What This Standard Means
What Students Need to Do
- Students say the sounds shown by the letters in a short word, then blend those sounds together. They use known consonants, vowels, digraphs, and blends to read the word.
What Mastery Looks Like
- A student reads unfamiliar words such as cat, shop, and flag by blending their sounds. The student reads the whole word without guessing from pictures or context.
Common Misconceptions
- Students may say each sound correctly but fail to blend them into a word. They may guess from the first letter or confuse short vowel sounds.
How to Assess It
- Give an exit ticket with five words: map, fish, stop, nest, and cup. Ask each student to read them aloud without picture clues.

Ways to Teach It
Use magnetic letters to build map, change one letter to make mop, then top, and have students read each word aloud.
Ask students to explain how they would read the word sit, naming the sounds and showing how they blend them.
Play word card bingo using words such as sun, bed, fish, clap, and nest, with students reading each called word.
Give students simple classroom labels, such as desk, clock, and shelf, and have them read and match each label to the object.
