Isolating the Variable
Ninth graders investigate how to solve equations with the variable present on both sides. They practice isolating the variable and combining like terms before solving the equation for the variable.
Curated OER
Linear Functions
Fifth graders investigate the concept of a function in relationship to how it is used. The concept is essential for the future study of Algebra. They apply the use of patterns with its relationship to functions.
Curated OER
Graphing Ordered Pairs
Seventh graders investigate the concept of ordered pairs as found in Algebra. They are introduced to the data set that corresponds to the coordinate system. Also students practice the graphing the ordered pairs using the x and y axis.

Down the Drain
Students explore what problems might occur if oxygen decreases in a body of water. They model what happens in a situation where decomposition is occurring. Students obtain, organize, graph, and interpret information. They i interpret...
Curated OER
Paper Planes
In this unit, 3rd graders investigate one variable to see if they can make a paper plane fly farther. They use scatter plots to establish a possible relationship between variables then use what they have found to make a paper plane to...
Curated OER
Seed Growth
Students develop an independent procedure to investigate the germination of two types of seeds. Students must construct data tables or charts to record observations and results, graph the data, and analyze the data.
Curated OER
Use Scientific Method to Solve Problems
Learners are given a set problem, they use the scientific method to solve the problem using all steps of the scientific research. Students list the steps of the scientific method used in solving a problem. They are given a selected...
