Once everyone receives a file folder of materials, have the students draw 7 X’s on their
board. These are the “ships” that the other person is trying to sink. (We suggest having the boards laminated and allowing the students to use a dry erase marker to mark their X’s.) Once the X’s have been marked, have the students begin solving problems on the
worksheet in their folder. After partner 1 solves a problem, he/she will check his/her
answer with partner 2. Partner 2 will use the answer key provide to him/her to verify if
partner 1 is correct or incorrect. For example, Partner 1 factors x^2+10x+16 and finds the answer to be (x+2)(x+8). Next partner 2 would check to see if he/she had an X over (x+2) and/or (x+8) . If partner 2 did, he/she would have to erase the X. The partner with the most X’s at the end wins!
