Friday in grade 10

We explored the 3act task to find out which rectangle had the biggest area. Many of us thought that the biggest area would be a square. We didn’t notice that the rectangle didn’t always have the same perimeter, so this case was very different to our experience from grade 9.

We made tables and looked for patterns. We know how to calculate area (length times width), and we noticed how the length and width were changing.Some groups noticed that the area has a constant 2nd difference, so we know it’s not linear.some of our groups started to use variables, and develop expressions.

We will come back to these explorations in the future. Good work this week grade 10s. There will be a practice sheet posted to the google classroom, along with the quiz solutions.
