ResourceSpotlight
Students first solve linear absolute value equations in a single variable using the definition of absolute value to write and solve two equations. They then explore the handheld's functionalities for solving and checking such equations. Students view graphs of absolute value inequalities, compare them to those of compound inequalities, and practice writing absolute value inequalities as compound inequalities. They solve absolute value inequalities and check their solutions by graphing them.

In this activity, students will learn to identify the domain and range of various real-world step functions. They will graphically explore numerical data points and observe step functions. Open and closed points on a graph are investigated and discussed. Students use self-check questions to check their understandings with immediate feedback. Extension questions are also provided to apply what is learned to determine the domain and range of other functions.

In this activity, students will investigate inequalities. Applications of inequalities to volume and perimeter provide motivation to develop a deeper understanding of the topic. Dynamic sliders and self-check questions make this activity approachable for Algebra 1 students. Students can put into practice what they have learned with extension/homework questions.
