Here are some activities that you can do with Pascal's Triangle (Teachers - these could be used in your lesson plans) -

1. Create a Jeopardy! game. Make a grid with questions (cover up the questions) that have to do with Pascal' s Triangle. When they call on a certain square, take off the cover and read off the question to them. Have a time limit for the students to answer the questions in. Also, putting a big picture of the triangle (or small ones for each student) to help them find answers is a good idea. Give rewards for the students with the best scores.

2. Have the students make a calling tree using the triangle. See the patterns section for more details on how to use paths (listed as "powers of 2") for this activity. Another thing you could try is putting someone's name down and seeing how many ways it can be completed - but, of course, guessing before you figure it out. ("powers of 2" in the patterns section also shows how to make an educated guess for this activity).

3. Use the triangle to create stories. Example:
"Mom, I don't want to go to bed," I groaned. "At least let me climb the stairs as many ways as I can." Using two different types of steps ("hop" covers to steps, "step" covers one) find all the different ways to climb the stairs.

This is a hop-step.

This one is 3 steps.
