Reflection: Adjustments to Practice Triangle Inequality Theorem - Section 3: Summary + Homework


I had several tables ask if they could have their straw bags back in order to figure out the answer to my question - so I thought that was awesome.  I considered just drawing them a triangle on the board, but I was excited that they wanted to figure it out for themselves.  Once they had their straws, students were able to answer the question with ease.  I think in the future I may add a column to the table about the angles, so that they make note of it during the discovery.

Triangle Inequality Theorem

Unit 7: Geometric Figures
Lesson 9 of 14

Objective: Students will be able to determine if three side lengths can form a triangle.

Big Idea: Any three sides lengths can't form a triangle? NOPE! Students will use straws of various lengths to investigate this theorem.
