I used to use this an elkonin box like this one:
My children need something more engaging during guided reading groups. So I can up with this one!
Most of the children that I teach need explicit instruction in phonemic awareness. So, at the beginning of the year I give each child 3 chips that they house in the boxes. I say a word such as fish. They repeat by stretching the word and sliding a chip to each circle in the submarine.
For example, fish /f/ /i/ /sh/ Then they place their pointer finger on the dot and blend the sounds together.
I hope you found this helpful. Please let me know if you have any questions. If you like this idea, I have the submarine elkonin box for you to down. Just click on the picture above!
