Crash Course: Study Hall Algebra #12 - Linear and Simultaneous Equations and Graphs
Crash Course

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.

Crash Course: Study Hall Algebra #13 - All Kinds of Graphs
Crash Course

In this episode of Study Hall: Algebra, we’ll tweak the techniques we’ve learned in our last two episodes on graphing — like employing symmetry and plugging in points to plot data — to graph just about everything else we might encounter in college algebra.

youcubed: Polar Graph Art (9-12)
youcubed (Stanford University)

This activity allows students to explore ways to be creative by designing and making a pieces of art with polar graphs.

youcubed: Walking the Graph
youcubed (Stanford University)

Students often find the interpretation of graphs extremely difficult – this has been shown in research and from many stories of interviews with college students and with younger students.

Khan Academy: Algebra 1
Khan Academy

The Algebra 1 course, often taught in the 9th grade, covers Linear equations, inequalities, functions, and graphs, Systems of equations and inequalities, and more.

Khan Academy: Trigonometry
Khan Academy

Learn trigonometry for free—right triangles, the unit circle, graphs, identities, and more.

Illuminations: Pizza at Home
Illuminations (National Council of Teachers of Mathematics)

Students survey members of their community to determine preferences about pizza.

Illuminations: Let's Compare
Illuminations (National Council of Teachers of Mathematics)

Students collect numerical data, generate graphs, and compare two data sets.

Illuminations: Domain Representations
Illuminations (National Council of Teachers of Mathematics)

Students use graphs, tables, number lines, verbal descriptions, and symbols to represent the domain of various functions.

Illuminations: Movie Lines
Illuminations (National Council of Teachers of Mathematics)

This lesson allows students to apply their knowledge of linear equations and graphs in an authentic situation.

NRICH: Translating Lines
NRICH (University of Cambridge)

Investigate what happens to the equation of different lines when you translate them. Try to predict what will happen. Explain your findings.

NRICH: Reflecting Lines
NRICH (University of Cambridge)

Investigate what happens to the equations of different lines when you reflect them in one of the axes. Try to predict what will happen. Explain your findings.
