This Google Slides Activity includes 12 unique slides that help students practice choosing the correct formula for and finding the total area of several regular and irregular geometric shapes. Students are asked to find the area of very basic, whole number dimension polygons, and then deconstruct/decompose several shapes made of regular polygons and find their area as well.
The slides become more difficult as students progress through the activity, starting with simple parallelograms and triangles and ending with irregular polygons that must be separated into regular geometric shapes and include decimal measurements. Students will need prior knowledge about the area formulas for parallelograms, triangles, and trapezoids, as well as ideas for separating shapes into smaller, recognizable parts.
An easy way to differentiate or modify this activity would be to make some slides optional or extra credit. Teachers could also ask their students to complete some of the 12 slides, not all, providing a choice for which problems they solve. Additionally, another way to modify would be to allow calculators to be out and used during the activity, as well as providing students with an answer bank of the 12 area answers and allowing them to check their answer with the answer bank.
I have used this activity in my 6th grade classroom and all abilities of students enjoyed the challenge. There is no prep required other than saving the activity to your Google Drive and assigning it via Google Classroom or providing your students with a link to the activity.
