NFS Curriculum Update :: December, 2015
Eighth graders will continue solving linear systems by graphing and learn substitution and elimination methods. We will interpret given scenarios and transform them into linear systems with two variables. Mixtures, interest, and wind/air speed are all new real-life applications that will be explored. As a class, we will explore when Netflix, Red Box, and movie rentals are most affordable. Students will also determine whether or not the NASA astronauts have enough oxygen to install solar panels on the International Space Station with regard to oxygen usage.
Right before break, the analysts will then choose between comparing cell phone plans, cable plans, or two cars to synthesize which is the better buy based on the group’s consumer’s needs and desires. The cooperative groups will construct scenarios, linear systems, and a conclusive report that will be shared with the class. The cumulative math midterm and culmination of the project will occur in mid-January.
Eighth graders have been exploring real-world connections with linear systems by reading word problems, constructing linear systems, solving for the intersection, and then summarizing what the point of intersection means. One specific application we will be investigating is determining whether or not the NASA astronauts have enough oxygen to install solar panels on the International Space Station with regard to oxygen usage. Students will also compare electricity plans to determine whether solar panels are worth the cost. Next, students will write and graph linear inequalities and systems of linear inequalities, concluding the acceptable range of solutions for the situations and explain what the range means.
Right before break, students will begin working in cooperative groups and create scenarios around a specific topic that involve a two or three-variable linear system. Within these scenarios, the groups will create and describe the scenario as a linear system, solve the system, and advise the client based on the results. The cumulative math midterm and culmination of this authentic project will be in mid-January.
