Every activity in your session needs something different. A check-in needs nothing at all. A case discussion needs the case. Open the Materials tab. Under each activity, you see what it needs, chosen with the activity. A handout to read, a worksheet to fill in, or a canvas for the wall. Click Make, and it's built for that activity, under its own name. The worksheet knows the handout next to it, so nothing is said twice. Markers and sticky notes, you simply tick off. And if a few are still missing, make them all in one go.
