Accessing Shakespeare's Language
One of the most common hurdles for students to overcome in their initial exposure to Shakespeare is the difficulty of the language, and this is a helpful activity that can occur early in your Twelfth Night study.
Make enough copies of Orsino's opening speech (I.i.1-15) so that you can divide your students into pairs, and each pair will have a copy of the speech. They're not going to get a full copy, though -- you're going to cut it up into individual words and phrases, and then put each set into a Ziploc bag as part of preparing for class.
Give each pair a bag, and ask them to assemble the speech, based on what they think he might be saying. You can help them by saying that the speech is about the disappointments of love. You can also expose them to iambic pentameter, so they'll know that each line should have ten syllables. Telling them that the first letter in each line is a capital letter may also help.
As you circulate the room, monitoring, you'll want to have a correct copy of this speech in hand to help students who are having a hard time figuring out which word or phrase goes where. Give your students time to make mistakes and do some thinking, though. Don't give the answers away too quickly. Also, don't let them see the correct copy of the speech.
Give students about 20 minutes to work on this. After time is up, put the correct speech up on your document camera, or distribute correct copies for students to look at. Ask students to share with the whole group how close they got to having the correct text of the speech.
The purpose of this activity is to get your students accustomed to the nuances of Shakespeare's language. Dealing with Renaissance language in this format will make reading the play much more accessible to them than if you had just jumped right in to Act I, Scene I in a traditional read through.
