II.MultipleIntelligences
- Teach the information in this lesson.
- Then use the information on dilations to complete the following activity.
- Divide the students into groups and have them measure the classroom.
- Each group is working on the same assignment. Having each group work on the same assignment will produce
different diagrams to explain the same information. - Students are going to complete a drawing that shows the measurement of the classroom. They can create a
scale to represent the measurement of the room. - Next, students create a dilation of the classroom where the scale factor is^12.
- Students need to draw a diagram of this and label it with the correct measurements.
- Then, students create a dilation of the classroom with a scale factor of^14.
- Next, students create a dilation of the classroom with a scale factor of 3.
- Then have students complete the area and the perimeter of the room.
- Find a perimeter with a scale factor of^13.
- Find an area with a scale factor of^13.
- Allow time for the students to share their work and any observations.
- Intelligences- linguistic, logical- mathematical, visual- spatial, bodily- kinesthetic, interpersonal, intraper-
sonal.
III.SpecialNeeds/Modifications
- Review congruence transformations that preserve length- translations, rotations, and reflections.
- Define a dilation.
- Define scale factor.
- Review finding the perimeter of a figure.
- Review finding the area of a figure.
IV.AlternativeAssessment
- Walk around and observe students as they work.
- Collect diagrams and use for a classwork or a quiz grade.
Self- Similarity (Fractals)
I.SectionObjectives
- Appreciate the concept of self- similarity.
- Extend the pattern in a self- similar figure.
II.MultipleIntelligences
- Differentiate this lesson by completing a construction of each of the fractals. Ue rulers and measure to ensure
accuracy. - Here are the steps.
- Begin with a segment.
- Divide the segment into three congruent parts.
- Remove the middle part leaving two parts.
- Divide each segment into three congruent parts.
