Learners perform translation and reflection. They identify the coordinate points of the new graph and create a formula for the movement. They identify the pre-image the and after image.

Have your class explore the concept of reflections as they use Cabri Jr. to construct a triangle and reflect it over a line. Learners reflect shapes across the coordinate plane and across the lines y = x and y = -x.

Eleventh graders explore quadratic equations.  In this Algebra II lesson, 11th graders use Geometer’s Sketchpad to explore the properties of quadratics and the connections with polynomials and linear equations.  The lesson is...

Students explore the different properties of conics. In this algebra lesson, students calculate the midpoint of a line, the distances between two points as they get ready to find the focus and directrix in eclipse and other conics. They...

Students use the slope and y-intercept to graph lines. In this algebra lesson, students graph linear equations and apply it to solving real life problems.

Students investigate slopes as they study topographic maps. For this algebra lesson, students discuss and apply the concept of slopes to graphing and analyzing data.

Pupils graph polynomial functions and analyze the graphs. They identify the inverse of the functions and find the domain and range. Learners will then label the functions as one to one and use the horizontal and vertical line test to...

Students pretend they have visited a forest research station on an overnight field trip. They study forest fires, use compass directions, read maps, interpret imagery, and think about the impact of fire on ecosystems.

Students operate a GPS unit to investigate the direction of glacier movement. They describe the motion of glacier movement by interpreting a graph. Students explain how scientists use glacier striations to determine glacier movement.

In this algebra worksheet, students graph exponential equations and use the formula to translate the graph on a coordinate plane. There are 3 word problems.

Learners define the term species, and graph species data together with previously collected data at the National Zoo. They interpret graphed data and recognize patterns in the streamside quadrant versus hillside quadrant. Students use...

Eighth graders investigate slopes using real life scenario. In this algebra lesson, 8th graders model and interpret real life data. They plot their data in a coordinate plane and discuss the results with the class.
