Common Core State Standards:
RF.K.2.e Add or substitute individual sounds (phonemes) in simple, one-syllable words to make new words.
RF.1.3.b Decode regularly spelled one-syllable words
My kiddos are still having some trouble with changing one letter in a cvc word to make a new word. Even though it is a kindergarten standard, I feel that we need some review with this skill. Hope this helps someone else out there. :) Hugs!
