- Then tell students to use scalar multiplication and the given scale factors to design two new polygons.
- Have students complete the work with the matrices on a separate sheet of paper.
- When finished, draw the two new polygons on the coordinate grid.
- Allow time for students to share their work when finished.
III.MeetingObjectives
- Students will use the language of dilations.
- Students will calculate and apply scalar products.
- Students will use scalar products to represent dilations.
IV.NotesonAssessment
- Collect both the coordinate grid with the dilated polygons and the matrix worksheet.
- Then check student work for accuracy.
- Offer correction/feedback as needed.
