They are confidently sounding out and spelling CVC words as they write simple sentences

I have been teaching kindergarten for 5 years now. This year at the end of the 2nd trimester, all but one of my 20 students have a firm knowledge of letter recognition (upper and lowercase) and letter sounds. They are confidently sounding out and spelling CVC words as they write simple sentences. Their parents are amazed at how quickly they learned letter sounds and I am gratified at how easily they are applying this knowledge to become emergent readers.
