Exponents

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.
