Best Practices of Technology Integration
Learners participate in a lesson in order to practice using systems of equations in order to graph them. A cumulative project in the form of a brochure, web page, or interactive kiosk make this lesson more engaging.
Curated OER
The Elimination Method
Tenth graders investigate the Elimination Method in the solving of equations. They solve the equation using this method in examples with the teacher and then transfer the new knowledge to independent practice.
Curated OER
Linear Inequalities
Ninth graders practice recognizing similarities and differences found in the graphing of inequalities and equations. Once observatioons are made they solve some of their own applying prior knowledge.
Curated OER
Musical Addition
Students place objects on their storyboards to show the equations that they are given. They draw and color objects to show the equations. Students listen to and sing addition songs.
Curated OER
Beanies
Fifth graders explore ratio problems. They study how to solve ratio problems using simple algebraic equations. Students use equations to represent practical situations and solve equations.
Curated OER
Parabola
Young scholars develop a definition of parabola and explain the relationship between the properties of the graph of a parabola and its equation. They explain how the equation of a parabola can be written in different forms and solve...

Four 4's
Students use the numbers 24 and 44 as well as four more fours to create a series of equations. Each equation should equal a number from 1-20. They work to find an equation for each number.
Curated OER
Follow That Graph
Students investigate the graphs of six trigonometric functions. They discover how changes in the equation of the basic function affect the graph of the function.

High School Mathematics Problems from Alaska: Firewood Problem
High schoolers write and solve equations for the cost of firewood by the cord, then use this information to develop tables of values and graph their equations.
Curated OER
Wacky Water World
Eighth graders calculate a system of equations to find the best ticket price for a ticket at a water park. They explain how the equations helped them make their decision on the best price.
