From Rates to Algebra

From Rates to Algebra

The “From Rates to Algebra” program is all about rates, a common measure in diverse settings. Working with rates is an important element of the PSAT/SAT Math test which includes multi-step applications that also use ratios, percentages, and proportional reasoning to solve problems in science, social science, and other real-life situations.

“From Rates to Algebra” contains nine scenarios with three more to come. Students calculate and apply rates to solve problems, make decisions and model situations mathematically providing many opportunities for students to practice these skills. The scenarios include stepping-stones to algebra where students transition from rates to writing expressions involving a variable, to solving simple algebraic equations. Each scenario requires the habits of mind supported in the mathematical practices: persevering, constructing viable arguments, reasoning abstractly and quantitatively, and modeling with mathematics.

The complete book, “From Rates to Algebra,” will be available in 2022.
