Add and Subtract Decimals Notes and Quiz, Grade 5

Help your students gain confidence with decimal operations using this ready-to-use packet for Envision Math Grade 5, Topic 2: Adding and Subtracting Decimals. This resource is designed by a classroom teacher to support both whole-class instruction and independent learning. Even if you do not use the Envision Math curriculum, these materials can be used as a stand-alone unit to teach or review decimal skills.

Inside, you’ll find student notes, teacher notes, a teacher-created quiz, and answer keys. The lessons are structured to break down each skill step by step, making complex concepts more approachable for 5th graders.

Topic 2 Lessons cover:

This packet has been updated for 2025 to include improved formatting, no page numbers (so it works with multiple editions of Envision Math), and increased readability for ADA compliance and screen readers.

Please note: Problem-solving lessons are not included, as they are taught using a separate curriculum.

Each topic is also available individually, giving you the flexibility to select exactly what you need.

This resource is aligned with, but not affiliated with, Envision Math Grade 5. It was created for my own students and has been classroom-tested to ensure it is practical, clear, and effective.
