I always have students tackle 2.4 on their own - it is short and simple. This quick chart asks for the most important details out of the scene, complete with Shakespeare's words, the line numbers, and a modern explanation where needed.
* NOTE: The first three questions are from the very end of 2.3 - I use them to model with the students how to fill in the chart, and how detailed I want their answers to be when called for. If 20 minutes seems too long, feel free to modify for your own needs.
