Students will present their findings to the class.
2. In groups, students will graph population growth and predict future trends using exponential functions (Ormond 2010). A data set is available at: http://serc.carleton.edu/files/quantskills/events/NAGT02/quantskillsworldpop.pdf. Students will discuss the political and environmental implications of their findings.
3. Students will perform an exercise using exponential functions graphing increases in atmospheric CO2 concentrations (Ormond 2010). A data set is available at: http://serc.carleton.edu/files/quantskills/events/NAGT02/co2moe2edit.pdf
Students will discuss the political and environmental implications of their findings.
Standard 3:
4. Students will be divided into groups, given problems of quadratic inequalities and race to see what group can come up with the correct solutions the fastest.
5. Students will be asked to periodically write and graph homework problems on the board to teach graphing to the rest of the class.
6. Students will be given examples of graphs or tables of values of functions and asked to identify what type of function they are, based upon the appearance (Mathematics benchmarks, 2010, UT Dana Center).
