Activity Description Color numbers in Pascal's Triangle by rolling a number and then clicking on all entries that are multiples of the number rolled, thereby practicing multiplication tables, investigating number patterns, and investigating fractal patterns. Coloring Multiples in Pascal's Triangle is one of the Interactivate assessment explorers.

Coloring Multiples in Pascal's Triangle

Place in mathematics curriculum:

This activity can be used to:

• practice students' multiplication skills
• practice students' pattern recognition skills
• introduce Pascal's triangle
• motivate the ideas of fractals

This activity allows the user to identify number patterns in Pascal's triangle. This activity would work well in groups of two or three for about forty minutes if you use the exploration questions and fifteen to twenty minutes otherwise.

Preparations for this activity:

• explain how divisibility by a number is the same as being a multiple since the applet's name is coloring multiples but the directions say color the numbers divisible by the number rolled.
• discuss Sierpinski's triangle.
