When you find the right desmos activity at the right time with the right class, it’s magical. The conversations that I overheard them having when working through this activity (exploring amplitude and vertical shifts of trig graphs) were just fantastic.

Here’s a student sketching out the maxes and mins of a trig graph so that they could find the amplitude and midline (all terms that they haven’t been introduced to yet) so they could graph y=a*sin(x)+b.
