Description:

Using square pattern blocks, algebra tiles, or paper, this cooperative activity introduces students to the concept of displaying a numeral as the area of rectangular arrangements. Student goals include understanding that some numbers can only be represented by two different rectangles that have either a length equal to one unit or a width equal to one unit (prime numbers); whereas other numbers can be represented by more than two different rectangles (composite numbers).
