Worksheet Description

This worksheet combines arithmetic with the concept of prime and composite numbers. Students are required to solve various arithmetic equations and then identify which of the solutions are prime numbers. The worksheet features addition, subtraction, and multiplication problems, and provides space for students to write their answers. Following the arithmetic exercise, there is a section where students are asked to circle all the composite numbers from a given list.

The goal of this worksheet is to teach students to apply their knowledge of prime and composite numbers in the context of basic arithmetic operations. It helps them to not only practice their addition, subtraction, and multiplication skills but also to understand the characteristics of prime numbers as the ones having exactly two distinct positive divisors: one and themselves. The exercise of circling composite numbers reinforces their ability to identify numbers with more than two divisors. Overall, the worksheet is designed to enhance both the student’s computational fluency and their number theory knowledge.
