Product description
From the author
This printable factors worksheet teaches 3rd-5th grade students about factors and prime numbers. Students fill out a graphic organizer with three columns: the number to analyze, spaces to list all factors of that number, and a column to label if it is a prime number or not. An example is provided, then students analyze 7 different numbers up to 22.
Use this introductory factors worksheet during a small math group to discuss factors and primes and informally assess student mastery. Or assign it as homework or an exit ticket. An answer key allows students to check their work or for the teacher to efficiently grade student responses. This concise one-page worksheet develops number sense skills.

Teaching tips & learning objectives
Learning objectives
Students find all factor pairs for whole numbers up to 22.
Students determine whether a given whole number is prime or composite based on its factor list.
Teaching tips
Use the worked example (4: factors 1, 2, 4; not prime) to model the expected format before students start the remaining seven numbers independently.
The two-page length makes this suitable as a warm-up, exit ticket, or small-group check rather than a full lesson.
Skills covered
Factor-finding — students list every factor of a whole number, such as 1, 2, 3, 6, 9, and 18 for 18.
Prime identification — students use a completed factor list to determine whether a number is prime, correctly identifying only 7 and 17 as prime among the eight numbers given.
