🔵 I can identify, create, and describe scaled copies of figures, using scale factors and understanding that the side lengths change by a scale factor while the angles stay the same.
🟢 I can interpret and create scale drawings, use scales to find actual or scaled distances, and explain how scale affects size and area.
UNIT 1 OVERVIEW
There is no test for unit 1. Grades on this learning target will be based on Lessons and Cool Downs.
Comprehend the phrase “scale factor” and explain (orally) how it relates corresponding lengths of a figure and its scaled copy.
Identify and describe (orally and in writing) corresponding points, corresponding segments, or corresponding angles in a pair of figures.
Unit 1 Lesson 1.1, 1.2, 2.2, 2.3 & 3.2 Unit 1 Lesson 2 PP. Unit 1 Lesson 2 CD.
Recognize that corresponding distances in a figure and its scaled copy are related by the same scale factor as corresponding sides.
Unit 1 Lesson 4.1, 4.2, 4.3, 5.2 & 5.3. Unit 1 Lesson 4 PP. Unit 1 Lesson 4 CD.
Create a scale drawing, given the actual dimensions of the object and the scale.
Unit 1 Lesson 7, & 9.2 Unit 1 Lesson 7 PP. Unit 1 Lesson 7 CD.
Reproduce a scale drawing at a different scale and explain (orally) the solution method.
Unit 1 Lesson Lesson 10 & 9.3. Unit 1 Lesson 10 PP. Unit 1 Lesson 10 CD.
Interpret scales expressed without units, e.g., “1 to 50,” (in spoken and written language).
