III. Instruction and Assessment

1. Connect: Connecting to the Concept Experientially

Objective: Students recognize that necessary conditions exist everywhere.

Activity: Create a visual that shows what is NECESSARY for a high school student to be eligible to participate in athletics.

Assessment: Student participation and contribution to the group.

2. Attend: Attending to the Connection

Objective: Each group will compare what they think is necessary with the other groups.

Activity: Each group shares their visual. The whole group discusses their findings.

Assessment: Individual attention and participation in the discussion.

Assessment, Phase One, Level of Engagement, Fascination:

3. Image: Creating a Mental Picture

Objective: Students begin to identify the uniqueness of rectangles, rhombuses, and squares.

Activity: Students look around the room and find surfaces that are rectangles, squares, or diamonds in shape. Have them explain what makes it the shape that it is and identify any differences between shapes.

Assessment: Individual student participation.

Assessment, Phase Two, Seeing the Big Picture:

4. Inform: Receiving Facts & Knowledge

Objective: Define rectangles, rhombuses, and squares. Identify necessary conditions for these special quadrilaterals.

Activity: Teacher defines rectangle, rhombus, and square and proves the theorems representing the necessary conditions for each. Teacher works various examples. Students work practice problems.

Assessment: Students' attention and participation during the instruction. Monitor student's ability to work sample problems.

Assessment, Phase Three, Success with Acquiring Knowledge:

5. Practice: Developing Skills

Objective: Students will be able to define rectangles, rhombuses, and squares and identify their necessary conditions.

Activity: In small groups, prepare a visual(s) that defines rectangles, rhombuses, squares and identifies their necessary conditions. Independent practice problems.

Assessment: Participation in the group. Accuracy and completion of visuals and practice problems.

Assessment, Phase Four, Success with Acquiring Skills:

6. Extend: Extending Learning to the Outside World

7. Refine: Refining the Extension

8. Perform: Creative Manifestation of Material Learned

Assessment, Phase Five,Performance, Creative Use of Material Learned:
