Exponents

October 10, 2019

Grade 9s explored exponents today, and made connections between exponents and the area and volume concepts we have been looking at.

We are looking at what exponents of 2 mean, and what exponents of 3 mean. We also are looking at what happens when there are coefficients inside brackets that are raised to a power.

We worked on filling concept circles with different representations.

And then “levelled up” to using 2 variables (toothpicks and skewers)

We recognized that expressions like x^2y would represent the volume of a square based prism with dimensions of x,x,y.

Some of us took this farther to explore what the area of such a prism might be.

Lots of learning and lightbulb moments today! Good job grade 9s.
