There’s a wealth of information hidden where two equations have the same solutions, and graphing and seeing where two curves intersect can guide us there faster.
In this lesson, students write, solve, and graph systems of linear equations to determine how long it takes to pay off a ticket and debate the fairest ways for cities to raise revenues without harming their poorest residents.
In this lesson, students write linear equations to model the homeless populations in New York City and Los Angeles and discuss what they can do to aid people experiencing homelessness in their communities.
Students write and solve linear equations to determine how long it would take to donate a wig’s worth of hair and discuss ways they can support peers with conditions like Leukemia and alopecia.
In this lesson, students write and solve linear equations to estimate when Arlington National Cemetery will reach capacity, evaluate various proposals to prolong its lifespan, and debate the best way for Arlington to honor soldiers and their families.
In this lesson, students write and solve systems of linear equations to determine how long it would take to pay off various degrees and discuss the pros and cons of different educational paths.
In this lesson, students use systems of linear equations to explore the relationship between wage and labor, analyze the economics of fast-food restaurants, and debate whether the federal government should increase the minimum wage.
This activity allows students to explore ways to be creative by designing and making a pieces of art with polar graphs.
