Age at which 85% of Goldman Fristoe Test of Articulation (GFTA-2) Standardization Sample Correctly Produced the Consonant and Consonant Cluster Sounds
Voiceless ‘th’ = sounds like “bathroom”
Voiced ‘th’= sounds like “bathing”
Here's a link to another speech developmental chart: Cambridgeshire Speech Sound Development Chart.
Parents can help expose their children to the early speech sounds while they play with them, during reading time, and by being good models of correct sound production. Another fun way to help to encourage imitation of speech sounds is to get music involved. Here is an example of a music c.d. which has songs for learning early speech sounds: Songs for teaching.
Another component that I use to help with the production of sounds is the use of visual phonics. I use the See-the-Sound system. See-the-Sound Visual Phonics is a system of sound associations which represent each sound in our language with a hand signal and a graphic or written symbol. In See-the-Sound Visual Phonics the 46 hand signals represent sounds, not letters or words. Follow this link: Visual Phonics for more information and to see a video clip of someone using the system for spelling the word CAT.
P.S. I also think that this would be a wonderful packet for helping to increase early letter awareness and phonics, as each letter is worked on individually. It would be a great early literacy packet for the preschool crowd!
I hope that you find every page useful and fun to do with your students!
