Curated OER
Impossible Graphs
Students distinguish between possible and impossible graphs of functions, and to learn why some graphs are impossible. They have practiced plotting functions on the Cartesian coordinate plane
Curated OER
Calculating & Graphing Using a Spreadsheet
Students use the lab apparatus to calculate the average velocity and average acceleration at several points and record the data. They use the spreadsheets to plot distance vs. time, velocity vs. time and acceleration vs. time graphs.
Curated OER
Geometry and Symmetry
Students examine tessellations and their geometric properties. The lesson and discussions may be used to develop students' understanding of polygons and symmetry as well as their ability to analyze patterns.
