CMS WEEKLY LESSON STRUCTURES

Winders / Math 67 / GRADE 6 / Feb 7-11, 2011
UNIT: Unit 6 – Scale Factor
GPS Standard(s)/Element(s): M6M1:Metric and customary conversions within one system.M6M2:a. Measure length to the nearest half, fourth, eighth, and sixteenth of an inch. b. Select and use units of appropriate size and type to measure length, perimeter, area, and volume. c. Compare and contrast units of measure for perimeter, area, and volume. M6G1:c. Use the concepts of ratio, proportion, and scale factor to demonstrate the relationships between similar plane figures. d. Interpret and sketch simple scale drawings.e. Solve problems involving scale drawings. M6A1:Understand the concept of ratio and use it to represent quantitative relationships.
Enduring Understandings: Students will understand that…
· It is important to be able to convert from one unit of measure to the other
· Ratios, proportions, and scale factors are used to solve many problems encountered in everyday life.
· The ratios of corresponding sides of similar figures are constant.
· Scale factors are used to create scale drawings.
UNIT ESSENTIAL QUESTION:
·  Why do we need scale drawings?
