About this worksheet
Twelve words with -s, -ed or -ing endings.
What kids practice
Endings change a word's meaning. -s can mean more than one or tell what someone does (she jumps). -ed tells that it already happened (jumped). -ing tells it is happening now (jumping). Kids learn to find the base word, read it, then add the ending. Endings connect phonics to grammar: kids sound out the base word, then add the ending.
Watch for
- Dropping the ending when reading, like reading jumped as jump.
- Reading -ed as a separate syllable every time, like jump-ed.
- Adding -ed to words that change, like runned. These sheets use regular words only.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full endings -s -ed -ing phonics guide for 1st grade.
