Letter War

My youngest is having some trouble deciphering letter case and with recognizing a couple letters.  So, how to make learning letters fun?

I came up with Letter War.  This is like the standard card game of War but instead of a deck of playing cards you print out a deck with upper and lower case letters on the cards.  Now play the game with the letter deck and score like this:

• Uppercase beat lowercase letters.
• The ranking from lowest to highest is: a..z,A..Z
• If the same lower and upper case letter is played then it is war.  This is less common in this deck of course.

Pretty simple I think.  Let's look at some examples:

• E and t are played: A wins
• A and a are played: War
• J and M are played: M wins
• c and v are played: c wins
