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.

In this one or two player millionaire game, we can practice changing fractions and decimals into percents. It is well done and lots of fun.

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.

Rounding Decimals - Baseball Game


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.

In this flying game we click the mouse button to make our helicopter go up, and let go of the mouse button to let it go down, as it flies through the city.

If we fly too high or too low, or hit the decimal, the game ends.

The game takes a while to get used to, and it is very annoying that there is not a restart button. To restart a game we have to reload/refresh the web page with our browser.

The sad thing is that a large percentage of Apple device owners will never got to play these games, because Apple does not support Flash and Java.

  1. Dear Passy
    Thank you for such a comprehensive selection of activities for Gr 3/4 students to practise their fractions concepts. My students will enjoy them next week.

  2. Hi Mrs Lynch, glad to hear the students will be having fun, because Maths should be fun! I have recently just started a WordPress blog devoted exclusively to Mathematics. This Games post is also featured there. It might be handy, if your school blocks Blogger sites. This is the link:
    Enjoy, Passy.
