Build Words with Endings — Reading -s, -ed, and -ing
A word can change when you add an ending. Add -s to make more than one (cat becomes cats), -ed to tell what already happened (play becomes played), and -ing to tell what is happening now (jump becomes jumping). Read the base word, listen with Hear it, and tap the right ending to build the word. Take your time; there is no timer and no score. Aligned to Common Core RF.1.3.f — reading words with inflectional endings.
