I broke out the Sum of Three again. I just love this activity! I posted the student sheet in our online course, but you can email them. Students work on groups of three problems each, at their pace and in the order they want. There are four groups for this particular activity. Students may work alone, in pairs or in groups of three - I would not have groups larger than three since that would leave the others with nothing much to do. Once students have completed one group of three problems (groups are listed below), they take the sum of all of the answers and put the sum into the form (linked on the student sheet). If they are correct, they move on. If they are incorrect, they will get an error message and will need to figure out what went wrong. They do this for all problem sets until they can submit the form.
