Topic 1 Unit 2 Summative is a Grade 4 mathematics worksheet that assesses factors, multiples, prime and composite numbers, common factors, and basic division. Across 16 multiple-choice questions, students identify factor pairs, list factors and multiples, find common factors, count the factors of a number, recognize prime-number definitions, identify the only even prime number, and determine whether numbers are or are not multiples of a given value. Students are prompted to show their work for several items, making their reasoning visible beyond selecting an answer. This free printable worksheet is designed for end-of-unit practice, review, or formative assessment of foundational number-theory skills. It helps teachers check whether students can distinguish factors from multiples, apply factor-pair reasoning, and classify numbers using the correct definitions. The worksheet includes a complete answer key for efficient checking and feedback.

FAQs

What does the Topic 1 Unit 2 Summative worksheet cover?

This Grade 4 mathematics worksheet uses 16 multiple-choice questions to assess factors, multiples, prime numbers, and composite numbers. Students identify factor pairs for 19 and 9, list factors and the first five multiples of selected numbers, find common factors of 36 and 42, count the factors of 50, and classify numbers using prime and composite definitions. Showing work supports factor-pair reasoning rather than answer selection alone.

How can I use this worksheet to teach factors, multiples, and prime numbers?

Introduce the worksheet by modeling a factor-pair chart, such as 1 × 19 for a prime number and 1 × 9 and 3 × 3 for a composite number. Then have students use skip-counting to generate multiples of 5 and 12 before completing the multiple-choice items independently. Ask students to explain how their factor lists support classifications such as 37 being prime, 35 not being a multiple of 6, and 2 being the only even prime number.

What mistakes should I watch for when students complete this worksheet?

Students may confuse factors with multiples, omit a factor pair, or choose an incomplete list, especially when listing the factors of 10 or finding the common factors of 36 and 42. Watch for students who treat 1 as a prime number, overlook that a prime number has exactly two factors, or miscount the factors of 50 after failing to list all factor pairs. In the multiples questions, check that students begin with the given number and add the same number each time.

How do I assign and grade this worksheet?

You can assign Topic 1 Unit 2 Summative as a printable PDF or as a digital quiz on Wayground. The worksheet includes a complete answer key for checking the 16 multiple-choice responses and reviewing students’ shown work on factor and multiple items. For printable submissions, teachers can scan student work with the Wayground for Teachers app to support grading.

How can I differentiate this factors and prime-numbers worksheet for my students?

In the worksheet’s Advanced Settings, adjust font spacing or font size so the multiple-choice options and prompts have more visual space. You can also apply a dyslexia-friendly font to make the factor-list and prime-number questions easier to read, or translate the worksheet into another language. These options modify the worksheet file while keeping its factors, multiples, and classification tasks intact.
