    This resource has been matched by a member of the Brokers of Expertise standards matching team. A great problem that I would do with 5th - 8th grade students.

Description

This activity by Math Forum presents a surprising fact hidden in Pascal's Triangle. Students create a "flower" by coloring the six numbers surrounding a given number in the triangle. Multiplying alternating "petals" results in a surprise. Students are asked to look at prime factorizations in order to better understand what is happening. In addition to exploring an interesting problem, students get some good practice with multiplication, factoring, and prime numbers.
