In this activity, students learn to use the substitution method. Step by step instructions guide students in using graphing calculators to input a system of linear equations and then solve with substitution. Teacher notes and practice problems aid in teaching the concept.MathematicsAlgebra2015-10-18T20:55:10.082793Course Related MaterialsPlanet Hop

A statistics lesson on describing and making claims from data representations, specifically linearly increasing data. Applies ideas of rate-of-change to develop writing a linear equation to fit the data, using the equation to interpolate and extrapolate additional information, and integrating the mathematical interpretation appropriately into a social sciences argument.Sarah AhmedJohanna LangillMathematics and Statistics2015-07-31T02:51:49.388819authored materials
