Results Of Rolling A Set Of Dice, Sarah Jacka

#### Results Of Rolling A Set Of Dice, Sarah Jacka

*Lesson Plans*

We will, as a class, investigate the results of rolling a set of dice. We would like to learn about the outcome when the pair are rolled and their sum is found.

Many students initially predicted that when dice are rolled, each sum from 2-12 is equally likely to be rolled. They assume that since each side of the die has a 1 in 6 chance of being rolled, it would make sense that each sum would have an equal chance at appearing.

We will use many tables, charts and graphs to investigate the students’ claim that each sum is ...

Students were to investigate different situations where these energies are evident using various modeling technologies and design a tangible model they could use to assist in explaining the difference between the two energies. Once students designed these models, they needed to be able to explain where these energies exist in these situations using verbal explanations, mathematical equations, physical displays, and ...
