Grade 11 Essential Math Unit 5: Scale Representations
Grade 11 Essential Math Unit 5: Scale Representations
Learning Goal(s):
Unit 5: Scale Representations
1) Solve problems that involve scale.
2) Model and draw 3-D objects and their views.
3) Draw and describe exploded views, component parts, and scale diagrams of simple 3-D objects.
Learning Activities:
Complete the following questions, and make sure to check your answers at the back of the textbook. There is an answer key there. Make sure to ask questions in class if you are not getting the right answers.
____p.215-217 #1-8 (Section 5.1)

____p. 244-246 #1-6 (Section 5.3)
____p. 248-251 #1-6 (Review)
Assessment:
This unit will have two assessment pieces – a project and a test. The test will be based on the review. You will hand in the project by the date of the test. The test and the project will each be worth 5% of your final grade.
