This is an engaging scavenger hunt that I created for my students to review the unit Operations with Rational Numbers, standards 7.NS.1 & 7.NS.3. The questions are straight computations mixed with word problems- dealing with decimals, whole numbers, and negative and positive numbers. As the students go from poster to poster, they collect letters along the way that they use to answer a riddle at the end. (The riddle has to do with absolute value)
The download is a Word document that contains an answer key for the teacher with all of the answers and sequence of the posters. There is also instructions guided notes for students follow the scavenger hunt.
The kids absolutely loved it and really were engaged and productive. I suggest giving the students clipboards to hold their guided notes so they can answer the questions right in front of the posters!
