# Math Sites and Calculators for Kids! Most kids hate to look at their math books. Imagine having to count all of those numbers in your head. It may seem pointless at first, but elementary math does play a role in the real world. Elementary math teaches kids to think about the world around them in numbers. Kids learn how to use numbers by counting, subtracting, adding, multiplying, and dividing. Elementary students must know how to solve a problem using number theory, elementary algebra, and geometry. Most kids understand basic mathematical concepts, such as time, percentages, decimals, fractions, length, area, and volume before moving onto middle school. This may sound unbelievable for a first, second, third, fourth, and even fifth grade student who loves to only play video games. Oh, wait, games and math do go hand in hand. In fact, kids can go home and learn all of their favorite math problems by playing special math games right on their own computer. Come check it out!

## Using Numbers

Math games can teach kids how to use numbers in different ways. Kids can learn the principles of the number line, place value, ordering numbers, the powers of 10, roman numerals, whole numbers, and much more. These games teach kids basic math definitions, formulas, and mathematical methods to solving these problems. It also gives them a chance to practice before taking their first test. Give these games a shot. You won't be disappointed!

## Number Theory

Number theory sounds boring to the average kid. Number theory deals with integers, which is a big word for whole numbers. A whole number is any number that does not have a fraction or decimal point. In other words, the numbers 1, 10, 90, and 1050 belong to the group called integers. The numbers 1 and ½, 1 ½, or 1.5 are not integers. Number theory also teaches kids about Pascal's triangle, prime and non-prime numbers, prime number factorization, divisibility rules, squares, and square roots. Play the following games to really understand these basic principles.

Elementary Algebra

Eleven to fourteen year old kids start to feel the pressure that math brings them. Elementary algebra will have your head spinning with new words and ways to solve problems. Learn the difference between a function, variable, expression, and quadratic equation with these amazing games. These games will have kids solving linear equations in no time!

## Length, Area and Volume

Entering the third and fourth grades may seem harder than the first and second grades, especially when it comes to math. Kids move from counting shapes to understanding their perimeter and area. Those are two big words for calculating the length and width of squares, rectangles, and triangles. Fifth graders move on to harder concepts, such as determining the volume of cubes and prisms. All of these words and concepts may seem strange to you. Play these games to get a better understanding to ace your test!

## Time

Time measures an ongoing sequence of events, including the past, present, and future. Time is measured in seconds, minutes, hours, days, weeks, months, and years. People use clocks to keep track of time. Clocks have numbers counting from one to twelve. Clocks also measure the time of day, such as morning, afternoon, and evening. Time can be a very difficult concept to understand. Play these games to learn how to tell time.

## Geometry

Get out those rulers, protractors and compasses to learn how to create wonderful geometric shapes. Use these worksheets, printables, and games to learn how create circles, rectangles, triangles, and even quadrilaterals. Learn the proper measurements when working with angles and cubes. Cut and paste to create your own three-dimensional shapes or play a game to create a virtual copy. Impress your parents and teachers with your geometric creations.

## Graphs

There are many types of charts and graphs that can be used for general or specific use. Some are pretty easy to understand while others may be a little tricky. Line graphs show how something changes over time. A line graph has an x-axis that runs horizontal, and a y-axis that scales vertical. The x-axis typically shows time measurements. The y-axis shows the numbers for the object being measured. Line graphs are great for plotting data with ups and downs. Bar and pie graphs are also pretty common, too. Play these games to learn more about graphs and how they are used.

## Percentages

Percentages are part of a number expressed with % sign. A percent refers to a number's relationship to 100. For example, 10% of 200 would equal 20. Every number has 100 percent in it. Ten percent would be the expression of ten equal parts in 100. Use these activities, printables, and games to gain a better understanding of percentages.

## Decimals

A decimal is a dot used to separate a whole number from its fractional part. For example, in the number 46.9, the dot separates the 46 from the 9. In this example, the 46 represents the whole number whereas the .9 is the fractional part. The .9 really means 9 tenths. Therefore, 46.9 is 46 and nine-tenths. Play these games to gain a better understanding of decimals.

## Fractions

A fraction is part of a whole number. A fraction has two parts: the denominator and numerator. The denominator is the bottom number. The denominator says how many parts the whole number is divided into. The numerator is the top number that says how many you have. For example: ¾ or three-fourths of a whole pizza represents three uneaten pieces. Play these games to gain a better understanding of fractions.
