Present the world to me! Participants develop presentations about functions they learned through research. They then share their ideas about how functions apply to global warming with the class.

Practice makes perfect! Presenters practice their function presentation before a partner or small group for evaluation before presenting their project to the whole class. Pupils can then incorporate ideas from peer review into the...

This comprehensive unit on linear and exponential functions provides numerous clearly-written worksheets. Topics include graphing linear equations, solving systems of equations algebraically and by graphing, identifying the domain and...

Learners will explore linear functions. They start by comparing linear functions representing two trains racing toward each other. Next, they solve related word problems and complete corresponding data tables, graphs, and worksheets....

Paper folding, flu spreading in a school, bacteria growth, and continuously compounded interest all provide excellent models to study exponential functions. This is a comprehensive resource that looks at many different aspects of these...

New ReviewGrow to review exponential functions. With the unit review, learners identity the type of function for given equations, such as exponential growth, decay, or linear. Pupils write the correct function for situations and then use the given...

New ReviewLinear or exponential?. Learners watch an informative video comparing situations that may be modeled by either a linear or exponential relationship. Pupils determine the type of relationship and then create a function that models the...

Make up a story about a linear graph. Scholars identify key features of a linear graph, such as intercepts, domain and range, and slope. They then create a word problem that could be represented by the graphed line.

What will that cost in the future? The scenario provides pupils with a growth as a Consumer Price Index. Learners create functions for a given item to determine future prices and graph them. Class members then compare their functions to...

Sequences are all about recognizing patterns. A module of 11 lessons builds pupils' understanding of sequences through pattern analysis. The practice connects the analysis to linear and exponential equations. This is the first module in...

Functions help make the world make more sense. Individuals model real-world situations with functions. They match a variety of contexts to different function types to finish a helpful resource.

How fast does it fall? Learners use a spark timer to time and record the vertical fall of an object. They create graphs and analyze data to calculate the velocity and acceleration of the object to better understand the concept.

Drive the value of a car down. A lesson introduces the class to the idea of depreciation using car values. Pupils find a car they would like to own and determine its future value based on two depreciation rates. They graph the values...

Move linearly from specific proofs to general proofs. Pupils use two proofs to show that linear functions grow by equal differences over equal intervals. The first proof uses a specific linear function and intervals. Using the process of...

So, it's exponentially equal? Pupils show that a specific exponential function grows by an equal factor over equal intervals. They show that the ratios of the functions are the same over the same size intervals of inputs. Using the...

Is it an equal difference or an equal factor? Given four real-world scenarios, pupils decide whether they can model the relationship using a linear or an exponential function. The scholars provide an explanation of their choices.

Even if your name isn't Mary, we'll still ask you, "How does your garden grow?" Given verbal and tabular information about the number of seeds planted in two gardens, future gardeners and mathematicians determine whether or not the...

Designs from lines are sublime. Scholars create colorful designs by connecting points on an interactive coordinate plane. They answer questions about slope and quadrants based on their designs.

Bacteria can be harmful to your health, but it's great for math. Aspiring mathematicians determine the growth rate of bacteria for data given in a table. They then compare this growth rate to bacteria described verbally.

Take steps into sequences. An 11-lesson unit builds upon pupils' previous understanding of writing expressions to develop the idea of sequences. The resource explores both arithmetic and geometric sequences using recursive and explicit...
