I want to teach my students how to say the past tense -ed forms correctly.
I can find tons of examples but no rules. This is what I've come up with...can you add to it?


If the verbs last sound is:

/k/, /s/, ch, sh, th ....than -ed = /t/

/t/, /d/...than -ed = /id/

everything else -ed= /d/


please help. Thanks!
