Slide into a lesson on proportions. A slider interactive lets users adjust three of the four values in a proportion and automatically updates the fourth value. Scholars use the interactive to help answer a set of challenge questions on...

Discover the pattern of exponents through an interactive lesson. Young mathematicians manipulate sliders and watch the result as they change the base or exponents in an expression. The tutorial shows them the simplified expression and...

Zip this resource into your lesson plans. Here is an interactive that shows how angles and lengths change based on conditions for a zip line. Scholars use the Law of Cosines to solve problems in this context.

Drink in this resource. Young problem solvers investigate a different way of looking at the problem of filling four liters of water from a three-liter cylinder and a five-liter cylinder. Isometric grids help with this understanding.

Here's an interactive that complements your lesson plans. Users of the resource adjust one of the angles in a complementary set to see how it affects the other. A set of challenge questions assesses understanding.

Don't freeze out the interactive on inequalities from your lesson plans. Young mathematicians use an interactive thermometer and number line to compare freezing temperatures. Inequalities help express these comparisons.

Inject a great interactive into your lesson plans. Scholars learn about injections, surjections, and bijections of sets. They use an interactive that shows an example for each of these relationships between sets.

Here's an interactive that will be a great match for math lesson plans. Young mathematicians use an interactive game to match fractions represented numerically and as fraction models. One game assesses fractions only, while the other...

Learn about functions using the function builder app. A fun online interactive has the class conduct an investigation using a function machine. Inputs are pieces of art, and output are transformations of these pieces of art.

Who Am I? Scholars go online to gather clues and evidence to uncover just who was involved in the American Civil War. They use hands-on Internet activities to come to an understanding of the roles soldiers and civilians played in the...

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.

Explore constructions through an interactive online lesson. Given an example of an angle bisector construction, learners investigate the markings to determine the method used. Challenge questions help solidify the steps. 

Learners, through watching a simulation, can manipulate various characteristics of different solutions focusing on acid-base solutions where pH, strength of solution, and concentration may be changed. Views may be at the molecular...

Apply the concepts of conservation of energy to a skater to introduce a fun way the concepts apply to real life. Scholars build tracks, ramps, and jumps then analyze the various types of energy and friction. For an added challenge,...

Have you ever stretched out a Slinkie so much it wouldn't go back to its original shape? Slinkies, like all springs, follow Hooke's Law. A simulation uses springs and masses to demonstrate kinetic, potential, and thermal energy. It...
