Pre-Assessment Task Directions Spend 15 minutes working individually on this task. Read through the task and try to answer it as carefully as you can. Show all your work so that I can understand your reasoning. Don’t worry if you can’t complete everything. There will be a lesson that should help you understand these concepts better. Your goal is to be able to confidently answer questions similar to these by the end of the next lesson. 2

Collaborative Activity Day 1 - Instructions 6 Cut out all polygons and the 360 ⁰ protractor. Start with the triangle and use the protractor to determine the degree of rotation needed to make the figure look exactly the same as it was in the starting position. Rotate both clockwise and counter- clockwise. Record answers on the recording sheet. Use the ruler to create lines of symmetry. Check the lines by folding to see if the two parts match. Record answers on the recording sheet. Repeat the process with the additional polygons. Groups should complete the summary questions for each section.

Collaborative Activity Day 2 - Instructions 7 Return to your same group as Day 1. Work with your partner to make transformations in the order described. Transformed points should be recorded. Once both graphs are completed, one partner should see teacher for multiple choice answers for each problem. Determine the correct answer for each problem and tape your graphs under the appropriate solutions on the wall.

Plenary Discussion Questions 8 Explain how to use the algebraic expression on the translation. Can you check your answer using the graph? Can you check your answer using the table? What steps did you use in reflecting across a line that was not an axis? How is it different to reflect across just the x-axis? How is it different to reflect across just the y-axis? Does it matter if you rotate clockwise or counter- clockwise? Explain how they are related? Does order matter when doing multiple transformations? Explain how you determined your answer.
