About this resource
Description
This ing suffix worksheet teaches one of the trickiest spelling moves in early grammar: when to double the last consonant before adding ing. A short word that ends in one vowel and one consonant, like swim or chop, doubles its final letter to make swimming and chopping. Words such as rain, rest and paint just add ing. Knowing the difference helps students spell action words correctly every time they write.
About the Worksheet
The page opens with a clear rule line and a worked example, tap + p + ing = tapping. In Part A, students look at eight base verbs, decide whether each one doubles its last consonant, and write the new word. The doubling and non-doubling words are mixed together so students must check every word instead of following a pattern. In Part B, students add ing to a bold verb to complete five everyday sentences. Part C asks them to explain in writing why rain does not double its last letter, which shows they understand the rule and are not just copying it. A matching answer key is included for quick checking.
What’s Included
- A rule reminder with a worked example
- Eight decide-then-write base verbs
- Five sentence completion items
- One written explanation question
- A full answer key
Why It Helps Kids
- Students practice a spelling rule they will use in almost every piece of writing.
- Sorting doubling from non-doubling words builds careful, word-by-word checking.
- Explaining the rule in their own words deepens understanding and memory.
Ideas for Teachers and Parents
Before starting, write a few verbs on the board and have students clap once for each vowel sound, then circle the last two letters to spot the one-vowel, one-consonant pattern. Use this 3rd grade suffix worksheet as a word work center, a quick spelling review, or homework after a grammar lesson. For extra practice, ask students to find five verbs in their reading book and decide whether each one doubles before ing. This ing suffix worksheet also pairs well with a past-tense lesson on adding ed.
