What This Standard Means
What Students Need to Do
- Students identify a familiar root word inside related forms such as looks, looked, and looking. They use the shared root and changing endings to understand how the words are connected.
What Mastery Looks Like
- A student can group common inflected forms under the correct root. The student explains what stays the same in meaning and what the ending changes.
Common Misconceptions
- Students may treat every changed ending as a completely new word. They may remove letters that belong to the root or call the ending the root.
How to Assess It
- Give students play, plays, played, and playing. Ask them to mark the root, identify each ending, and explain how the forms are related.

Play Root Family Sort by grouping mixed inflected forms beneath their shared root words.
Collect action words from a class schedule and create past, present, or ongoing forms for each.
