16 pages. This mini-unit (3 days) introduces the y=mx+b form as a general formula for linear functions. From this form, students learn to write equations for linear functions given:
* Slope and y-intercept
* Slope and a point on the line
* Two points on a line
It is designed for introductory algebra students who already have familiarity with:the definition of a function (but not necessarily function notation), coordinate graphing, identifying slope of a linear function from a graph and from two points, and identifying intercepts of a coordinate graph. For me, this was Chapter 5 in our Algebra 1 textbook.
Running through the veins of this tough content is the essential question: "How do patterns help solve problems?" I think it is important that the students ponder the significance of recognizing patterns, and using generalized language to express them. It is through this ability to generalize patterns as they see them that we empower our young algebra students.
This complete mini-unit includes an introductory lesson, an exploration activity, a practice set, and a quiz. The unit is aligned with the common core standards and also includes essential questions, objectives, teacher notes and full answer keys. You should allow about 3 days for this unit (2 days in a block schedule).
The FREE preview option includes the full lessons for your perusal (minus the answer keys). Feel free to take a free look before you purchase.
