What's the rule that makes it true?  A virtual function machine generates output values as learners submit the input values. Their job is to analyze the inputs and outputs for a pattern and write a function rule.

Keep it on the chains. Pupils work through the steps in the chain rule using the interactive as a guide. Learners identify the two composed functions and their associated derivatives from a set of choices. They continue on to build the...

Use matrices to solve systems of equations. The interactive introduces Cramer's Rule, using determinants of matrices to solve systems of equations. Color coding helps pupils place entries correctly from the system.

This is the ticket to learning about function rules! Using online manipulatives, scholars build a table of values and then answer questions about the related function. They examine the relationship between the input and output values and...

How does changing a graph affect the function? Learners watch the changing input-output table as they adjust the location of the line graph. Questions prompt them to complete a table of values and determine the function rule.

Challenge your classes to find the pattern of a double function machine. After recording the outputs of both machines, learners identify the pattern and the corresponding function. Both patterns involve adding/subtracting a constant.

Learn to gain power in finding derivatives. The resource introduces the power rule. Using the sliders in the interactive, pupils create polynomial functions and find their derivatives. Given the derivative of a polynomial, learners...

Examine the relationship between the input and output variables in a table of values. As learners build an input-output table using online manipulatives, they begin to identify patterns. They answer questions about these patterns...

Make the abstract a bit more concrete with an interactive that asks learners to slide an input value through a function to determine the output. Changing the slope and y-intercept allows them to see the how the output values change.

Why should classes care about the First Amendment? An engaging lesson serves as a powerful tool for answering just that. As all four cases in the lesson relate directly to freedom of expression in schools, young scholars explore the...

Watch as a function machine converts an input to an output. Learners determine the work applied by the function machine to write a function rule. Questions accompany the function machine animation to guide individuals to conclusions.

Hats off to those learning about the graphs of functions. Individuals use an interactive to plot points representing profits for a hat business. They identify a quadratic equation to represent this function and answer challenge questions...

Almost every American is familiar with the Supreme Court case of Brown vs. Board of Education. Far fewer understand the constitutional reasoning or the wide-ranging consequences of the ruling in the field of criminology. The interesting...

Pupils determine the probability of one mayoral candidate winning given the other's chance. The interactive provides a circle graph to help visualize each candidate's percentages of winning.

The sum of the parts is greater than the whole. An interactive uses a Venn-like model to show the percentage of females from a survey that have a blue dress, a red dress, or both. The pupils determine the numbers in each category...

Profit 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...

Double the fun of studying Shakespeare with an interactive that introduces English learners to Macbeth. After watching a short, animated video that presents key elements of the plot, class members complete a worksheet identifying the...

Eight questions challenge scholars to use mental math while multiplying whole numbers by powers of 10. A tool with bouncing decimals demonstrates how and where the decimal moves. Question types include several multiple-choice, a...

Americans love to learn about their rights, especially those that protect them from the government's power to invade their privacy. Young people are especially engaged by this topic. An informative lesson explores four Supreme Court...

Prime or composite, that is the question. Teach your class how to find the answer with this step-by-step presentation that defines and provides examples of each type of number. When addressing larger numbers, divisibility rules are...

Teach your class how to form the imperfect subjunctive. Included here is information on and examples of regular imperfect subjunctive verbs, irregular imperfect subjunctive verbs, and imperfect subjunctive -se endings displayed in long...

What do you do to change arrival times of airplanes when a different route is not available? The fifth interactive in a series of six presents problems where pupils must find solutions to conflicts of safety rules. They must decide how...

Eliminate a color by dragging shapes. The interactive provides a graphical color display that allows for pupils to solve a linear system by elimination. Learners combine figures following set rules for positive and negative shapes. The...

Systematically combine shapes to arrive at one solution. The resource models a system of linear equations using colored shapes. Pupils follow rules to combine circles and squares to add the two equations together, resulting in one...
