Option #1 (Students choose or are assigned one of the five anchor problems to work on with a group of peers. After collaboratively deciding their approach and solution, students can prepare a poster to show their response.)
Trophy stand
Central High School won the league softball championship game last weekend. The team would like to make a display stand for the trophy. The stand will be a rectangular prism. The players plan to paint the stand white so they can each paint a handprint on the stand in different colors.
The players want to fit each of their handprints on the stand without overlapping with any other handprints. There are 24 players on the team.
Design a display stand that meets the requirements above. What are its dimensions? Show or explain how you found the dimensions using words, pictures, and/or numbers.

The following resources include problems and activities aligned to the objective of the lesson that can be used to create your own problem set.
There is no problem set for this lesson, as the activity will take the whole class period. If there is extra time, spiral in review problems from earlier in the unit or previous two units.
?
(To be completed once student groups have finished creating posters/visuals for their problems and they are posted around the room.)
Choose a problem that you did not solve already and review the work of your peers on their poster.
