This site allows students to explore the patterns that arise by shading all numbers in Pascal's triangle that are divisible by n for a given n.
Type of Material:
Demonstration, exploration module
Technical Requirements:
Runs in Win98 with Explorer, on Mac with Netscape or Explorer.
Identify Major Learning Goals:
Students learn to recognize and describe patterns and investigate pattern questions that arise when the divisor changes, or when it is composite instead of prime.
Target Student Population:
Juniors and seniors in high school, early college
Prerequisite Knowledge or Skills:
A little familiarity with Pascal's triangle, some knowledge of prime numbers and divisibility.
Content Quality
Rating:
Strengths:
Nice set of discussions questions to get students to study a phenomenon, describe it, and draw some conclusions. Very attractive graphics. Fractal pictures might interest students and make them curious.
Concerns:
Site is written with one purpose, so explores only one aspect of Pascal's triangle
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
Interesting questions and patterns that arise from a very easy to understand/apply process. Even students who do not like math might enjoy this.
Concerns:
The focus is narrow.
Ease of Use for Both Students and Faculty
Rating:
Strengths:
Very simple idea, well laid out, easy to use, attractive. Links to related sites.
Concerns:
None.
