As a mathematician, I am thankful for shortcuts. I think part of the reason that I have always loved math so much is because I recognize and implement shortcuts. I love to look for patterns in numbers and procedures. I try to share these tips and tricks with my eighth grade math students whenever I can. Here's an easier way to write linear equations in Standard Form. By Free to Discover.
I have done a project similar to this. It adds more rigor if students create their own equations and develop their own design. I usually have them create a certain number of each type of line, have them identify slope, y-intercept, etc. to cover more of what I am teaching on the concept.
Check out our flipped classroom animated math lesson on finding and using slope! This lesson is perfect for students with a visual learning preference and is aligned with the common core learning standards for Algebra I. You can access all of our video lessons at youtube.com/mashupmath!
Teaching Systems of Equations with inquiry learning. Students will be doing the thinking- drawing connections and making conclusions to help them learn about systems of equations in a deeper way. My students loved this approach!!!!
