The ending -ed is spelled the same way every time, but it has three sounds. In jumped it sounds like t, in played it sounds like d, and in wanted it sounds like id, with a whole extra syllable. A second grader who reads aloud will usually say the right sound without thinking, but hearing the three sounds on purpose makes spelling easier, because the same letters hide behind all three.
This worksheet gives ten words that end in -ed, and the child says each one aloud and circles the sound that the ending makes. The words are mixed so that the child cannot guess from the pattern. Ask your child to listen for the last sound in the word. If the word gains an extra beat, as in want-ed, the ending is id.
What your child will learn
Hear the three sounds of the ending -ed
Know that -ed adds a beat only after t and d
Say past-tense words aloud correctly
Common Core standard: RF.2.3.D
Worked example
The word is jumped. Say it: jumpt. The -ed sounds like t, so circle t. The word wanted has an extra beat, want-ed, so its ending is id.
Common mistake
Choosing d for every word because the ending is spelled with a d.
Helpful hint
Say the word slowly. Is the end a t, a d, or an extra beat?
