Create a worksheet for grade 4 on prime and composite numbers

This resource covers the essential concepts of prime and composite numbers. A prime number is defined as a whole number greater than 1 that has exactly two unique factors: 1 and itself, while a composite number is a whole number greater than 1 with more than two factors. The document includes visual aids to help students understand these concepts better, such as arrays that demonstrate the arrangement of prime and composite numbers. It also features interactive activities where students can sort numbers from 1 to 20 into prime and composite categories and find factor pairs to classify different numbers. There are also challenge questions and real-world connections that engage students in applying their understanding of these classifications. The resource concludes with a self-assessment section to gauge comprehension.
