Slopes of Parallel and Perpendicular Lines Discovery Activity
Want to create a student-led learning environment? Give your students the opportunity to practice their graphing skills as well as their ability to come to conclusions with this activity. In this activity, students graph linear functions and use their equations to discover the relationships between the slopes of parallel and perpendicular lines ALL ON THEIR OWN!

Beginning of School Year Pretest_Activity - Algebra II/Geometry
Need something to kick off the school year? This activity is an "escape the room" that serves as a pretest so that you can gauge your algebra 2/geometry students' prior knowledge. This activity usually spans 2-3 class periods. At the end of the activity, the students get a passcode which I used to let them unlock my cell phone which has a message displayed that tells them the location of their prize.

Area of a Triangle using Sine
This standard is a tough one to cover, so I built this activity to help lead my students through it. I split up the class into groups of threes and have them work through it at a whiteboard. I roam the room and listen to their discussions and try to help only if there is no activity within the group. If you are interested in a thinking classroom, this is an easy one to try.

Slopes of Parallel and Perpendicular Lines Gallery Walk
After delivering the lesson on the relationships between the slopes of parallel and perpendicular lines, do this activity! It reinforces the main concepts by turning the boring worksheet into a game! The last slide is the answer key.

Determine the slope activity
In this activity, students must match slopes, slope between points, linear functions, and graphs of lines with each other so that they match. It is a great way for students to practice translating between all of these different representations of slope.

Geometric Constructions Gallery Walk
After my students learn how to do some of the basic constructions, I have them work through this gallery walk in pairs. They have to use a compass and straightedge and show me their results in their notebook.

Basic Geometry Definitions I have who has cards
A great way to have students interact with one another on geometric definitions. The cards print double sided, but the back side is NOT the correct definition. Instead, the student has to find the person that has their definition/term on their card. Great day 2 activity!

Slopes of Parallel and Perpendicular Lines Pretest_Posttest
Need to show growth for your admin?? How about giving your students a pretest before teaching this topic and then doing the same thing afterwards to see how much they've grown? Sounds great to me!

Geometric Constructions Independent Practice
This is the homework I assign after we do our lessons on constructions. Make sure to send the tools home with the students!! Also, don't forget to check out Euclidea (phone app). I don't work for them, but it is a great way to get your students to practice!

Experience

Teaching style
In my classroom, I take a constructivist approach allowing my students to facilitate the learning. My job is to create the activities to keep them topical and guide them along a path of success. I am a staunch practitioner of a thinking classroom where my students spend the majority of the time collaborating around the solution of a problem up at the boards around my classroom. To outsiders, if might be chaos. We just call it learning.

My own education history
I attended Southeast Missouri State University to earn a Bachelor's degree in Secondary Education - Mathematics and a Bachelor's degree in Applied Mathematics. My passion for math led me to attend grad school at Southern Illinois University Carbondale and earn my Master's in Mathematics.
I have over 80 hours of training when it comes to working with students with autism, ESOL, and high risk students.
