To begin the lesson on '-an', you might say,
Today we are going to start learning about glued sounds. Glued sounds are tricky because they are made up of more than one sound but it is hard to pull those sounds apart. The vowel does not say its normal sound in a glued sound. That’s why we learn these sounds as chunks.
Show students the flash card with the keyword picture card for '-an'. Point to the picture of the van on the card. Say,
This is a van. I hear /v/, /an/. We know the sounds for 'a' and 'n', but when they come together, the 'n' doesn’t let the 'a' say its true short sound. So, when we see 'a', 'n', we are going to say /an/.
Show students that when they see the flash card with the keyword picture, they will say the letter names, then keyword picture, then the sound. Like this: 'a', 'n', van, /an/. Have students repeat, 'a', 'n', van, /an/.
Then show students the flash card with just the letters 'an'. Tell them that when they see that card they are just going to say /an/.
Next, you’ll use your letter flash cards without pictures to play with words that have glued sounds.
Put down the 'an' card. Have students say /an/. Next, place the 'c' in front of the 'an' card. Have students say the sounds /c/, /an/ and then say the word can.
