The students certainly got a lot of good practice with algebraic expressions just by writing the cards. Unfortunately, most of the games had some errors (2 clues with the same answer, writing that was difficult to read, mathematical mistakes, etc.) in the chain of cards that should loop back to the first card after all the clues and answers have been given (the first card can be any card chosen from the set). I wanted to do this project again this year and decided to create a template for students to use to write the clues and the answers before they make the cards. I wanted the template to be very clear in terms of how the game works and how to write the cards so that each clue is on one card and the answer to that clue is on the next card. I also wanted the students to turn in their template before they make the cards allowing me to review their work and make sure the cards are correct and that the clues and responses will loop through every card correctly. Below is the first page of the template I created--the second page (not shown) has space to make 30 cards in total. I numbered the cards in the columns next to the cards in order to help students keep track of the clues and the answers, but students will need to be instructed to NOT write the card number on the cards so as to not give away the order of the cards during the game.
Here is a link to the template I created.
