We used our equivalent fraction cards to play "Go Fish!
The students had a great time and did a good job. In the first class, I didn't "make" the students write down the lowest terms of the fractions in their hands, so it took some of them a little longer to re-reduce their fractions when another person asked for a certain fraction. These students commented that the game really made them think and that it was good when someone made a mistake, because they were able to recognize that a mistake had been made! Good thinkers!
I had later classes reduce their fractions and record that on notebook paper, and it definitely helped them to play the game more smoothly.
We did alter the rules a bit: each student started with 7 cards, and students continued to play until all the cards had been used, rather than ending when someone was out of cards.
Overall, successful game!
