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. Teacher introduce slope-intercept form of linear equations on board, explaining the identity of the slope and the intercept. Followed by graphic demonstrations on the board of both attributes.
