Here are some responses to my question, "What is a suggestion that you have to make the activity better?":
"None it was so much fun!"
"Make it longer somehow."
"I think it would have been more fun if you could chose to add or subtract them before you rolled. Then you could actually roll 1 but it would also add an element of danger because you could accidentally roll a negative number."
Below, you will find the results of a survey that students completed to show their interest in the activity and their understanding. They responded on a scale of 1 to 5, where 1 indicates the least and 5 indicates the most.
