Prime Factor Tree is an interactive whiteboard resource to use for demonstration or questioning purposes with a class. Select a number from 2 to 99. Clicking “Go” will generate a prime factor tree for that number. The numbers will be obscured by leaves which can be removed by clicking on the leaf. This allows discussion on what the numbers will be before they are revealed.
Once all of the leaves are removed the prime factors can be pointed out.
