What's Inside

This single-page PDF has a simple chart. Students rewrite 10 root words after adding the suffixes "-ing" and "-ed." It covers two key spelling rules: doubling the final consonant for CVC words and dropping the silent 'e'. The clean layout provides ample writing space and minimizes distractions, helping students focus on the task of applying these essential spelling patterns correctly.

A Zero-Prep Workflow

This resource is built for efficiency. 1. Print: A single, printer-friendly page for your class (1 min). 2. Distribute: Hand out for immediate use as morning work or a station activity (1 min). 3. Review: Go over answers as a group or collect for a quick check. The focused task makes review fast. Total prep time is under two minutes, making this worksheet a perfect, reliable option for substitute plans.

Standards Alignment

This worksheet directly supports CCSS.ELA-LITERACY.L.3.2.f, which requires students to "Use spelling patterns and generalizations... in writing words." By practicing how to correctly add suffixes, students build the foundational spelling knowledge necessary for proficient writing. The standard code can be copied directly into lesson plans, IEP goals, or curriculum maps to document standards-based instruction.

How to Use It

Use this sheet as a pre-assessment, for guided practice, as independent work, or for homework. It quickly reveals which students understand the suffix rules. For a formative assessment tip, note whether students struggle more with consonant-doubling or the silent 'e' rule; use that data to form small reteaching groups. Most students will complete the worksheet in 10-15 minutes.

Who It's For

Designed for third graders, this sheet also helps fourth graders who need review or advanced second graders. Its clear format supports all learners, including English Language Learners. To provide extra support, pair this worksheet with an anchor chart that explicitly states the spelling rules for adding -ing and -ed. It is beneficial for any student working on conventional spelling patterns.

This resource provides focused practice on applying spelling generalizations, a key component of literacy acquisition as outlined in standard CCSS.ELA-LITERACY.L.3.2.f. By manipulating root words to add inflected endings, students engage in orthographic mapping, strengthening the mental process of storing words for automatic retrieval. Research shows explicit instruction in spelling patterns is more effective than rote memorization. According to Fisher & Frey (2014), practice with morphological units is a critical part of balanced literacy. This worksheet offers that, giving students 20 chances to apply rules for CVC and silent 'e' words. This builds spelling automaticity, freeing cognitive resources for complex writing tasks and contributing to reading fluency.
