Hearing letter sounds is a major key to learning to write and understand English. It can be confusing because many letters or letter combinations have more than one sound. Today I will go over one of the combinations – the suffix –ed.
The suffix –ed is used to represent past tense; plenty of even smaller children may realize this. What a person may not have given attention to is that –ed makes three different sounds.
A sentence to represent this (and practice) is: He rented a boat, jumped in and sailed off.
Hear it? Rented — /ed/ (said like the name, Ed)
Jumped — /t/ (sounds like the sound of a “t”)
Sailed — /d/ (Sounds like a “d”)
Below are examples of words that have the three different sounds. It is good to dictate the words to students, have them write what you are saying, and be sure to have student read back what has been written.
-ed = /ed/ This sound comes after a t or d
Examples: melted, twisted, planted, rented, mended, printed, rusted, acted, blasted, sanded, punted, salted.
-ed = /d/
Examples: grilled, banged, smiled, saved, shelled, drilled, spilled, yelled, changed, filmed, ganged
-ed = /t/
Examples: masked, jumped, fished, skipped, asked, camped, blocked, checked, kicked, dumped, honked, limped
More Advanced words: rowed (d), slipped (t), scrapped (t), smelled (d), stepped (t), snowed (d), turned (d), filled (d)
In class, we had a “bank” of words at the top of a worksheet and a “grid” under the word bank. At the top of the grid were the –ed sounds. We were asked to put the words under the correct –ed sound. After we completed the assignment, we went over each word and the sound they made in class, as a discussion. You may be surprised at how people hear sounds differently!
For Example (our worksheet had many more):
Melted Grilled Jumped punted limped filmed
|-ed = /ed/||-ed = /d/||-ed = /t/|
