### 123 Switch! (Game to Practice Adding/Subtraction Integers)

I found another great game to practice adding and subtracting integers.  The game really forces students to be flexible in how they think of number combinations.  I know that is an area that my kiddos struggle at times and they need to be much more flexible than they are.  So, when I found 123 Switch! on Tom DeRosa's blog, I Want to Teach Forever, I was thrilled!

Tom has a hand made template that students drew in their notebooks.  I see the value in that and would prefer that, but I know my kiddos and they need a game board.  So I made a template for addition and subtraction.  I am going to print them out on some fun colored paper and then glue them back to back.  With some quick lamination, they should be ready for the next school year!

The first thing you do is pass out 7 cards to each player.  The black cards are positive and the red are negative.  The first player puts down a true equation based on the cards in their hand.  If they can't, they need to select cards from the draw pile until they can.

The next player can change 1, 2 or 3 cards by placing a card on top of one already on the board with one from their hand.  In the picture below, I could replace the 6 of diamonds with the six of hearts.  I could replace the 9 of spades with a 7 of clubs.  Then replace the 6 of diamonds with a 4 of diamonds and still have a true statement without changing the 3.  I could also just replace all three cards.  The goal is to be the first person to get rid of all of his/her cards.

The game becomes more challenging when you have to make subtraction equations.  I like that the game is challenging and competitive enough to keep the students interest.  Not to mention, it's  a great way to practice!

Here are my templates for the game boards.  I also made a direction sheet for the students.
