About this resource

Description

This ED suffix worksheet helps third graders master one of the trickiest spelling rules in English: when a short word ends in one vowel and one consonant, you double that final consonant before adding the suffix ed. Knowing when to double, and when not to, turns past tense verbs from a guessing game into a rule students can check for themselves.

About This Worksheet

The page opens with the rule and a worked example, nap + p + ed = napped. In the first section, students look at eight verbs, decide whether each one doubles its last consonant, and then write the past tense. Half of the words follow the doubling rule and half do not, so students must really look at how each word ends. Next, they complete five sentences by writing the past tense of a bold verb. Finally, they explain in their own words why the word jump does not double. Use it as guided practice after a mini lesson, as independent seat work, or as a quick spelling check.

What’s Included

  • 1 printable 3rd grade suffixes worksheet on the ed doubling rule
  • 8 decide-and-write past tense verbs
  • 5 sentence completion items
  • 1 short written explanation prompt
  • A complete answer key

Why It Helps Kids

First, it builds a spelling habit: students learn to check the end of a word before they add a suffix. Second, mixing doubling words with words like melt and rain stops students from doubling every consonant they see. Third, writing each new verb inside a sentence connects spelling to meaning and grammar, which makes the rule stick.

Ideas for Teachers and Parents

Have students highlight the last three letters of each word in the first section before they write. Turn the sentence section into a quick oral warm-up, then let children write their own sentences with the leftover words. Pair this ED suffix worksheet with a word sort where students group verbs into double and just add ed piles, or send it home as spelling homework with the answer key for families.
