Give guidance and feedback to students' plans, encouraging, refining, and helping them to be responsible for their own learning. Maintain high expectations for completion of chosen options. Summarize by reviewing the whole, bringing students "full circle" to the experience with which the learning began.

Student constructions of 3-D shapes.

Objective: To show application of geometric knowledge.

Activity: Using teacher-made task cards, showing the outline of several geometric figures, students work in pairs to try to replicate the drawing on the task card. Then, the students must add one detail of their own (make a 3-D construction or alter shape, etc.).

Assessment: Evaluate each pair's construction. Is it formed from the task card? Has it been changed?
