Today I am linking up with Miss Math Dork for her March Math IS Real Life linky. I am in the middle of a geometry math class for teachers (it's one of my last classes for my math endorsement) and we had an assignment to work with area and perimeter with our students. I looked through the chapters we were supposed to base our task on and there was one that compared a 5 x 7 and a 6 x 6 garden plot. Students were given the task to determine which would provide for more square feet of garden. As I'm thinking about how to make this task appropriately challenging for fifth grade, my husband texts me that he has ordered the wood for my new garden boxes. The lights go on and I have my new task.
I am planning to build garden boxes in my backyard. I need to order the wood to build them and we can't decide who has the best plan. Thom wants to build 14 boxes that are 3 feet wide by 14 feet long. I want to build 10 boxes that are 4 feet wide by 16 feet long. Which plan will provide the most garden space?
Lots of great math came out of this task:
- Difference between square feet and linear feet
- Finding area
- Finding perimeter
- Multiplying to determine cost
I also had a lot of great comments:
- "Wait, this is for real? You're making us do your bidding?"
- "Why are we doing your math?"
And my favorite, the note at the bottom of her page...
I don't like weeding, but this math IS real life! In fact, we built the first of our boxes on Saturday.
