Here’s PreCalc H solving tricky inequalities in groups (tricky because some were the absolute value of rational functions). They are fantastic at group work. Asking questions of each other, helping each other out. It’s great.
To preview the Complex numbers unit that we’ll be starting tomorrow, I asked them to recall everything they knew about the complex numbers. I called on each one (randomly with Popsicle sticks). Some really interesting confusion between complex numbers and irrational numbers in both PreCalc H classes.
