Boost mathematicians' proficiency of binary numbers 17 to 24 with an interactive comprised of six questions—multiple-choice, true or false, and a discussion. A color-coded table reveals binary equivalents to aid in the problem-solving...

Challenge mathematicians to crack the binary code with an interactive that focuses on numbers nine to 16. A table reveals exponential equations to aid in answering multiple-choice questions. A discussion question gauges comprehension. 

A six-question interactive tasks mathematicians to solve addition and subtraction problems using front-end estimation. Question types consist of multiple-choice and true or false. A set of wooden beams that can be measured using moveable...

Think outside the box and use an engaging, interactive app that shows the relationship between square roots and squares using an actual square. Pupils find that moving a slider increases the side length of a square and its associated area.

Watch as your learners reach even loftier heights of understanding. Individuals use a slider to estimate the height of a person whose height is given in radical form. Rationalizing the denominator comes in handy here.

Shake up your lessons with with a radical resource. Scholars use a slider to view the Richter scale magnitude and amplitude of historical earthquakes. They use powers of 10 to compare the amplitudes of different earthquakes.

Learning about tangents doesn't have to be a slippery slope. Pupils drag a point around a unit circle to see how angle affects the slope of a line. They individually answer a set of challenge questions to come to the conclusion that...

Drawing triangles is easy, even if you have to calculate the exact length of its sides. Scholars use the Law of Cosines to find missing sides of triangles. An interactive helps them check their answers.

An identity that thieves can't steal  the tangent identity. Scholars manipulate ratios to investigate the tangent ratio and connect it to the sine and cosine ratios. An interactive that uses color coding helps with this task.

The more you know, the more you can learn. Scholars apply the double angle and half angle formulas to determine trig values based on known values. They use an interactive that provides sine and cosine values to aid calculations.

Slide the resource into your lesson plans. Young mathematicians use a slider to move a movie screen to the right position for optimal viewing. Along the way, they learn to apply the half angle formulas.

Don't lose your marbles. Scholars use an interactive to create a triangle that closes off a portion of a sidewalk with loose marbles. The Law of Sines helps them find the side measures of such a triangle.

Mixed numbers are the focus of a five-question interactive. Scholars move fraction pieces into strips and equations to find solutions. Questions challenge participants with multiple-choice, a true or false, and one discussion.

Five questions challenge scholars to add mixed numbers. A tool creates a visual model that separates whole numbers from fractions parts. Problem types include fill in the blank, true or false, and discussion.  

Some lessons feature videos, some interactive practice problems, and some have notes and activities. This comprehensive look at factoring and solving polynomial equations using the zero product principle has all of this and more. Though...

How do people express their rights of free expression through the press? Journalism 101 is the perfect combination of modules for 11th and 12th graders to learn about First Amendment rights, reporting and writing skills, digital...

Why do some things float and others sink? A creative simulation allows learners to adjust mass and volume of an object to affect its buoyancy in water. A graph records the effect of each manipulation.

Explore the chemistry behind the airbags that keep you safe in a collision. Using a simulation, your classes find the best gas to use to inflate an airbag. The simulation shows the time it takes to inflate to a maximum volume....

Chemistry can help athletes and others protect and treat injuries. Use the interactive activity to explore the chemical reactions in instant hot and coldpacks. Learners manipulate the type of salt in the pack and watch the reaction take...

Don't take for granted the technology behind power packs. Build an understanding of the chemical mechanics of a battery pack that charges your phone. The simulation allows young scientists to manipulate the type of elements in a pack and...

Make the microscopic world of chemical reactions come to life. An engaging video demonstrates a methane-oxygen reaction. Learners see the reaction take place and observe the chemical equation being balanced. 

Examine the chemistry of the laundry room! A thorough video explains the polarity and non-polarity properties of soap. The tutorial continues to explain the advantage of these properties in stain removal by showing the...

Gaps are essential to engineering bridges and roads. Learners watch a video showing a typical construction of a bridge to see why they're so important. They then manipulate an interactive to model the effects of temperature change on the...

Salt is the go-to material when people need to melt ice—learn the chemistry behind its effectiveness with an interactive lesson. Pupils watch a short narrative and then explore the concept through a simulation. Young scientists...
