1 Warm Up - 8 minutes

2 Let's Play - 30 minutes

For work time, students participate in a collaborative game that provides practice with applying the Pythagorean Theorem to solve problems.  To set up the game, I gather 10 containers and number the lids from one to ten.  Then, I cut the game questions up and place them in the corresponding containers. Before the game starts, I ask the students to go to the next page in their journals, title the page "MI: Pythag Theorem" and number from 1-10.

Students groups (of 4 or fewer) select one team member to be the “runner”.  When the game begins, each runner takes ONE container and brings it to the group.  The group answers the question in the container and then returns the question and trades it with a container they have not yet seen. Once all questions have been answered by the group, the runner brings his/her group’s answer to me to check. Depending on time remaining, I either tell the runner the number of questions they have correct, or I tell them to focus on particular answers they have missed. The first team to answer all 10 questions correctly wins, but all groups continue to work until they have ten correct answers.

To add to the energy of the game, I play the Mission Impossible Theme song on repeat found at  http://w3.uwyo.edu/~dwwilson/music.htm under TV Shows.

3 Ticket Out the Door - 7 minutes

Once the 30-minute game has ended, I distribute a 3 x 5 note card to each student for them to create their "Ticket Out the Door" response.  I display the question and ask students to work independently to solve the problem.  Their responses provide essential feedback to me about student approaches and proficiency levels with applying the Pythagorean Theorem to solve problems.  I provide additional time in the form of before and after school tutoring for students who need it.
