Transformation of the Absolute Value Function –

This lesson plan incorporates targeted strategies to ensure success for teachers and students. This plan can be used as a standalone lesson or as part 2 of an Absolute Value unit. Part 1 can be found here: https://www.teacherspayteachers.com/Product/Introduction-to-Absolute-Value-Functions-Lesson-Plan-3744218

Strategies Include –

A ‘Do Now’ to assess student fluency, activate prior knowledge and focus student minds on math.
The use of technology (Desmos Graphing Calculator) to enable student exploration, observation and analysis of core concepts.
Practice to demonstrate learning.
And an ‘Exit Ticket’ which provides the teacher with valuable data regarding student understanding and readiness to progress.

Lesson Plan –

Students will complete a ‘Do Now’ to assess their prior knowledge of graphing the absolute value function with a horizontal shift. Students then use Desmos Graphing Calculator to complete a 3-part activity exploring the impact of a, h and k transformations on the parent function. This is followed by written summarization of overall observations and practice graphing f(x) = a|x-h|+k. The lesson ends with a final ‘Exit Ticket’ that checks for student understanding and facilitates teacher planning.

Calculate and interpret the average rate of change of a function (presented symbolically or as a table) over a specified interval. Estimate the rate of change from a graph.
For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship.
