This activity can be used in different ways. One way is at lower grades by using the second and third columns only in order to practice prime factorization. The other way is to use the first, third, and fourth columns to practice simplifying radicals by using prime factorization and factor pairs. This activity consists of 24 numbers, ranging from 18 to 153, with none of them being perfect squares so that students are practicing the skills rather than recall of perfect squares at this point. Preparation time is minimal, and this activity engages students in not only practicing skills but also in cooperative learning and other beneficial activities.
