You will be teaching the CV Rule or the consonant vowel rule. A vowel at the end of a short word usually has a long vowel sound.
You can write the words no, go, me, and we or use magnetic letters to make the words NO, GO, ME, and WE.
The first step is to show a child to make the letter sounds and blend the sounds together to make the sounds into a word.
Here's a video of me showing how to blend the sounds in the words NO, GO, and SO using magnetic letters.
Magnetic letters have the added bonus of mixing the letters up and asking a child to put them back together.
You can share read the book Hop on Pop by Dr. Suess to allow a child to practice the words WE, ME, HE, and NO. You will read the book to a child. Pause and point under WE, HE, ME, and NO at the beginning of sentences and when they are written in bold type at the top of the page. Make sure your child knows which words he or she is expected to read. Some children want to take over all the reading in a shared reading and get frustrated.
Here are the pages from Hop on Pop you can share read.
