Finding the area of an irregular shape can be difficult. It takes some logical thinking, especially when missing sides are thrown in! We began by figuring out the missing dimensions. We used the opposite sides to help us with this. Once we did this, we had to find regular shapes (squares and rectangles) within the irregular shape. Once we found the area of those, we could add them together to get the area of the whole shape. Hopefully the pictures help explain our process. This is definitely more difficult than finding the area of regular shapes!
I'm a wife, mother of two, and 4th grade teacher who is totally in love with her job! I teach math and science to roughly 40 kids a year. I've tried to model my classroom after this quote by Elliot Eisner - "When the joy is in the journey, the journey will be pursued." I feel very fortunate to work in an amazing school district, where it is commonplace to push students to their full potential and settle for nothing less. I truly feel blessed!!
