II.MultipleIntelligences
- To differentiate this lesson, begin by teaching all of the content in the lesson. The content will be necessary to
do this activity. - Begin the activity by giving students the coordinates of one triangle on the coordinate grid.
- Have students use colored pencils and a ruler during this lesson.
- Request that the students graph this triangle on the coordinate grid in one color.
- Then have students take this triangle and draw each of the following by using this triangle as a starting point.
- Students are going to have multiple pages of diagrams when they are finished.
- One page consists of a translation or slide.
- One page consists of a reflection or flip.
- One page consists of a rotation or turn.
- One page consists of a dilation.
- Stress the point that a dilation is the only image where the two images are not congruent. The two images are
similar. - Intelligences- linguistic, logical- mathematical, visual- spatial, bodily- kinesthetic, interpersonal, intraper-
sonal.
III.SpecialNeeds/Modifications
- Write all new vocabulary words on the board.
- Request that students copy these words in their notebooks.
- Review the meaning of clockwise and counterclockwise.
- Review the difference between things that are congruent and things that are similar.
IV.AlternativeAssessment
- Collect the packet of diagrams/drawings that the students have created during this lesson.
- This packet will allow you to assess student understanding of the information presented in this lesson.
- If letter grades are used, than a classwork or quiz grade can be given for this packet.
