Add a beginning consonant sound to the word at to read the three-sound words cat, sat, and mat.
Big day. Last week you read at. This week you add one more sound to the front and build a whole new word. Add c to the front of at: cat!
Try it again. Add s to at: sat. Add m to at: mat. One new sound at the front changes the whole word. These are your very first real, three-sound words.
Mastery looks like: They read cat, sat, and mat by blending a beginning sound onto the known ending at, in any order, without hints.
Common stumbles: Reading only the at part and skipping the new beginning sound; needing the words in the same order every time instead of reading each one on its own.
