To Be Linear or Not to be Linear, That is the Question

Build a square physically, with representations, and, finally, algebraically. The lesson plan takes the class through the concept of completing the square first concretely, secondly by using representations, and finally via abstract...

There's just something special about lines in algebra. Introduce your classes to linear equations by analyzing the linear relationship. Young mathematicians use input/output pairs to determine the slope and the slope-intercept formula to...

What do forest fires have to do with math? Learners use their knowledge of linear and exponential functions to explore a real-world scenario involving a forest fire. The lesson employs group work and discussion to assist learners as they...

Not all linear functions are linear transformations — show your class the difference. The first lesson plan in a unit on linear transformations and complex numbers that spans 32 segments introduces the concept of linear transformations...

Playing with matches (unlit, of course) becomes an engaging learning experience in this fun instructional unit. Teach pupils how to apply properties of exponential functions to solve problems. They differentiate between quadratic and...

What does it mean for two vectors to be linearly independent? The resource presents the basics of basis vectors and linear combinations. The third video in the 15-part series provides a definition of linear independence in terms of the...

Just let the technology do it. Pupils develop a spreadsheet to graph linear equations. By creating an input/output table, learners are able to create a scatter plot and connect the points to graph a line. Scholars use textbook equations...

Connect a linear system to a linear model and watch how the system is solved step-by-step. The equation and visual representations are solved next to each other to see how each step relates to the equation and model. This is a great way...

Step up to the challenge of finding the slope of stairs. Groups measure the rise and run of a set of stairs. They share their data with the rest of the class to determine a class average for the slope of the stairs.

Ah, the dreaded systems of equations word problem. Probably one of the best ways to connect algebra to the real-world, here is a video that goes through the steps on how to detect key words and create two equations that model the scenario.
