Make a worksheet that has three types of problems. Divide the sheet into four parts. For example, if your three types of problems are Translation, Answer the Question, and Unscramble the Sentences, then divide your worksheet into four parts and make the fourth section a mixture of all three types. The students must complete each section. After they finish one section, the bring their sheet to a teacher to be checked. If their answers are all okay, they can move on to the next section. Students who complete all four sections get a prize. This game is good for review.
