10 Out - math card game

Today I told my dd to write down addition facts where the sum is 10 - "Which numbers make ten?" are the words I use with her. While she was writing them and using abacus, this math card came 'popped' to my mind...

I can't claim it as my own, because I have this 'feeling' that I've read about it somewhere, sometime, but since I can't remember when or where, I can't give credit to where credit might be due.

I will just name it "10 Out" - a math card game.

Anyway, this is how it goes:
Take away the 'picture' cards and joker from normal playing cards. Then deal 10 cards to each player; put the rest of the deck in the middle. The goal is to get rid of all cards in your hand.

Find all pairs of cards in your hand that add up to a ten (or single 10's) and discard them. Then you may ask the player left to you for one card, and if she has it, she has to give it to you.

For example, say you have 2, 3, 8, and 1 left in your hand. You ask the person next to you if he has 9 (because 9 and 1 would make ten). He has, and gives it to you. Then you form another ten and discard your 1 and the 9.

Then the next person asks the player to their left for one card, and on around.
You could modify it so that each players just blindly hands one card to the player on their left.

Then, once nobody can discard any more cards, every player takes one card from the deck in the middle, and checks if they can form a sum of ten and discard cards. Again each player will be allowed to ask for one card from their left neighbor, if they want to (or everyone hands one card blindly to the player on their left). Continue until someone wins.

I feel this can easily make kids memorize addition facts with sum 10.

Then, of course, next math lesson it will be time for "9 Out" and "8 Out" and "11 Out" and others!

We've played this for years. It's a take-off on the traditional game Fish, which may be why it seems vaguely familiar to you. We also play 10's Concentration (or Memory) with the same deck, again matching pairs that make 10.

Another variation for your 10-Out game: allow combinations of more than two cards. You could let a player set down at 6+3+1 as a set of ten, if you wish. Since you are dealing ten cards at a time, this might lead to some strategic thinking. "Which way should I combine the cards in order to have the fewest left in my hand?"

Card games are a great way to practice math facts and reasoning skills. One of these days, I need to finish writing my math games book. I wonder if I could publish it as an ebook, like yours....

We play this, too, and even the preschooler can play, now that he can add to ten. We leave in some dummy cards --such as jokers and the reorder card, or kings or something-- to stand for zero.

Right Start Math uses a game similar to this called "Go to the Dump," which is like Go Fish, but they use a deck of number cards with a zero. We play it quite a lot, and ask the entire group for the missing card to speed things up. I like your idea of passing cards around to speed up play. Playing faster makes it more fun, even for us grown-ups. And it is more fun with 3 or 4 rather than just 2 players.

I recently read with interest your article about creating your own card game. I had a few simple card game ideas floating around in my head and began researching ways to create them without printing them out and gluing them on old cards.

I found several places (print on demand places) where you can upload cards you create on the computer and they will make the deck of cards for you.

The places I have used are ArtsCow and The Game Crafter. However, there are others such as Guild of Blades and Superior POD.

You can see my game, which can be printed out and played for free, at the following:

I was wondering if I can use this game on my math games website.

I want to put a link back to this page of course.

Please reply.

Feel free to put it on your site, but put a link back to this blogpost.

In the example, you said that you had 2 and 8 in your hand...I thought it might reduce clarity.
I think math games should be a big part of learning math. My children might not really want to do their math lesson, but they were always eager to play games. I made up games like you have as we went along. What ever they needed to learn, I would incorporate it into a game. They learned super fast when ever it was part of a game.

for my point of view math game is one of the biggest part of learning.I can use this game on my math games website.
