Card Games to Develop Number Sense

I think almost everyone who teaches early elementary has heard about Make 10 Go Fish to help develop number sense around the benchmark number of 10.  But have you heard of Make Teen Go Fish?  Towards the end of the school year I got to attend a 2 day workshop by Illustrative Mathematics.  One of the activities was to take a task off the website (www.illustrativemathematics.org) and modify it.  The task my partner and I choose to look at was Teen Go Fish.  Click the link to take you to the full task, but basically you have cards with the teen numbers written on them and kids play Go Fish asking for numbers in the teens.  This task helps them identify the numerals, but it got me thinking about a way to modify the task to help develop number sense.  Instead of just identifying the numerals I wanted a way that would help them develop the understanding that each teen number is 10 + some more.

I wanted to give them a visual that would help them see 13 as 10 and 3; Ten Frames were just what I needed.  I created a deck of cards that had 18 full ten frames and 18 ten frames that were not full, two each for the numbers 1-9. Then I constructed the “board” for each player that had the numerals for 11-19.  This way they still get the practice of recognizing the numeral, but also get practice seeing the numbers in a number path.  As you can see in the picture, we were using playing cards that I created and had the ten frames printed on the blank side.  You can purchase the blank playing cards at www.plaincards.com and then use my Ten Frame Playing Cards PDF to print them.  I also included other ideas for games to play using these cards, but here are the full directions for Make Teen Go Fish and in case you don’t know about Make 10 Go Fish I included those below as well, but I’d also love to hear about any other games with ten frames that you use to help develop number sense.
