Provide a metaview, lifting students into a wider view of the concept. Use another medium (not reading or writing) to connect students' personal knowing to the concept (i.e. visual arts, music, movement, metaphor, etc.) Involve learners in reflective production that blends the emotional and the cognitive.

Group uses graphing calculator to discover effects of changes to amplitude and period.

Objective: The students will describe amplitude and period and the effects they have on the sinusoid graph.

Activity: The students will help the teacher construct the sine and cosine graph with the coordinates from the circle graph. The students will work in groups with the graphing calculator and discover patterns in changing the amplitude and period. (A teacher-designed worksheet will guide the students in this activity.)

Assessment: The ability of the students to discover the effect of changing the amplitude and period of the graph.
