Unit 1 Day 1

Welcome to Ms. Samaras Common Core II Class!

Classroom Norms and ExpectationsWarm UpsHomework Stamp SheetsGroup Work and RolesSchool SuppliesOther ExpectationsSchool PoliciesFood/DrinkEmergencies Warm ups occur at the beginning of each day and should be completed in the appropriate block of their warm up sheet. Mr. K will check off warm ups after designated time, usually 10 mins. If you miss a day, write ABSENT in that days box when you return. Warm up sheet should be kept in folder in basket on desk. Warm ups will be checked at the end of each week (and randomly). After graded, past Wus should be kept in binder.

Each student will have an individual HSS and it must be kept in your binder at all times. At the beginning of class, I will check hw during Warm ups. HW is graded on completion (100, 50, 0). Late homework is not accepted but all hws are required in your binder.

Binder checks will occur randomly throughout the semester. It is important that you bring your binder everyday and keep up with all notes, even if you are absent. Binder checks may be done by teacher or by classmate. Binder checks may or may not be announced as well as the contents looked for. While no specific order is required, binder should be organized in a way that is easy to look through. If I am not quickly able to locate items, they will not count for your binder check.

Comment on how groups worked today. You are responsible for the members of your group. At times, you will be given a group evaluation to fill out about your work ethic as well as the other members of your group. Groups will be changed approximately once a unit. Each member will have a role everyday. Most days, you may choose your role by picking the card from your basket. Not every role will be used everyday. Teacher reserves the right to assign roles and it is recommended that you circulate roles each day. More on roles in a second.

Be respectful of your classmates and the teacher. Be responsible for your actions and for bringing your materials. Participate in discussions.2Remind 101To get reminders and announcements text @mssamara1 to 919-800-0736 Group RolesTime Keeper/RecorderKeep track of timeRecord Group answersResource ManagerGet supplies for groupReaderRead instructions OUTLOUD or assign readingsSpy MonitorWhen your group is stuck, check with other groups or teacherIntroduction to TransformationsAndTranslationsUnit 1 Day 1Warm UpMatching Card GameEach of you has been handed a card with a figure plotted on a coordinate plane.

Find your classmate who has the matching figure.

Once you find your match, sit together and write a quick description of how your figures have been changed. Be as descriptive as possible! Use the Monday block of the Warm Up sheet on a desk

Once all matches have been found, you and your partner will describe your cards to the class.

EndTransformationsDefinition: A Transformation is a change in the position, size, or shape of a geometric figure.

Think About The Situation

InvestigationIn this lesson, you will learn how coordinates can be used to transform shapes.

You will investigate coordinate representation of rigid transformations that provide a way to reposition figures in a plane without changing the shape or the size of the figures.TranslationDefinition: A Translation (slide) is a transformation that moves points the same distance and in the same direction. A translation in the coordinate plane is described by a vector.

Preimage and ImageThe preimage is the original figure. Denoted as A

The image is the figure after a transformation. Denoted as A or A prime (This is called Prime Notation)

Group WorkA translation, or sliding motion, is determined by distance and direction. By looking carefully at a simple shape and its translated image, you can discover patterns relating the coordinates of the shape and the coordinates of its image.

Time Keeper: 15 minutesResource Manager: Problem 2 and 3 Worksheet (1/member)

Question 2v

Question 2v

General RuleCompare the transformation rules you developed for Part d of Problem 2 and for Parts c and e of Problem 3. As a group, write a general rule that tells how to take any point (x, y) and find its translated image if the preimage is moved horizontally h units and vertically k units. Compare your rule with other groups and resolve any differences.General Rule(x, y) (x + h, y + k)

Describes a translation of h horizontal units (+ Right, - Left)k vertical units (+ Up, - Down)

ExampleWrite a description and rule for the following translation

Vector NotationVector notation is another way to write rules of translations.

A vector is written as h = left/rightk = up/down

Marching Band ActivityResource Manager: Grab a worksheet for each group member.

Reader: Read instructions out loud to group.

Time Keeper: You have _______ minutesAssessmentQuickWrite: On a small piece of paper, summarize what you learned today in 2 minutes. You may include pictures or symbols if needed. Post on board when finished.

Homework: Worksheet
