Factors & Multiples

Unit 1 of our Illustrative Mathematics curriculum.

Students build on their understanding of area from 3rd grade, starting by creating rectangles with given side lengths, identifying potential areas when one side length is known. They use tiles and diagrams to grasp concepts before delving into new vocabulary. They realize rectangles can have varying side lengths yet yield the same area.

Next, students understand the connection between rectangle side lengths and the factor pairs of its area. They also observe the commutative property of multiplication: rectangles with the same side lengths produce the same area, regardless of their orientation.

Students analyze patterns in factors, multiples, and prime/composite numbers. They utilize these patterns to make predictions, generalize observations, and connect them to real-life experiences.
