Factor Finders

In this lesson, students first create factor posters for a variety of different numbers that will be displayed in the classroom to be utilized as a resource throughout the school year. They make discoveries about factors using color tiles, represent their discoveries using graph paper, and display their information on poster board as factors of an assigned number. This source addresses the factor finding process which leads to the discovery of prime and composite numbers. The multiplication models this lesson uses can be used for discussions about area. Options for assessment are also included with the lesson.
