What's Inside

This resource includes five pages of math problems, totaling 60 questions, designed to build mastery in finding a fraction of a number. Each page presents 12 unique problems in a clean, easy-to-read format. A complete five-page answer key is provided for quick and easy grading or student self-checking.

Skill Progression

This worksheet set follows a gradual-release model.

• Guided Practice: The first page can be used with a teacher to demonstrate the method of dividing the whole number by the denominator and multiplying by the numerator.
• Supported Practice: The next two pages allow students to work in pairs, solidifying their understanding across 24 problems.
• Independent Practice: The final two pages serve as an excellent tool for independent practice or a formative assessment to gauge mastery.

This "I Do, We Do, You Do" structure builds student independence.

Standards Alignment

This worksheet is aligned with Common Core standard CCSS.MATH.CONTENT.4.NF.B.4, which focuses on multiplying a fraction by a whole number. It also reinforces the Grade 3 foundation of CCSS.MATH.CONTENT.3.NF.A.1. Both standard codes can be copied directly into lesson plans or curriculum maps.

How to Use It

Use this as independent practice after a lesson on multiplying fractions by whole numbers. For a formative assessment, have students complete one page in a timed (10-minute) session to check for understanding. Observe their calculation methods to identify areas for re-teaching. The full set should take a proficient student about 20-30 minutes to complete.

Who It's For

Designed for fourth-grade students, this worksheet is also great for fifth-grade review or advanced third-graders. Its clear layout makes it accessible for a range of learners. It pairs well with visual fraction models or an anchor chart showing the procedural steps for finding a fraction of a set.

Mastering procedural fluency with fractions is a key predictor of later mathematics achievement. This worksheet provides focused practice aligned with standard CCSS.MATH.CONTENT.4.NF.B.4, helping students learn to efficiently multiply fractions by whole numbers. Research from the RAND Corporation highlights the importance of such procedural skills as a foundation for algebraic thinking (RAND AIRS 2024). By offering 60 distinct problems, this resource moves beyond conceptual introduction to support the automaticity needed for higher-order problem-solving. It enables students to apply the understanding that finding 3/4 of 16 is equivalent to (3/4) * 16, a critical connection for their mathematical development. The high volume of practice aligns with findings that repeated, structured practice is effective for skill consolidation. This targeted approach ensures students build the robust skills necessary for future success in math.
