Math Planet: Algebra 1: Radical Expressions: The Distance and Midpoint Formulas

Small groups work through two guided activities to derive the distance and midpoint formulas for the coordinate plane. The activities begin with concrete examples and move to abstract.

Who says math is boring? Turn dry concepts like properties and vocabulary into an interesting lesson! Examine the commutative and associative properties of addition and multiplication using geometric reinforcement. Through collaboration,...

Go for a walk in the mall. Pupils find distances between stores on a diagram of a mall on Quadrant I. The scholars also determine the midpoint between a store and an entrance to the mall to then create their own paths and determine their...

Many times budding algebrists are fine when plugging specific numbers into expressions, but less certain when the range of acceptable values is undetermined. This detailed presentation helps the class move from the point value to...

Provides detailed information about the graph of a radical function through the use of examples and a brief video lesson. [2:10]

Provides an explanation, examples, and a video lesson all related to the radical equations. [3:02]

Provides examples and a video lesson that illustrates how to compose a mathematical expression.

Let's meet in the middle. Given two points on the coordinate plane, pupils use the interactive to find the midpoint. The interactive provides a graphical display of the midpoint and the midpoint formula with the coordinates of the...

Radical, dude! The resource provides an explanation on how to simplify radical expressions. It makes clear that radical expressions are ones that are strictly numerical but also are algebraic expressions. One of the problem sets...

Learn how to use the order of operations when working with expressions through discussion and a video lesson.
