Sod in the ParkI completely forgot to take pictures of my students with this task, but it was such a great math task that I am going to post anyway. We are pretty much right in the middle of testing right now, but I still have a few math standards to cover before we test math. I am also just coming back after a student teacher and wanted to get my students back into math with me, so I planned a task that allowed my students to use a wide variety of mathematical skills and required some real mathematical thinking. Here's the background information:
I was really surprised by the number of students who had no idea what sod is. After reading the background story and talking about what is happening in the story, I passed out the worksheet below.
The comparison question was required and the two questions dealing with the cost were included for those who finished early or needed a more challenging component to the task. The task requires quite a few math skills. I thought my students would use all of these:
- total area of the park and total area one roll of sod will cover
- dividing the total area by the square footage per roll to find the number of rolls it will take to fill the park
- comparing each company's cost for the same amount of sod
- multiplying whole numbers and decimals
It was great to see my students try and tackle this from many different angles. Our whole hour of math was filled with productive talk and difficult problem solving. For those students who blazed right through the comparison task, the last two problems on the bottom provided some more difficult problem solving opportunities for them.
If you would like to use this task, you can grab the file with the story and the worksheet here.
Happy Problem Solving!
