the same time, I was assured that they were actually practicing finding area and perimeter as they tried several different shapes until they found the one they needed to record on their index card.
The final step was to ask a few students who their match was. When a student volunteered, I asked the matching student if the measurements were correct. All in all, great fun, great practice and it took no more than 20 minutes.
Area and Perimeter Game
I developed this game last year also as a review and so now it was time to bring it out again for some quick fun and practice. This particular game has 8 versions.
★ Set A: Find the perimeter using line grids.
★ Set B: Find the perimeter using measured sides.
★ Set C: Find the missing length given the perimeter.
★ Set D: Find the area using squares.
★ Set E: Find the area using using measured sides or the formula Length x Width.
★ Set F: Find the area of connected rectangles and squares using the Distributive Property of Multiplication.
★ Set G: Find the perimeter and area using measured sides.
★ Set H: Find the perimeter and area using squares.
The same game board is used for all 8 versions (so I printed out an additional 7 more). I had already preassigned students to a particular level depending on those who needed some more basic review to those who needed to be challenged. We spent about 20 minutes playing the game which was enough for at least one round for each group. More information on the game can be found HERE in my TpT Store.
Area and Perimeter on Google Slides
If you’ve read some of my previous blog posts, you know I have a cart full of Chrome Books. I have been putting them to good use by developing practice pages with Google Slides. I made a few quick slides like the one shown below in which the students had to work on a real-world situation.
They were given scratch paper to use. Not only do I want my students to practice area and perimeter, but I also want them to practice answering these questions on a computer in a similar fashion to online testing which they will be facing in a few weeks! In this particular Google Slides review, I prepared 4 slides.
I also have a Perimeter of Shapes and Area of Shapes resource available in my store that is Google Apps Ready! They each include 14 interactive problems increasing in difficulty based on Bloom’s Taxonomy.
Once the students were done with the slides, they were free to move onto the actual textbook practice review, which they finished at home as homework (and also used as a study guide).
There you have it. Three quick and easy ways to practice area and perimeter. Each practice session took between 20 minutes each, which fit perfectly into my math block.
