We used this in groups of 5 in my 4th grade class. Each student was able to create a machine with help from the group. After creating the machine, they used the activity cards- reading and answering the questions for that machine. I went around and checked their answers and then they moved on to the next machine. This is a great tool for understanding simple machines, student led learning, and cooperative learning. I would also recommend the activity cards that go with it.
