Unfortunately, the short vowel sounds are tough for the little ones to remember. The difference between the short e and the short i are pretty miniscule, but essential for encoding and decoding words.
I'm one who needs to get the kids moving. I have all sorts of little tricks for the children to do to help them remember certain things, including vowel sounds.
When we practice short a, the children turn their body into an A shape, then "take off" saying ăăăăstronaut.
The key word for the short i sound is insect. The kids are always very creative hopping around the room as the letter I, saying ĭ ĭ ĭnsect!You guessed it, short o's key word is octopus. Can you picture the little ones running around saying ŏŏŏctoopus? There's lots of giggling involved.
I'm combining many of the ways that research shows brains remember: Getting involved physically, combining the physical with the auditory, and, of course, making it fun. It takes some practice, but the little ones learn to identify those 5 sounds with those 5 letters.
Enjoy these brainy vowel sounds!
