Teach or review with your pre-algebra students how to combine like terms playing the game Uno! The rules are exactly the same, however, the numbers have been switched out for variable expressions. Great for pre-algebra students to continue practicing with positive/negative numbers, decimals, and fractions.
When printing, make sure to print double sided and "short flip" the pages. I print on normal paper then laminate, but you can also print on card stock to save some time.
