Reflection of Light With Two Plane Mirrors- Double Mirrors Placed at a Number of Angles

Challenge students' understanding of area and the coordinate plane with this exit ticket exercise. Given the ordered pairs corresponding to the vertices of two triangles, young mathematicians must find the area of the quadrilateral...

Three letter-sized mini posters can be displayed in your elementary geometry class when teaching about angles. One provides information about degree measurement and additive properties, and the other two define acute, right, obtuse,...

If it's a simple set of two-digit multiplication problems you need, you've found it! There are 16 problems here, each with two double-digit factors. Learners find the products and regroup. There are examples to get them started, but none...

Illuminate your class with this fabulously interactive app about light! Brilliant animation follows a beaming little robot as he teaches youngsters about every glowing object and concept under the sun.

Discover the parallel structure of parallel lines. Provided with two parallel lines on a coordinate plane, the presenter shows that the rise and run, or slope, of the two lines are the same. The resource, which is a portion of a larger...

Viewing this Khan Academy video helps with grasping the concept of Place Value. Learners write the word six hundred forty-five million, five hundred eight-four thousand, four hundred sixty-two in standard form, using multiplication as a...

How can geometry learners remember the difference between supplementary and complementary angles? Not only will the video explain how to remember these two angles, but it also demonstrates how to find unknown angles knowing the degree of...

Where does the reflection come from? The vivdeo starts with a quick review of the form of the equation of horizontal and vertical lines and diagonals passing through the origin. Using a pre-image and an image of a reflected figure, the...

Any work with light, lenses, lasers, or mirrors is called optical engineering. Optical engineers bend and bounce light to make it useful for humans. Examples are telescopes, invisibility, nanomedicine, and solar energy. This...

Let there be light in your classroom with a video that explains that light travels in waves, the electromagnetic spectrum contains seven colors, and the color of an object depends on which light waves it reflects and absorbs. With...
