About this worksheet

Inflectional endings change a word's number or time without changing its core meaning. First graders need to connect -s with more than one, -ed with the past, and -ing with an action happening now. The first challenge is choosing the ending that matches the sentence meaning. The next is attaching it accurately, including common changes such as buses, stopped, and making. This worksheet rotates among selecting a suffix, forming a complete word, removing an ending to find the base, and checking a changed spelling. Support items focus on straightforward additions. Standard and challenge practice include doubling, adding ES, changing Y, and dropping silent E, but the purpose remains inflection. Ask your child to name the base word before adding anything. Then read the clue for number or time and inspect the join between the base and ending rather than copying letters automatically.

What your child will learn

  • Choose -s, -ed, or -ing from meaning
  • Attach an ending to a base word
  • Find a base inside an inflected word
  • Apply common spelling changes at the join

Worked example

Jump happened before now, so add -ed to jump and spell jumped.

Common mistake

Choosing an ending by sound alone without checking whether the clue means plural, past, or happening now.

Find the base word, decide number or time, then attach the ending.
