What's Inside

This 5-page PDF includes a problem set, exit ticket, and homework. Students will solve 9 problems focused on listing factor pairs, identifying multiples, and classifying numbers as prime or composite. A full answer key is included for efficient grading.

Evidence of Mastery

Tasks provide clear evidence of student mastery for CCSS.MATH.CONTENT.4.OA.4. Problems progress from listing factor pairs to determining if a number is prime or composite. Teachers can use the included problem set, exit ticket, and homework to gauge understanding of each component of the standard and inform instruction. The structure makes it easy to track progress.

Standards Alignment

This worksheet is directly aligned with CCSS.MATH.CONTENT.4.OA.4. It requires students to find all factor pairs for whole numbers up to 100, identify multiples, and determine whether a number is prime or composite. The standard code can be copied directly into lesson plans, IEP goals, or district curriculum mapping tools.

How to Use It

Use the problem set for guided practice after direct instruction. The exit ticket is a quick formative assessment (under 5 minutes), and the homework pages reinforce concepts. Observe students' methods for finding factor pairs to identify systematic thinking or areas of confusion. The entire packet should take approximately 25-40 minutes to complete.

Who It's For

Designed for 4th-grade students, this resource also supports 5th graders needing review or advanced 3rd graders. It pairs well with a 1-100 chart to help students visualize number patterns and relationships before beginning the tasks.

This worksheet provides focused practice on CCSS.MATH.CONTENT.4.OA.4, a critical standard for developing number sense in upper elementary students. By engaging with tasks on factors, multiples, prime, and composite numbers, students build a foundation for later work in fractions and algebraic thinking. Research emphasizes the importance of procedural fluency built upon conceptual understanding. As noted by Fisher & Frey (2014), well-structured independent practice is a key component of a gradual release of responsibility model, moving students toward confident and autonomous problem-solving. This resource provides that structured opportunity. It contains 9 problems across 5 pages, including an exit ticket and homework, allowing teachers to gather formative data and ensure students can not only find factor pairs but also determine if a number is prime or composite, a key skill for future mathematical reasoning.
