This activity has students discover the rule for the side lengths of a triangle. Students roll dice to determine side lengths. Students then determine if it is possible to build a triangle with these lengths. A worksheet is included for students to keep track of their findings and discover patterns. Using pipe cleaners of different lengths is optional, however having some physical representation of the side lengths will make this activity more meaningful. The answer key/rubric link leads to a blank spreadsheet. The extension to this activity involves identifying the type of triangle (acute, right or obtuse) and although it is an appropriate extension, it needs further development.
