Topple misunderstandings of geometric sequences. Using a context of creating ever-increasing sizes of dominoes, pupils develop a geometric sequence. The scenario provides the size of the first domino and the common ratio between...

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...

For this grade 4 language worksheet, 4th graders answer a set of 20 "basic" multiple choice questions. Answers may be submitted and checked on-line.

A famous fossil of fighting dinosaurs holds as many questions as answers. Scholars first analyze the fossil itself by virtually highlighting the specific bones of the dinosaurs and read about their function and importance. They then test...

What is DNA metabarcoding? Show your biology class the latest method for studying biodiversity in an ecosystem with a fun, informative interactive. Individuals examine the animal species that compete for vegetation, then learn how their...

You first! An interactive sets up a game between two friends who hope they don't find a lemon hidden under a tray. Pupils determine whether there is an advantage of going first. Individuals find the probabilities of each friend finding...

Understand what it takes to control planes safely. The first lesson in a series of six introduces the class to the air traffic control situation. The pupils develop their understanding of units used in air travel, then learn how to read...

In this exploring slope learning exercise, students solve and complete 4 different problems. First, they compare an object's weight on Earth to an object's weight on another planet using the information given. Then, students compare this...

Fire in the hole! Thrill your classes as they see what it's like to fire a cannon ball. Scholars practice aiming a cannon ball by altering first the firing angle, then the velocity, and finally both simultaneously. Can they discover the...

Build a pyramid of sums. An interactive presents the first five rows of Pascal's Triangle as a pyramid. Pupils match missing entries in the pyramid and continue the pattern to determine entries of other rows. The learners use the entries...

The car is behind door one — no wait, it is behind door three. An interactive allows learners to visualize the Monty Hall problem. Pupils work through the probabilities of choosing the car with their first pick. Next, they determine...

The 1590s saw the invention of the first compound microscope. Scholars learn about how microscopes work and how to properly focus one. The lesson stresses the science fields that use microscopes and the difference between electron...

Add a winning resource to your library. A self-paced interactive has users create a sample space for all possibilities of arranging first- and second-place winners on a podium. The results lead to the realization that permutations...

Connect 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...

The camera flash works based on a simple circuit, but why does it require a capacitor? Scholars work through two levels of simulations related to circuits and capacitors. The pupils first use a simple circuit with a battery,...

I scream, you scream, we all scream for ice cream bar graphs. Pupils create a multiple bar chart to represent the sales of ice cream products during the first week of summer. Using the chart, learners find the day that each of the...

Which gender spends more time playing video games? Your classes use provided data to answer this question. They first build a two-sided stem-and-leaf plot and then use the display to look for patterns. Guiding questions help them...

 A good lesson doesn't just grow on trees! Help your classes understand the concept of a stem-and-leaf plot using an interactive lesson. Learners first create a stem-and-leaf plot from a set of data by dragging the values to the...

Does the accuracy of the first guess make a difference down the line? Learners investigate the effects of the iterative process of finding roots, using Newton's Method. By moving the initial guess of a root on a graph, pupils observe the...

Work through a sequence in discovering number patterns. Using the interactive, pupils explore arithmetic and geometric sequences by setting the initial value and the common difference or ratio. Learners distinguish between the two types...

Have some fun building squares out of triangles. Pupils investigate the partial sums of odd numbers. Using the sum of the first four odd numbers, learners see that it can be rewritten as a sum containing a triangular number. Simplifying...

Geometric series either get bigger or approach a single number. So, how do you know which it is? An interactive presents three different geometric series with varying common ratios. With the aid of patterns, pupils determine values of r...

Log the values of the derivative of a logarithm. The interactive plots the derivative of the natural logarithm. Learners first determine the derivative of natural logarithm and the general logarithm. Using the formulas for the...
