Once children learn to blend sounds in word families, they can proceed to decode words a sound at a time, such as /d/-/o/-/g/ to sound out and then blend dog.
This is another activity I made for my friend’s daughter, using clothespins on an ice-cream stick.
To blend the individual sounds, move each peg with the first sound (e.g /s/) to the left. While doing that, sound the letter.
Move the rest of the letters (/i/ and /t/ and blend the sounds to read the word (sit).
