This task requires students to use functions to calculate how to best benefit from a pizza promotion.

This task is designed to get at a common student confusion between the independent and dependent variables. This confusion often arises in situations like (b), where students are asked to solve an equation involving a function, and confuse that operation with evaluating the function.

This electronic activity uses Desmos to walk students through graphical representations of polynomial transformations. Students work at their own pace or through teacher controlled pacing to explore cases and illustrate an explanation of the effects on the graph using technology.  Teachers can also select and highlight student responses and bring them to the attention of the entire class. Link to Activity

In this task students construct and compare linear and exponential functions and find where the two functions intersect. One purpose of this task is to demonstrate that exponential functions grow faster than linear functions even if the linear function has a higher initial value and even if we increase the slope of the line. This task could be used as an introduction to this idea.

Students follow the steps of the engineering design process while learning more about assistive devices and biomedical engineering applied to basic structural engineering concepts. Their engineering challenge is to design, build and test small-scale portable wheelchair ramp prototypes for fictional clients. They identify suitable materials and demonstrate two methods of representing design solutions (scale drawings and simple models or classroom prototypes). Students test the ramp prototypes using a weighted bucket; successful prototypes meet all the student-generated design requirements, including support of a predetermined weight.

This course will cover families of functions, their properties, graphs and applications. These functions include: polynomial, rational, exponential, logarithmic functions and combinations of these. We will solve related equations and inequalities and conduct data analysis, introductory mathematical modeling and develop competency with a graphing calculator.Login: guest_oclPassword: ocl

In this task students are asked to analyze a function and its inverse when the function is given as a table of values. In addition to finding values of the inverse function from the table, they also have to explain why the given function is invertible.

This task requires interpreting a function in a non-standard context. While the domain and range of this function are both numbers, the way in which the function is determined is not via a formula but by a (pre-determined) sequence of coin flips. In addition, the task provides an opportunity to compute some probabilities in a discrete situation.

The task is better suited for instruction than for assessment as it provides students with a non standard setting in which to interpret the meaning of functions. Students should carry out the process of flipping a coin and modeling this Random Walk in order to develop a sense of the process before analyzing it mathematically.

This lesson is intended to help you assess how well students are able to:
Articulate verbally the relationships between variables arising in everyday contexts.Translate between everyday situations and sketch graphs of relationships between variables.Interpret algebraic functions in terms of the contexts in which they arise.Reflect on the domains of everyday functions and in particular whether they should be discrete or continuous.
The lesson includes a pre-assessment activity.  The lesson is designed for students to work in small groups on a collaborative task, matching situations, sketch graphs, and algebraic functions. They refine the graphs and interpret the formulas to answer questions. Students then discuss as a whole-class what has been learned and the strategies used.  Finally, a follow-up post-assessment is included and similar to the pre-assessment to use what they have learned.

Mathematical goals
This lesson unit is intended to help you assess how well students are able to understand what the different algebraic forms of a quadratic function reveal about the properties of its graphical representation. In particular, the lesson will help you identify and help students who have the following difficulties:
Understanding how the factored form of the function can identify a graph's roots.Understanding how the completed square form of the function can identify a graph's maximum or minimum point.Understanding how the standard form of the function can identify a graph's intercept.

Before the lesson, students work individually on an assessment task that is designed to reveal their current understandings and difficulties. You then review their work and create questions for students to answer in order to improve their solutions.After a whole-class interactive introduction, students work in pairs on a collaborative discussion task in which they match quadratic graphs to their algebraic representation. As they do this, they begin to link different algebraic forms of a quadratic function to particular properties of its graph.At the end of the lesson there is a whole-class discussion.In a follow-up lesson students attempt to improve their original response to the assessment task.
Materials required
Each individual student will need two copies of the Quadratic Functions assessment task and a mini-whiteboard, pen, and eraser.Each pair of students will need Domino Cards 1 and Domino Cards 2, cut into ten ‘dominoes'.
Time needed
15 minutes before the lesson, a 95-minute lesson (or two shorter lessons), and 10 minutes in a follow-up lesson. Timings are approximate and will depend on the needs of the class.

In this task students draw the graphs of two functions from verbal descriptions. Both functions describe the same situation but changing the viewpoint of the observer changes where the function has output value zero. This small twist forces the students to think carefully about the interpretation of the dependent variable.

The purpose of this task is to give students an opportunity to explore various aspects of exponential models (e.g., distinguishing between constant absolute growth and constant relative growth, solving equations using logarithms, applying compound interest formulas) in the context of a real world problem with ties to developing financial literacy skills.

In this unit of five lessons from Illuminations, learners begin with a number-line model and extend it to investigate linear relationships with the Distance, Speed, and Time Simulation from NCTM's E-Examples. Students then progress to plotting points and graphing linear functions while continually learning and reinforcing basic multiplication facts. Instructional plan, questions for the students, assessment options, extensions,and teacher reflections are given for each lesson as well as links to download all student resources.

The task provides an opportunity for students to engage in Mathematical Practice Standard 4: Model with mathematics.

The context of this task is a familiar one: a cold beverage warms once it is taken out of the refrigerator. Rather than giving the explicit function governing this warmth, a graph is presented along with the general form of the function. Students must then interpret the graph in order to understand more specific details regarding the function.

This problem is a quadratic function example. The other tasks in this set illustrate F.BF.1a in the context of linear (Kimi and Jordan), exponential (Rumors), and rational (Summer Intern) functions.

Use this spreadsheet after students have been taught the basics of spreadsheets: entering and editing data, formatting a spreadsheet, basic functions, sorting, creating and formatting charts. Students use Skittles (can also use M&Ms or another candy or type of food with different colors that can be sorted) to create a spreadsheet. They will sort the data, create functions to analyze the data, and insert a chart.
