Parallel and Perpendicular Slope Exploration
Perpendicular and Parallel Slope Exploration gives students a chance to discover the relationship of slopes of parallel and perpendicular lines. They will use Desmos slider bar tools to do so. (Click here to see an example of how slider bars work.) Students will record their discovered parallel and perpendicular equations in tables. The tables are followed by leading questions about slope relationships and check for understanding problems. To conclude the activity, teachers can provide students

Circle Similarity Investigation for Google Classroom
Given 4 pairs of circles centered at the origin, students will explore that all circles are similar. To do this students will find the radius of each circle, then calculate the ratio of the areas and circumferences. On the 5th slide, students are asked to draw their own circles not centered at the origin to see if their discoveries still hold true. At the end, students will be asked to compile all their data in order to draw conclusions to prove all circles are similar. What is included:Editabl

Trigonometry Playdough Mats
Angle of Elevation and Angle of Rotation
In these two playdough mats, students use playdough to practice their Angle of Rotation and Angle of Elevation skills. Because the use of playdough is “big and bold”, the teacher can easily and formatively assess student understanding.
The Angle of Rotation mat has students start with color coding the initial side and terminal side of an angle. It then moves students through creating both positive and negative angles of rotation, as well as angles a

Proof Tips Foldable Notes
Students struggle with proofs for many reasons. Often, when given information, they do not know where start. Students need to think that if they are proving triangles are congruent, “how can I use SSS, SAS, ASA, or AAS”. If they are showing lines are parallel on a graph, “how can I use slope”, etc.
This resource can be used a variety of ways to help students determine where to go with the given information. Pages 3 & 4 can be given to students as a handout. Pages 5-8 are designed to be used

Triangle Properties Click and Reveal
Click and Reveals are a great way to introduce or review a topic or a unit. The PowerPoint is projected in slide show mode on a screen. Students compete in teams to answer the questions using their resources (book, internet, notes, each other). When they have an answer, they send one member up to the teacher to check accuracy. If the student is correct, they may click the question to begin to reveal a picture. WARNING: Students can get very competitive with this activity! Once all the quest

Great fall activity! In this STEAM activity, Band students and Geometry students will collaborate to learn how transformation geometry applies to marching band.
Marching bands use transformations to map out their show on the field. The coordinates that are used are similar to those that are studied in Geometry, and the football field is similar to the coordinate plane. In this interdisciplinary activity, marching band students are paired up with Geometry students in order to learn from each o

Dilations: A Student Investigation
For this inquiry activity, students create their own design on a coordinate plane and use this design to explore properties of dilation. They will be asked to shrink and expand their design by a given scale factor, compare the coordinates of each design, and finally be given an opportunity to prove the properties of similarity and dilation on a coordinate plane. Students will use the distance formula to demonstrate corresponding sides are proportional and a protractor to demonstrate correspondi

Dot and a Line: A Romance of Lower Mathematics (Anytime Activity)
This Anytime Activity is designed to complement the classic musical composition “Dot and a Line: A Romance of Lower Mathematics” that was created in 1965. Questions keep students accountable to paying attention the the narration. At the end there are questions such as “Relate the romantic story of the dot and line to another romance you have seen in a story, poem, book, or movie. Explain why you chose this particular romance” to help students tie this piece together with some of the literary

Surface Area & Volume of Oblique Prisms: Student Investigation
In this investigation, students will use raw spaghetti and mini marshmallows to discover how the surface area and volume of a prism relate to the surface area and volume of the respective oblique prism. Students will be asked to create a rectangular prism using marshmallows to connect the vertices. Using a ruler, they will measure the dimensions of the prism, calculate and record the surface area and volume. Then they will make their prism into an OBLIQUE prism by giving it a slight push to t

Highly Effective Strategy for Teaching Right Triangles - FREEBIE!
Give students a transparent tool to help them label triangles!
Students often have trouble labeling parts (such as x, 2x, a, b, c, opposite, adjacent, hypotenuse, etc) of triangles for Special Triangles, Pythagorean Theorem, and Trigonometry. To help my students do this correctly, I give each student a labeled triangle printed on transparency film.
Then when students are working on one of these types of problems, they line up their transparency with the problem on their paper. They line up
