## Volume of Prisms: Volume of a Rectangular Prism - Fractional Cubes

Icon: To find the volume of a rectangular prism, divide it into fractional cubes, find the volume of one cube, then multiply that area by the number of cubes.

## Volume of a Rectangular Prism: Fractional Dimensions

Icon: Find the volume of a rectangular prism with fractional dimensions.

## Area and Perimeter of Polygons: Finding Area by Rearranging the Parts

Icon: Learn how to rearrange the parts of geometric figures to find the area.

## Coordinate Plane: Reflecting Points

Icon: This tutorial explains that a reflection point is the mirror point on the opposite axis--like looking at a mirror image of yourself, but flipped.

## Surface Area: Nets of Polyhedra - Introduction

Icon: A polyhedron ("polyhedra" is plural) is nothing more than a 3 dimensional shape with flat surfaces and straight edges. (Think: cube.)

## Area and Perimeter of Polygons: Finding Area by Breaking up the Shape

Icon: Find the area of odd-looking geometric figures by breaking the figure up into smaller, simple geometric shapes, then calculate and total their areas.

## Surface Area: Using Nets of Polyhedra

Icon: Surface area is the sum of all the areas of all the shapes that cover the object's surface. Let's use the net of polyhedra as an example.

## Perimeter and Area of Non-Standard Shapes: Area of a Parallelogram

Icon: What's interesting about the opposite sides of a parallelogram? That's right....they are parallel! Let's find the area--base x height.

## Volume of a Rectangular Prism Word Problem: Marbles in a Fish Tank

Icon: Learn how to find the volume of a rectangular prism through a word problem.

## Perimeter and Area of Non-Standard Shapes: Area of a Kite

Icon: If you were going to make your own kite out of a piece of cloth, then knowing the area of the kite would be helpful, right?

## Area and Perimeter of Polygons: Area of a Strangle Quadrilateral

Icon: Some quadrilaterals are oddly shaped so break it up into shapes for which the area is more easily determined.

## Shapes on the Coordinate Plane: Quadrilateral

Icon: In this example we're given the coordinates of the vertices and asked to construct the resulting polygon a quadrilateral). This is fun!

## Perimeter and Area: The Basics

Icon: This geometry primer explains the basics of perimeter and area.

## Perimeter and Area of Non-Standard Shapes: Area of a Trapezoid

Icon: A trapezoid is a cousin of the parallelogram. However, in a trapezoid only two of the opposing sides are parallel. Here's how to find its area.

## Perimeter and Area of Non-Standard Shapes: Quadrilateral Overview

Icon: Learn the definition of quadrilaterals, the difference between concave and convex quadrilaterals, and about trapezoids, parallelograms, and rhombi.
