Card game of 72 cards. Each card contains an expression with an exponent or an equivalent expression or the simplified expression. Twenty-four sets of 3 cards. Each set has 3 equivalent expressions and makes "a book". A "recording sheet" is included for easy grading and to help students self assess. Key is included. When making each deck, I marked the back of each individual deck so that I could tell the cards of that deck in case a card was dropped and I found it after class. This helped me quickly identify the correct deck so I was ready for the next incoming class. I ran the cards on cardstock most of the time, but I have used regular copy paper. Card games are an excellent way to save paper, even though it may take a little more time to ready the decks. Once your cards are prepared, you simply have to print the record sheets. I recommend printing the recording sheets the same color as the cards. If class time is short, only print half the deck and adjust your record sheet to reflect the correct number of problems. I have my students sort cards face up into 3 rows of cards:the exponent exzpression, the equivalent expression, and the simplified expression. Once cards are sorted, students make "books" This is a great partner activity..
