- Students can review information on rotations here.
- Then they can work to manipulate and create different rotations.
- There are directions on the screen which help them in accomplishing this task.
- You can use this as extra practice or for a student who needs remedial work in this area.
IV.NotesonAssessment
- Assess the student rotation scenes.
- Did the students accomplish the task of showing the skateboarder in different rotations?
- If not, what would have worked better?
- Did the students expand on the assignment?
- Were the students able to explain the use of rotations in their scene?
- Provide students with feedback on their work.
Composition
I.SectionObjectives
- Understand the meaning of composition.
- Plot the image of a point in a composite transformation.
- Describe the effect of a composition on a point or polygon.
- Supply a single transformation that is equivalent to a composite of two transformations.
II.Cross-curricular-MoviePosters
- Have students watch the video first.
- Discuss the elements of a great movie poster.
- What works and what doesn’t work.
- Tell the students that their job is to create a movie poster for a new movie.
- You can use one that is popular with the students at this time or use an old favorite like “Star Wars” that
probably all of the students have seen. - Tell the students that they are going to create a poster for this movie using the elements of transformations.
- There needs to be a use of rotation, translation and reflection in their posters.
- Students can work in pairs on this task.
- Have students share their work when finished.
III.TechnologyIntegration
- If possible, have the students watch this short video first.
- http://www.thefutureschannel.com/dockets/hands-on_math/movie_posters/
- You want the students to be looking for elements or transformations in the posters.
- Students are going to use this information in the activity.
IV.NotesonAssessment
- Assess student work based on the student’s use of transformations.
- Are there rotations in the poster?
- Are there translations in the poster?
