Design

=Design Phase II=


 * 1.** Scope of Project-Writing and Solving Proportions

A. Goal- Students will be able to write proportions and solving them in real world situations.

B. Audience- 8th grade Pre-Algebra students

C. Design Time and Milestones- Thirteen 40 minute periods


 * 2.** Delivery

A. Content- The lessons will cover the knowledge and skills needed to apply proportions in real world situations.

B. Method- This will be a mastery learning, with quizzes and activities used by the teacher to determine mastery.

C. Training Time-Thirteen 40 minute periods

D. Problems and Oppertunity-We need at least one sunny day to do the outdoor activity because of the need for shadows to complete the activity. Any early dismissals, assemblies, or fire drills would prolong the training time.

Students will be able to write ratios three different ways 100% of the time after one forty minute period. Students will be able to write and solve proportions using equivalent fractions 100% of the time after one forty minute period. Students will be able to solve proportions using the cross products method 100% of the time after two forty minute periods. Students will be able to draw/create similar figures using Geometer's Sketchpad 100% of the time after one forty minute period. Students will be able to identify simliar and congruent figures using ratios 100% of the time after two forty minute periods. Students will be able to find unknown side lengths of similar figures using the proportions formula 100% of the time after two forty minute periods. Students will be able to find the height of specified objects using their shadows and proportions formula 100% of the time afer one forty minute period. Students will be able to find the height of specified objects using a mirror and proportions formula 100% of the time after one forty minute period.
