Mr. Boozman introduces the concept of figure eight number patterns, focusing on identifying changes in patterns using arrays. The video explores rectangular numbers, demonstrating how to create and extend patterns using multiplication and addition. Students learn to analyze factor patterns and apply deductive reasoning to understand number increases. The session concludes with instructions for further exercises, including triangular number models.
