This Applet allows students to find and see patterns using Pacal's Triangle.

How to use it:
Your task is to highlight all of the numbers that are divisible by two. To highlight your desired hexagon first in the tool bar select the tool "Divisible by 2" then click on the very bottom point of the hexagon then click on the bottom right point, this should highlight the desired hexagon.
To delete a highlighed area select the Pointer Arrow and select the desired area then just push the Backspace button.
Once you have found all of the numbers you can check your work by Showing "Numbers divisible by 2"
You can then reset the applet (by pressing the reset button in the top right corner of the screen) and repeat for finding numbers that are divisible by 3.

Then Answer the questions below
