These are word problems using GCF and LCM. Students have to decide if cycles are involved or breaking down numbers to find the GCF. This is mostly least common multiple word problems. I have an answer sheet where students will justify their answers by showing their mathematical thinking. I am going to make 4 or 6 sets of these questions on different colored paper and students will rotate and answer the questions. Then we will go over the questions together on the smart board.
