1.) 35n + 5s 2.) 27 + 45u 3.) 28g +4x Homework: Study Over Notes Quiz on Friday

1. Make sense of problems and persevere in solving them. 4. Model with mathematics. 5. Use appropriate tools strategically. 7. Look for and make use of structure. 8. Look for and express regularity in repeated reasoning. MCC8.G.1 Verify experimentally the properties of rotations, reflections, and translations: a. Lines are taken to lines, and line segments to line segments of the same length. b. Angles are taken to angles of the same measure. c. Parallel lines are taken to parallel lines. MCC8.G.2 Understand that a two‐dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them. Understand congruence and similarity using physical models, transparencies or geometry software. I can use the properties of translations, rotations, and reflections on line segments, angles, parallel lines or geometric figures. I can show and explain two figures are congruent using transformations (explaining the series of transformations used) I can determine the new coordinate of a figure given a dilation, translation, rotation, or reflection. Learning Targets

Translation, 4 units to the right and 8 units down. Writing About Math Name the pre-image. 2. Name the “new” image. 3. Describe the following transformation, using vocabulary terms ABC A’B’C’ Translation, 4 units to the right and 8 units down.

Pairs: Finish Translation handout from Yesterday *skip question 4

Translation “side with 5 rectangles” Date your graphic organizer Translation “side with 5 rectangles” Directions: Write down the coordinates for PQRS in the space provided. Now Write down the points for P’Q’R’S’ in the space provided. Think-Pair-Share: What do you notice about the x coordinates and the y coordinates from the pre-image and the image?

Describe the translation. (x,y)--- (x+6, y-2). I can use the properties of translations, rotations, and reflections on line segments, angles, parallel lines or geometric figures. I can show and explain two figures are congruent using transformations (explaining the series of transformations used) I can determine the new coordinate of a figure given a dilation, translation, rotation, or reflection. Directions: Now look at (x,y)--- (x+6, y-2). This is known as a translation rule. A rule tells you what to do or series of steps to follow. Describe the translation. (x,y)--- (x+6, y-2). Individually: complete the remainder of the translation handout.

Reflection across the y- axis Writing About Math 1. Name the pre-image. 2. Name the “new” image. 3. Describe the following transformation, using vocabulary terms CDEFGH C’D’E’F’G’H’ Reflection across the y- axis

Reflections in the Plane Activity Independent Practice Reflections in the Plane Activity Additional Resources Needed: Patty Paper, ruler or Mira

Exit Ticket: “Self Reflection” Turn your first/last name Into the correct folder with today’s date King/Queen- I can explain this to someone else because I truly understand translation and reflection More Practice- I need more practice, even though I believe I understand HELP!- I AM LOST!!
