Isle of Math

Arithmetic: the branch of mathematics dealing with the properties and manipulation of numbers[br][br]The Isle of Mathematics floats in a Sea of Arithmetic. All special fields of mathematics are dependent on the "Laws of Arithmetic".
Geometry: earth measurements; a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space[br][br]Algebra: the language through which we describe patterns; it allows users to make general rules for arithmetic patterns; saves time for repetative processes[br][br]Trigonometry: a branch of mathematics that studies relationships involving lengths and angles of triangles.[br][br]Analytic Geometry: a branch of algebra that is used to model geometric objects - points, (straight) lines, and circles[br][br]Calculus: the mathematical study of change, in the same way that geometry is the study of shape and algebra is the study of operations and their application to solving equations[br][br]More advanced chart: [url]http://meta.math.stackexchange.com/questions/6479/a-graph-map-of-math-se[/url]

Multiplication Practice

Small tool for students to practice multiplication tables. I recommend learning through the 16's. It is useful for factoring fractions and quadratic expressions. You can [b]change Max value[/b] by clicking on it and typing a new Max value.

The Real Number System

Here we will study the Real Number System. The vocabulary in this lesson will be used in every mathematics class.
Students are expected to know these concepts and vocabulary words for daily use.

Comaparing Fractions

Can you find equivalent fractions with a common denominator that make it easy to compare the size of the [color=#1551b5]blue[/color] and [color=#0a971e]green[/color] fractions?

Percentage Problem

Percentage is one of life's continual problem. Everyone uses them daily, sometimes without knowing it. There are basically 3 unique percentage problems, all are presented here:[br]1) Find the percent of a number. (Usually calculator ready.)[br]2) Find what a number is when you are given the % and the whole.[br]3) Find what percent a number is of another number.[br]The second two require a little algebra to work. Here this algebra has been set to be a proportion which solves easily with all 3 types.

Writing Equivalent Fractions

Rewrite equivalent fractions using smaller or larger denominators.

Measuring Angles with a Protractor

Move the LARGE POINTS to move the protractor around. Measure the colored angle you see here and enter its value in the input box (upper right).

Square Numbers

ā€¢ a number which can be represented in the shape of a square.[br]ā€¢ a number that results from multiplying an integer by itself.[br]ā€¢ also called a perfect square.
