The following blog reflects a big departure from how I have done things in the past! Maybe old dogs can learn new tricks. After going through the readings for class, I was compelled\u00a0to look at how I go about teaching. The Foxtrot cartoon below the web really struck a chord. So these lessons start with word problems. Those are usually left for the end, and students dread\u00a0them. I figure by making them part of the discovery problem, maybe the connection between the math and its applications might be easier to see. If it demystifies word problems and helps the students to understand their value, that’s even better. Every topic in the entire chapter utilizes word problems, so it can be extended to the entire chapter, not just this snippet of it. The other thing I decided was to stress simplifying. In fact, the original draft of the unit web below had “Simplifying<\/em> Systems of Equations” at it’s center. Isn’t that how we achieve the\u00a0initial goal of\u00a0\u00a0“turning two equations with two variables into one equation with one variable”? Isn’t solving for a variable just simplifying an equation by isolating the variable? Until we get to 3 x 3 equations and introduce matrix solutions, every other process we utilize in this chapter is already firmly in their tool box, they just need to use them a bit differently…<\/p>\n

Applying CBCI to Chapter on Systems of Equations\u00a0<\/strong><\/em><\/p>\n

The overall unit on Systems of equations has 6 sections and is mapped out at 13-14 days. We break it into 3 smaller units. The first, the one described in this post, covers two equations in two variables and should be about 5 to 6 days.\u00a0 A section on Linear Programming comes next and is then followed by 3 x 3 systems. Below is a web of the first unit using the first 4 steps from the text. The CBCI components for the two proposed lesson plans to accompany this unit, generalizations, guiding questions, critical content, and key skills, are spelled out in the lesson plans themselves. The web was provided as an overall look at the section.<\/p>\n
