War with Decimals and Fractions

maths game - fractions and decimalsIt's over twenty-years since I first played this maths game with Primary-age children... but that doesn't stop it being an excellent way for children to develop their understanding of fractions and decimals.

You will need two copies of the cards cut from the downloadable* file. That's 48 cards in total.

The cards are shuffled and dealt face-down between the two children who are playing. The players keep their 24 cards in front of them. Together, the children turn over a card from their own pack (a little like the game of snap).

They both look at their cards and decide who turned over the fraction or decimal which indicates the larger amount. Whoever has the turned over the larger card keeps both.

fractions and decimals gameIf both cards show same amount (fraction or decimal) then the players declare 'War'. At this point each player places their own card face-down to one side and deals two more cards (unseen) face-down on top of the first. The next card they turn is the 'explosion card' - they turn it face up together. Whoever has the larger amount on the card here takes all of the cards in the 'war'.

Cards that are taken are always placed at the bottom of the player's pack of cards. The first player to take all of the cards is the winner.

This is going to ideal, especially as our theme for the first two terms is WW1 - should get the children really engaged - thanks mathsticks :)

A great idea - my class have really struggled to pick up the relationship between fractions and decimals. Hopefully this will be an exciting way to embed and consolidate what we have been doing. I'll probably start as pair vs pairs whilst LA children get to grips with the game. Thanks!

A great game. Have played similar in the past, but this encompasses more skills and has clearer rules. Thanks.

I like the idea of a back to back mobile! I hope that my middle ability y6 children will improve their fractions knowledge through playing the game.

Thanks for this resource.

Thanks for this resource. I'm going to use the game idea but adapt it for my lower ability Year 3s by having fractions of shapes, fractions of groups of objects and the amount written as a fraction.

Thank you so much - this is a brilliant resource and one that I know my children will love.  It will really help them to understand the link between fractions and decimals and it is being done in a way that means they don't feel like they are learning :)  Yet again, you have saved the day :)  I don't know what I would do without your amazing resources Mathsticks :)

This will really appeal to the boys, although I'm not sure I should be encouraging their love of war.

I tend to agree with your

I tend to agree with your latter point. But we kept the term only in the title and the cards themselves cannot be said to 'encourage' war-like attitudes. We did think quite carefully about thsi before releasing it - the consensus of opinion was that 'war' in this context was seen in an innocent, child-like way... if that makes any sense!

Hi  I sometimes play

Hi  I sometimes play equivalent fraction snap, but this idea is much more fun.  Just one suggestion - could you make the decimals equivalent to the thirds fractions show as recurring please?  Otherwise children might get the idea that the decimal stops after 2 places.  Thank you.

Thank you for this resource. It will be great for the children to use rather than a worksheet and it will also create plenty of speaking and listening.

This looks like a great resource, and I'm very happy to use it instead of another worksheet. Partner work and talk are always better! Many thanks.

 Yet another great resource. This will make my pupils think and help them to reinforce their understanding of decimals and fractions. I am so pleased that I found this website and so wil my colleagues when I go back to school on Monday and tell them about it.

Thanks for yet another activity that beats the boredom. For some reason, fractions and decimals strike fear in teachers and students alike and anything that will help all involved is quickly snapped up to provide as much support as possible! Keep up the great ideas!

The cards within this game

The cards within this game are deliberately plain to make sure the typeface is clear and legible. However, if you want to add colour or decoration you could always photocopy them onto coloured/patterned card. In the past I have asked children to add simple cartoon illustrations to a set of cards before they are cut up and laminated... maybe this would be a useful approach.

My class will love this game perhaps a fraction wall to help them so they have a key visual to help them. This is a great concept that will really help my kids.

 I plan to back-to-back the equivalent fractions and decimals and make a hanging mobile.  That way kids will have a visual that does not take up wall space.  Even the chn who are not yet up to comparing the two will have access to the information.
