CCSS.ELA-Literacy.RF.1.3f

ELA1st GradePhonics and Word Recognition

The Standard

Read words with inflectional endings.

Common Core State Standards for English Language Arts

What This Standard Means

Students need to read base words with endings like -s, -ed, and -ing. They should see that the ending changes how the word sounds and what it means, while the base word often stays recognizable.

Mastery looks like reading words such as jumping, played, dogs, and boxes without guessing from the first letter. Students often get stuck when the spelling changes, as in make to making, or when -ed has different sounds in jumped, played, and wanted.

Ways to Teach It

  • Give students base word cards and ending cards, then have them build, read, and sort words like play, playing, plays, and played.
  • Ask students to write one sentence using a word ending in -ing and one using a word ending in -ed.
  • Show five words with endings, then have students read each word aloud and circle the base word.
  • Use a class schedule and ask students to read action words like walking, reading, played, and cleans from daily routines.
