Quadrilateral Teacher Resources

Apply the distributive property to multiply a monomial times a polynomial to get the area of a rectangle. Then use this information to solve a word problem.

Multiply a number by itself and that is squaring a number. Simple as that, and, if it's an integer you have a perfect square.

The teacher illustrates a diagram to help you learn about perimeter. First she adds the sides together to get the perimeter. Then she shows how to use the perimeter formula to make it a bit simpler.

The teachers uses a diagram to set up her initial equation to reflect the changes being made to a garden plot. She has a good explanation of how she got her equation. Then she works through the steps to solve the equation.

The teacher explains how the formula for a triangle was determined. It is related to a parallelogram. What? The formula for the area of a triangle is derived from the area of a parallelogram? Seeing is believing, so watch this video to...

Is prism just another mathematical term for a solid? It must be since this lesson is about volume. The teacher illustrates and explains how to find the volume of a rectangular prism and also how to find the volume of a triangular prism....

I always thought a prism was a solid triangular shaped piece of glass that made rainbows when the light shined through it. Well, that is a prism, but that is only one example of a prism, as prisms are three-dimensional solids of a...

What's the definition of the power of a quotient rule? You have a fraction that has variables and exponents in the numerator and the denominator, and the whole thing is to a power. Oh my! Don't cry! You can do this. Once you see the rule...

Teach excluded values with this video. Using a real example, a lecturer breaks down how to find the excluded values of a rational expression. She defines what an excluded value is and completes the problem, explaining each step along the...

Are you working on the distance formula? Derive the distance formula and help your learners by showing them the logic behind the distance formula. This practical video should help conceptual understanding and is appropriate for in-class...

Trapezoids can be tricky. Break down the process of finding the area of a trapezoid with this video! Viewers are given information about the area formula and shown exactly how to plug in information, solve, and simplify. This is a...

This tutorial video will show you how to get rid of that radical in the denominator and rationalize your fraction! Great for in-class or at-home use, this video could be used to supplement a lesson or clarify radicals, rationalizing, and...

How on earth is one to find the area of a rectangle when he doesn't know the width? Using the diagonal of the rectangle, the length, and the Pythagorean Theorem the missing side is determined and the area is discovered. This clip is...

What a great resource! Two learners lead viewers through the process of finding the area of a trapezoid. It's a visual approach that your class is bound to remember.

Add a global perspective to your next math lesson. This learners-created presentation shares things everyone needs to know when they are trying to determine if something is a square. She defines what a square is, provides real life...

Trapezoids can be tricky! Break down the process of finding the area of a trapezoid with an engaging math video. Learners explore area formula and shown exactly how to plug in information, solve, and simplify. 

Do you know the formula needed to determine the area of a rectangular prism? If you don't it's ok, because this video will refresh your memory, then help you use the formula to find the volume of a rectangular prism. Algebra is used to...

Is prism just another mathematical term for a solid? It must be since this lesson is about volume. The teacher illustrates and explains how to find the volume of a rectangular prism and also how to find the volume of a triangular prism....

It's amazing the complex figures that can be made using only a few simple shapes. Following a class reading of the children's book Grandfather Tang's Story by Ann Tompert, young mathematicians use sets of tangrams to create models...

Challenge young mathematicians' understanding of squares with this geometry puzzle. The task is simple, identify as many squares as possible in a 3x3 array. Allow learners to work independently or in pairs as they search for squares,...

This can be used as a critical thinking exercise in congruence or as a teaching tool when first introducing the concept. Four octagons are arranged in such a way that a square is formed in the middle. With this information, geometry...

How are a circle and triangle alike? How are they different? These are the types of questions children will answer while playing this fun geometry game. Including a variety of conventional and unconventional shapes, this activity allows...
