This optional sequence of lessons uses the context of running a restaurant to review mathematical concepts from previous units. While the lessons in this section are related to each other, they do not need to be completed in order. It is not necessary to do all of the lessons to get some benefit, although more connections are made the further...

These optional lessons do not build on each other and can be completed in any order. The lessons focus on proportional reasoning, writing algebraic expressions representing real-world situations, decomposing regions, and scale drawings. Each lesson builds on skills developed in earlier units.

All standards in this section have been addressed in prior units. This section provides an optional opportunity for...

This optional sequence of three lessons can be done any time after Unit 6 in this course. The activities in these lessons provide students a chance to go more deeply and apply grade 8 mathematics to a real-world context. Students get a chance to engage in aspects of mathematical modeling throughout this section. The activities in these lessons build on...
