2. ZONK! Algebra 1 Midterm Review

3. ZONK! directions 1)Each team will take turns choosing a button that will lead to questions with 200, 400, 600, 800, 1000 points, ZONK!, or a Double ZONK! 2)If a question is drawn, your team must correctly solve the problem to earn points. 3)Drawing a ZONK! means that your team loses the turn and does not earn any points, Double ZONK! means that your team will lose points. 4)When all cards are drawn, the team with the most points wins. HAVE FUN!
