How to run it

Point at the helping verb. Is, are and am signal -ing, and their absence signals the past — a student who learns to look there will sort correctly without thinking about the ending at all. Once sorting is reliable, give a bare verb and a time word and ask for the sentence, which is production rather than recognition. Eight minutes covers the twelve.

Cueing ladder

Start at the top. Add support one step at a time.

  1. Step 1IndependentPresent the item and wait 5 seconds of quiet before helping.Log as correct
  2. Step 2HintStress the part of the sentence that changes, or point to the word ending.Log as cued
  3. Step 3Sentence starterSay the first half of the sentence and let the student finish it.Log as cued
  4. Step 4ModelSay the correct form in the whole sentence; the student repeats it.Log as cued

Adjust it

Easier

Give a sentence starter every time, and do fewer cards.

Harder

Ask for a new sentence of the student's own with the same form, with no card to lean on.

Matching IEP goal

Given sentence cards, Student will produce the target grammatical form in sentences in 8 of 10 opportunities across 3 consecutive sessions, given no more than an indirect cue.

About this activity

Twelve sentences sorted by which ending they use: She is jumping, They are playing, The dog is barking, Mom is cooking, The baby is crying and They are running take -ing; He walked home, We painted the fence, I cleaned my room, She washed the dishes, He wanted a snack and We watched a movie take -ed. The helping verb is the real clue, which is what makes this a syntax task as much as a morphology one.

What to listen for

Listen for the -ed pronunciations. Walked ends in a /t/ sound, cleaned in a /d/, and wanted adds a whole syllable — three different endings from one spelling, and students who have been taught -ed as one thing find this confusing rather than obvious. Watch for the helping verb being omitted in speech, which is a separate and common pattern.

Carrying it home

Narrating what is happening and what happened gives both forms constantly. I'm cooking, then I cooked dinner — the pair heard together is what makes the contrast audible.

Questions

What grades is this for?
First through third, as early morphology and verb tense work.
Is it free?
Yes, all twelve sentences play with no account.
Why does -ed sound different in different words?
The ending assimilates to the sound before it — washed ends in a /t/ sound, cleaned in a /d/, wanted adds a syllable. One spelling, three pronunciations, and saying so directly clears up a lot of confusion.
