My name is Jennifer Goltsberg and the following was developed for my own children. Each Bingo card is completely unique and across all the cards all the letters are represented (with the exception of the 3 letters that have no words beginning with them).
Personal Note: I printed the game and laminated the cards. I would recommend printing the squares used to match the bingo cards in a different color. In retrospect the color contrast would make it easier to see when a card is full.
