This is a discovery activity where students will use plastic pieces of various lengths that snap together forming sides of triangles in order to discover the relationship between the side lengths of a triangle and the types of triangles they form, if they even form a triangle.
This can be done with different size popsicle sticks, straws or even string.
At the end of the activity there are essential questions that students are required to answer, leading them to the properties of triangles they are trying to discover such as:
Were you able to make a right triangle? If yes, explain which pieces you used.
Take a look at your trials. Compare the lengths of the sides and determine when you were able to make a triangle, verse when you were NOT able to make a triangle. Do you notice anything? Make a hypothesis to determine what must be true about side lengths in order to create a triangle.
