A lot of students struggle with ed endings for past tense verbs in English. The pronunciation is different depending on the word. I live in Spain, and Spaniards speaking English often want to just pronounce it phonetically since they are used to doing that in Spanish. For exampled, they might pronounce closed "close-ed" when it's actually pronounced "close-d."
One of my students on here really wants to practice them, so I found him this resource. I love that there is audio for each word. So if you struggle with pronouncing ed words correctly, this might help you!
