What's Inside

This download includes a 3-page student assessment and a 2-page answer key. It features 29 problems across eight sections, covering conversions between fractions and decimals, value comparisons, and word problems.

Evidence of Student Mastery

Aligned to CCSS.MATH.CONTENT.5.NBT.A.3, this assessment provides clear mastery evidence. Tasks measure a student's ability to handle fractions and decimals in multiple contexts. Teachers can use the results to see if a student is approaching, meeting, or exceeding standard expectations. The included answer key allows for quick scoring for gradebooks or IEP progress monitoring.

Standards Alignment and Curriculum Integration

Primarily aligned with CCSS.MATH.CONTENT.5.NBT.A.3 ("Read, write, and compare decimals to thousandths"), this resource also supports CCSS.MATH.CONTENT.5.NF.A.1. The standard codes can be copied directly into lesson plans, IEP goals, or curriculum maps.

How to Use It in the Classroom

Use as a summative assessment after a unit on fractions and decimals. To use it formatively, observe where students struggle, such as converting fractions without base-ten denominators. Expected completion time is 25-40 minutes. It also works as a pre-assessment for Grade 6 to check retained knowledge.

Who It's For

Designed for fifth-grade math students, the clean layout is accessible for most learners. For students needing support, provide a place value chart. For an extension, have students create a word problem using numbers from the sheet. It pairs well with a fraction-decimal equivalents anchor chart.

Assessing procedural fluency with fractions and decimals is a key indicator of readiness for middle school mathematics. This worksheet provides targeted practice on CCSS.MATH.CONTENT.5.NBT.A.3, requiring students to read, write, and compare decimals and their fractional equivalents. Research from RAND AIRS 2024 highlights the importance of number sense, which is built through flexible manipulation of different number representations. By providing 29 problems that move from simple conversion to application, this resource allows teachers to accurately measure student mastery. The ability to connect abstract decimal values to concrete fractional parts is a foundational skill, and this assessment offers a reliable tool for evaluating that connection in a classroom setting, giving educators actionable data on student performance against a critical Common Core standard.
