This task explores the real world topic of building light rails. Throughout the implementation of this task the students will learn about the cost of building railways and how to implement them within a budget. This task explores such mathematical concepts of using coordinates to find the distance between points, using coordinates to build polygons and find the area and length of sides, and writing equations of parallel lines.

The purpose of this task is to solidify and extend the idea that geometric sequences have

a constant ratio between consecutive terms to include sequences that are decreasing (0 < r < 1).

The common ratio in one geometric sequence is a whole number and in the other sequence it is a

percent. This task contains an opportunity to compare the growth of arithmetic and geometric

sequences. This task also provides practice in writing and using formulas for arithmetic sequences.

This lesson unit is intended to help teachers assess how well students are able to interpret exponential and linear functions and in particular to identify and help students who have the following difficulties: translating between descriptive, algebraic and tabular data, and graphical representation of the functions; recognizing how, and why, a quantity changes per unit intervale; and to achieve these goals students work on simple and compound interest problems.

This task is to solidify understanding that geometric sequences have a constant ratio

between consecutive terms. The task is designed to generate tables, graphs, and both recursive and

explicit formulas. The focus of the task should be to identify how the constant ratio shows up in

each of the representations.

The purpose of the task is to build fluency with the procedural work of linear and exponential functions. This task is designed to help students recognize the information given in a problem and use it efficiently. In the task, students will work with both linear and exponential functions given in tables, graphs, equations, and story contexts. They will construct various representations, with an emphasis on writing equations using various forms and using equations to graph the functions.

The purpose of this task is to compare the rates of growth of an exponential and a linear function.

The task provides an opportunity to look at the growth of an exponential and a linear function for

large values of x, showing that increasing exponential functions become much larger as x increases.

This task is a good opportunity to model functions using technological tools and to discuss how to

set appropriate viewing windows for functions. The task also leads to a discussion of whether this

particular situation should be modeled using discrete or continuous functions.

This is the first task of two that focus on understanding and using various notations for linear

functions. The task involves students in thinking about a context where students have selected the

index in two different ways, thus getting two different, but equivalent equations. The idea is

extended so that students can see the relationship expressed in point/slope form of the equation of

the line.

Students are given 4-5 coordinate points, that will represent the sheep. First, they are tasked with creating a fence around the sheep. The students will use the endpoints of each piece of fence to compute the slope, y-intercept, domain and equation of the line. They will then code the rover to draw their lines. Finally, the students can calculate the area/perimeter of their fence and calculate the cost to build the fence. The students will then be challenged to minimize the area, perimeter and cost of building their corral, recalculate the equations of their lines, stating their new slope, y-intercept, and domain.

Students are given 5 random coordinate points and must create a path of linear equations to navigate the rover around each point. Teachers can have students calculate the slope, y-intercept, domain and range of the lines. Students will calculate the distance of each line and find the total distance the rover travelled. Students will then be challenged to minimize the distance the rover travelled. Teachers can extend this to include angles and distance, where the students calculate the angle the rover should turn and then the distance it should drive to go around each point.
