This resource includes 19 learning targets with specific success criteria and student reflection rating scale. Learning targets are grouped by topic (transformations, circles, right triangles, etc) and include “vocabulary to master” for each topic. This is a great resource to include in student binders of interactive notebooks. Use these as a teacher resource to write your daily learning target on the board. This resource is editable for your ease of use.

Many students learn the process for simplifying square roots without learning the why. This lesson is to help students connect area of a square to perfect squares and simplifying square roots. •Lesson Plan with guiding questions •2 page student worksheet •Answer key for student worksheet •Figures A – L for student work

Have little time to spare in class? Use this resource to let students review basic vocabulary and facts about circles on their own. This resource includes: Pages 3 – 4: Student handout Pages 5 – 6: Answer key Pages 7 – 23: Power point slides that can be shared with students so they can begin reviewing information and formulating their own definitions/facts. Print them out, project them, or post them on a platform.

Get your students thinking, talking, writing, and using vocabulary with this “Guess Who” activity. This is a great activity to do with any group of words – just change out the word list. It builds a deep understanding of the vocabulary by using comparison and contrast, encourages interaction and discussion, and encourages writing in math class.

This resource includes several activities that focus on “common mistakes” that students make with equations of circles. Each activity is described below: Activity G: Writing equation given the center and a point on the circle Activity H: writing equation given the center and a point on the circle Activity I: writing equations given the endpoints of horizontal or vertical diameter Activity J: writing equations given the endpoints of a diagonal diameter Use this as targeted practice, as a stat

This resource includes several activities that focus on “common mistakes” that students make with equations of circles. Each activity is described below: Activity D: radius – all circles are centered at (-1, -1) and have various radii Activity E: radius – all circles are centered at (5, -2 ) and have various radii Activity F: radius – all circles are centered at (-3, 1) and have various radii Use this as targeted practice, as a station activity, or for intervention/extension.

This resource includes several activities that focus on “common mistakes” that students make with equations of circles. Each activity is described below: Activity A: signs of the center – all circles are centered at variations of (2, 3) and have a radius of 2 Activity B: signs of the center – all circles are centered at variations of (2, 1) and have a radius of 2 Activity C: signs of the center – all circles are centered at variations of (4, 2) and have a radius of 1 Use this as targeted prac

Need to maintain solving equations in Geometry class? Need to provide extra practice for struggling students? Use this document to provide solving strategies (in the form of hints), guided problems, mathematical reasoning (students providing steps to guided problems), practice, and answers provided for self checking. This resource includes: •Two page student worksheet with answers

Here are notes that will work in notebook or interactive notebook. These notes include alternate interior angles, corresponding angles, and vertical angles. Students can then use their knowledge of these 3 angle types to prove many other angle relationships (ex: alternate interior angles) and Geometric properties (triangle sum theorem). This resource includes: 2 pages of notes (alternate interior angles, corresponding angles, and vertical angles)Answer keyDon’t forget to have the students color

My students often confuse reflection and rotation rules. “Which one changes order? Which one changes sign? Which sign do I change?” This activity was developed to allow students to make sense of the rules. Students will identify changes in pattern between two sets of points and use this information to write a coordinate rule. They will then graph a pre-image and image and use the graph to determine the type of transformation being performed. Class discussion and summary notes help the students c

Students will practice composite transformations in a structured format. Each problem has student perform the first transformation and write the coordinate rule then perform the second transformation and write the coordinate rule. This activity would be good practice for students beginning to learn composite transformations or to help struggling students master the concept. This activity includes translation, reflection, rotation and dilation. This resource includes: 2 page student documentAnsw

This resource includes: •Treasure Hunt A: practice reflecting over x-axis, y-axis, horizontal lines (ex: y = 2) and vertical lines (ex: x = 3) •Treasure Hunt B: practice reflecting over x-axis, y-axis, horizontal lines (ex: y = 2) and vertical lines (ex: x = 3) •Treasure Hunt C: mixed review including practice reflecting over x-axis, y-axis, horizontal lines (ex: y = 2) and vertical lines (ex: x = 3), translating, and rotating •Answer keys for each treasure hunt Basically these are 3 worksheets

This resource allows students to practice writing coordinate rules of transformations. Each problem has students write the coordinates of the pre-image and image points, correct coordinate rule, and identify the type of transformation being performed. The last page has students performing error analysis with coordinate rules and providing evidence to support their reasoning. All transformations (translation, reflection, rotation, and dilation) are represented in this resource. This resource inc

This resource allows struggling students to reengage in dilating geometric figures while improving their understanding of the material. Each problem has students select the pre-image and image, make sense of the correct coordinate rule, and identify misconception(s) in an incorrect rule. Finally students practice writing coordinate rules for themselves. This resource includes: Student documentAnswer key

Are your students having a difficult time performing a sequence of transformations? Perhaps this cooperative learning activity will help. This resource focuses on the transformations of translation, reflection, and rotation. Dilation is not utilized in this activity. Students will work interchangeably with coordinate rules, graphs, and descriptions. This resource includes: 4 pages of student worksheetInstruction sheet for cooperative learning groupsClosing discussion ideasAnswer key

Teaching transformations in Geometry? This resource will help your students investigate reflecting over the x-axis, y-axis, x- and y-axis, and over a line (x = -1). Students will graphically complete the reflections and then look for patterns with the results points (connecting to coordinate rules). This resource includes 4 student pages (reflecting over the x-axis, reflecting over the y-axis, reflecting over the x- and y-axis, and reflecting over a line (x = -1). Answer sheet is provided.
