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...

What does it mean to be financially responsible? Pupils begin to develop the building blocks of strong financial decision making by reviewing how their past purchases are examples of cost comparing, cost-benefit analysis, and budgeting.

Making the transition from two-dimensional shapes to three-dimensional solids can be difficult for many geometry students. This comprehensive Common Core lesson starts with writing and graphing linear equations to define a bounded region...

This thirteen-page PowerPoint presentation guides geometry learners in interpreting linear functions, linear data and their trend lines, the consequences of their constant rate of change, and growth rate. Real-life models including...

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...

To complete homework or not to complete homework ... that is the question. Decide whether it makes a difference on finals by doing homework. Individuals create a scatter plot and find a line of best fit for data on the percent of...

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.

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...

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...

Linear equations are all about form. The fifth part in a unit of nine works with the different equivalent forms of linear equations. Class members become familiar with each form by identifying key aspects, graphing, and converting from...
