I use this game in between writing sentence activities to liven up class. Students on two teams get the number 1-15. They have to write the correct form on white board so everyone is preparing and consulting classmates. When their number comes up they have to be first and correct to either lift the board up or I bought fútbol suckers and had them grab the sucker on a stool in the middle of the classroom (they love this). If they are wrong anyone on the other side can steal the point (or sucker). The second slide is a fun opportunity for an extra point. If they can make a goal by sliding the ball into the net they score and everyone cheers "GOOOOL". My sentences practice preterite imperfect but could be used for many other grammar activities.
