Decimal and Percentage Games

Pirates Game Partial

Here at Passy World we are contantly searching the web to find great free stuff that can be used for fun and learning. Because learning should be fun !

But sorry there is no fun for Apple users, because these games are in Flash and Java.

Thanks to Apple's designers, Flash and Java do not run on ipods or ipads.
We do have an ipad here at Passy World, but hope to replace it in the near future with an Android tablet with USB connection and Flash and Java capability.

In this post we present a great collection of free online games for gaining skills in dealing with decimals, fractions, and percentages.

If Blogger sites are blocked in your school, then you can also read this post at our Mathematics blog on WordPress by clicking the link below:


Note that to get to each Game, it is necessary to Click the Link that we have supplied. Clicking the screen shot of the Converter, does not take you to the online app.

(Eg. Because it is a bit tricky to do picture links in Blogger, we haven't connected each screen shots to it's app, but instead provided a direct text link at the end of each review.)

We have certainly checked out a lot of games on the web, and here we give you the best of the best! So let the fun begin.

"Mission Magnetite"


Mission Magnetite involves Fractions and Percents.

In this fun game we click a percent first into it’s bottom circle, and then click it’s equivalent fraction, and then into the last bottom circle the appropriate drawing.
It is a race against time to complete the puzzle before the rocket fills with fuel.

Rounding Decimals to Whole Numbers - Soccer Game


In this Soccer game we practice our knowledge about rounding decimals to the nearest whole numbers. You have to answer each question correctly to get a chance to kick the ball. You must score enough goals to move on to the next level!

To round a decimal to the nearest whole number, look at the digit that indicates the tenth place value. If this digit is greater than 5, you have to round the decimal up. If that digit is less than 5, you have to round the number down. Erase the decimal point.

Example: 31.78 rounded to the nearest whole number is 32, because 7 is greater than 5, therefore we have to round the number up.

56.2 rounded to the nearest whole number is 56, because 2 is less than 5, therefore we have to round the number down to the nearest whole number.

The game also includes rounding to tenths, hundredths, and thousandths.

Note that to kick goals we first mouse click how much power we want to apply, and then mouse kick again to have the kick at goal.

In this baseball math game we practice our knowledge about rounding decimals. We first need to click the mouse on the batter when the ball is pitched to get a home run.

After this we get to answer a rounding off question. Each correct answer gives 1000 points and each incorrect answer takes away 1000 points from our score. The game has several levels, but we need to get enough home runs to advance from one level to the next.
