Learning Objectives

Students will be able to understand that some consonants have two sounds and will be able to read words with the consonants “G” and “C” that use both hard and soft sounds.


(5 minutes)
  • Gather students to the rug for the start of the lesson.
  • Ask students to name the 5 vowels, A, E, I, O, and U. Ask them what makes vowels special. Answers might include, "Each letter makes two sounds," or "Vowels are sometimes silent within a word."
  • Say, “Today we are going to learn about some special consonants that also make two sounds. The letters C and G.
  • Both the C and the G make a hard sound, like the /g/ sound in the word “goat” or the /c/ sound, like in the word “cup” and a soft sound, like the /j/ sound you hear in the word “germ” or the /s/ sound you hear in the word “city.”
  • Tell them that here is a handy trick to figuring out if the letter will be using its soft or hard sound. Look at the word and if the letter after the c or g is an i, e, or y, then the g or c will most likely make the soft sound. If the letter after the g or c is any other letter, it will most likely make the hard sound. The hard sound is more common for both the c and the g.
