Teachers and reading specialists have guided us to say the letter sound before the word for your children to hear the initial letter sound starting the word. Our only exception is the using the word fox with the letter x, because the x in fox accurately makes the (ks – sound). Actively participating in this song daily will help your class achieve the Common Core and national standard of learning one to one letter sound correspondence.
KS Early Learning Standard: Communications and Literacy Foundational Skills(CL.F.p4.3a)-Demonstrates basic knowledge of letter-sound correspondence by producing the sound of some letters. The student chooses an item from the bag and pounds the peg with that beginning sound. The student then produces that sound. I would use this during small group instruction. You could monitor,evaluate and assess students' skills.
