Semester Exam Review Game

1. Semester Exam Review Game Tic-Tac-Toe (Sort-of)

2. Each team will need… • Periodic Table • Flow Chart • Polyatomic Ion List

3. Rules for Classroom • Arrange the numbers between 1 and 15 in your grid. • Answer questions correctly with your teammates to draw a number. • “X” the number on your team’s grid if it appears. • First team with three “X”s in a row WINS!!!

4. If you are studying at home… Play the slide show. Pressing enter will move you through the questions and answers. Be sure that you also look at the review we passed out in class…do not depend only on these questions!!
