This is a fun, end of the year math activity that reviews several standards in one activity. You will cut out the answer cards and hang them around the room. There are sixteen problems altogether. Eight are word problems and the others are computational. The students will first solve the problems, then they will go look for the answer on the answer cards. If they can't find the correct answer, they know they have made a mistake. When they find their answer, they write down the letter that is given on the card. When all the letters are found, they fill in the correct answers into the riddle.
