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!

Introduction to Domain and Range Activity
Domain and Range are so tough for my students to understand. The first part of this activity is a mini lesson where either the teacher or student-led groups discover how to draw boxes on the axes to help write the domain and range in interval notation. This activity has a Check for Understanding so that you can see at the end of the mini lesson how much your students have grown on this topic.

Show and explain the steps for solving an absolute value equation minilesson
This minilesson is a great way to guide students through the whys and hows for solving absolute value equations. Use the Check for Understanding at the end to get feedback from your students on what they learned.

Rewrite Formulas Activity
This standard is a really tough one to cover because it is worded so unnaturally and is found within a lot of different units. My way to cover this is in algebra 1 by using the simple example of the formula for the perimeter of a rectangle and then giving the students a couple of examples to work with that are familiar to them. Try it out!

Derive Geometric Summation Formula
This standard is very hard to cover. This activity is an attempt to use student language to help them learn how to derive a formula that is really nice to know. I would recommend that you lead them through this activity, but if your students are more advanced, let them attack it in groups.

What is a solution? Activity
I found that my students never truly understood the definition of a solution in terms of a function with regards to a table, graph, ordered pairs, and a function. This activity also includes a Check for Understanding at the end.

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.
