Strategy: er, ir, ur is a short video from Nessy that teaches students about spelling words with the letter, after the vowels “e”, “i”, and “u”. The letter “r” will change the sound of the vowels to /û/. Combined with “r”, it makes the sounds found in the words: term, fir, and turn.
I like the approach that Nessy has taken, because they explain the rule with a short, memorable, visual story, with supportive, brightly colored text added below. These videos from Nessy are created with dyslexic students in mind, but are truly valuable for most, if not all people.
