1. Warm-up: Grab a piece of graph paper and patty paper
- On a coordinate plane, plot the triangle made by the ordered pairs A:(3,1) B:(3, -2) and C:(6, 1)
- Transformation 1: Translate left 2 units and down 3 units
- Transformation 2: Rotate 90 degrees clockwise about the origin
- Transformation 3: Reflect across the x-axis
*Challenge: Can you transform the original triangle to its ending position in a different way? Write instructions for doing so.
2. Lesson 6.1.3 Rules of Transformations
- Objective: I will begin to generalize ways to quickly translate and reflect shapes. I will write those generalizations as "rules"
- Problems 18 and 19 ask you to make generalizations about translations using addition.
- Write a rule that a 7th grader could use to understand how a translation affects the coordinates of an ordered pair.
- Problems 20 through 22 ask you to make generalizations about reflections using multiplication.
- Write a rule that a 7th grader could use to understand how a reflection affects the coordinates of an ordered pair.
- Problems 23 and 24 in teams
Homework: Lesson 6.1.3 R/P skip #32
