Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

A team of scientists periodically measures and records to volume of sea ice in the Arctic Ocean. The scientists use the sequence shown to report the volume of ice, in cubic kilometers, every 5 years from 1980 to 2015, where represents the volume of ice in 1980 and represents the volume of ice in 1985.

Students are asked to find the first five terms of a sequence defined recursively, explain why the sequence is a function, and describe its domain
Students are asked to determine if each of two sequences is a function and to describe its domain, if it is a function.
This learning video introduces students to the world of Fractal Geometry through the use of difference equations. As a prerequisite to this lesson, students would need two years of high school algebra (comfort with single variable equations) and motivation to learn basic complex arithmetic. Ms. Zager has included a complete introductory tutorial on complex arithmetic with homework assignments downloadable here. Also downloadable are some supplemental challenge problems. Time required to complete the core lesson is approximately one hour, and materials needed include a blackboard/whiteboard as well as space for students to work in small groups. During the in-class portions of this interactive lesson, students will brainstorm on the outcome of the chaos game and practice calculating trajectories of difference equations.
