This page contains a collection of digital task sequences developed using Desmos Classroom (now Amplify Classroom). They were designed for the Algebra and Trigonometry course, aiming not only to deepen mathematical content knowledge but also to strengthen quantitative reasoning and covariational thinking. Still, these digital task sequences can also be used with high school students when studying relevant mathematical topics.
Graphs and Equations
Time to Build Skyscrapers!
This activity guides students to construct the graph of a relation through the problem of building two skyscrapers.
Communicating a Relation
Through this learning activity, students explore how to communicate two quantities that change together.
Functions
A Special Day for a Special Relation
In this series of learning activities, students will (a) become familiar with functions and identify the domain, range, and codomain; (b) identify the characteristics of one-to-one functions; and (c) determine the inverse of a function.
Investigating Water Evaporation
After completing this series of learning activities, students are expected to be able to solve problems using function composition.
Down-To-Earth Mathematics: How Hot Is Our Earth?
In this series of learning activities, students develop an understanding of function transformations by investigating an important contemporary issue: global warming.
Polynomial and Rational Functions
Difference of Differences: The Same?
The main idea of a quadratic function is that the difference of the differences is constant when the input changes by one unit. In this activity, students explore this concept using the context of uniformly accelerated linear motion.
Exponential and Logarithmic Functions
Which Savings Plan Would You Choose?
Students explore how money grows in simple and compound interest schemes using linear and exponential functions.
Trigonometric Functions
Trigonometric Function Graphs: Getting to Know and Diving Deeper
Through this learning activity, students use quantitative and covariational reasoning to sketch trigonometric function graphs. They then apply their understanding of these graphs to perform transformations.
