Snow Day Math

Today there’s a storm and busses are cancelled so we had fewer than normal students. In grade 10 we worked on a task about rectangles. Each group needed to choose a number between 30 and 70 and that would be the perimeter of each rectangle made. They needed to make a list of all the possible rectangles, and then make the rectangles and calculate the area.

Next we cut out the rectangles and used them to graph the relationship between side length and area.

It was neat to see the quadratic relationship show up, and how the optimal area would be the square, which for a perimeter of 42 would have side length 10.5

It was a pretty fun task to do on a snow day, first day back from holiday.
