The students new to this subject are to reenforce their learning in manipulating equations to obtain the slope-intercept form while the advanced students assist and at the same time review their prior learning from past years. Then students are to explain the significance of the slope and intercepts and changes to these two attributes. The period begins with board work lecture demonstration by the teacher, then group problem sheet, then demo on computer by the teacher, then a practical lab on the computer by students in groups. Students show difference between positive and negative slopes. Students explain impact of changing the slope on a graph.
Students explain impact of chaning the slope in practical applications.
Students explain the significance of the intercept on a graph. Students explain the significance of the intercept in practical applications. Students be able to identify equations to match graphs of differing slopes and intercepts using the GreenGlobs program. I students must have experience with the standard form of linear equations and the common manipulations of equations. This is a review for the Geometry and Algebra II students in preparation for extensions required in their courses.
