New ReviewHow long will it take to save for a down payment? A scenario provides information about saving for a down payment for a car. Pupils use the information given to create a function to model the amount saved. They determine how much they...

New ReviewAntarctica is a big place, large enough to provide ample opportunities to learn about math. A two-week unit teaches middle school mathematics concepts using project-based learning. The resource covers functions, geometry (area,...

New ReviewThere's no match for a great graphing resource. Given the graph of a function, young mathematicians create the equation for the function by filling in the necessary coefficients. The interactive graphs the user's function to see if the...

New ReviewGraphs are useful for many things, including seeing how much money you can make. Individuals create a graph of earnings from a job based on the number of hours. They determine the domain and range of the graph and answer challenge...

New ReviewScholars model a million-dollar store giveaway with an exponential decay function. Substitution into this equation helps solve a problem related to this situation.

New ReviewHow much does it cost to add more mangos? An interactive allows users to see how the price of frozen yogurt changes based on the number of scoops and the number of slices of mango. Learners then answer a set of challenge questions about...

New ReviewTo be (a function) or not to be (a function). An easy-to-use interactive has pupils drag a vertical line onto several graphs to determine if they represent functions. Some challenge questions assess understanding of this idea.

New ReviewProfit from this interactive on graphing and interpreting functions. An interactive allows learners to plot a square root function representing a company's profits. They answer some challenge questions that require interpreting this...

New ReviewSetup the idea of functions for the class. Using sets, the presentation introduces the concept of a function. The initial example uses a general function but then moves on to equations as functions. The video provides an example of an...

New ReviewIs 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.

New ReviewFunctions are special types of relations, but what makes them so special? Pupils use an interactive to slide a vertical line across six different graphs. Ten challenge questions then assess understanding of functions.

New ReviewWhat do vertical lines have to do with functions? Individuals slide a vertical line through four different graphs. They use that vertical line test to determine if the graphs represent functions.

New ReviewConnect the dots to graph a linear function. Young mathematicians use an interactive to first plot provided points on a coordinate plane. They connect these points with a line and then answer questions about the slope and y-intercept of...

New ReviewWhat does f(a) mean in the real world? Given a distance-time graph, individuals first locate f(3) on the graph. They then interpret this value in terms of the context.

New ReviewAn assessment provides four graphs of relations. Pupils identify which of the four are functions and provide an explanation of why. They then explain the reasoning behind the vertical line test if they used it to find the functions.

New ReviewSee if the class can spot the function. A short assessment presents four relations as either x/y tables or mapping diagrams. Pupils decide whether the relation represents a function or not and provide a justification for their decisions.

New ReviewExponential Function + Constant Function = Bacteria? Pupils first write a function for the population of reproducing bacteria from given information. Combining this with a constant function, they write a function representing the total...

New ReviewExplore linear function patterns through a collaborative activity. Young scholars examine a given scenario and work to model the situation with a function. The question is intentionally left open-ended to encourage multiple solution...

New ReviewTake the principles of vectors and apply them to other things that act like vectors. The last video in the series of 15 introduces the more abstract aspects of linear algebra, making the connection back to the vector concepts discussed...

New ReviewIf you've ever wanted to start a summer business, now's your chance. Individuals research options and costs for starting a summer business. They create equations regarding start-up costs and write up a proposal for their business.

New ReviewNo need to line up for this resource — everyone can use it! Pupils write a linear function from its graph. The problems involves a line that does not have an integer value for the y-intercept.

New ReviewRepair any holes in understanding linear functions. Individuals write a function to represent a situation given verbally. The context involves costs for computer repair.

New ReviewDo taxes apply to delivery charges? Scholars create functions representing total cost of furniture after delivery fees and after taxes. They use composition to create functions for the total cost where tax is levied on delivery fees and...

New ReviewBe careful when evaluating with negatives. Young mathematicians determine the value of a function for x = -3. The function is quadratic, so they must use caution when squaring the negative input value.
