Which will Mr. Hylton most likely assess initially?

While spelling and grammar are important aspects of language development, they are not the primary focus during the initial assessment of the lesson. At this stage, the emphasis is on understanding sounds rather than the correct spelling or grammatical structure of words.

Assessing academic vocabulary is typically conducted later in the learning process when students are more familiar with the sounds and structures of words. In this case, Mr. Hylton's immediate goal is to help students connect the trigraph "tch" with its corresponding sound, rather than introducing or evaluating vocabulary.

While letter-sound correspondence is indeed a critical area of focus in phonics instruction, the question specifically asks what Mr. Hylton will assess initially. He is likely to first gauge students' understanding of the /ch/ sound produced by the trigraph "tch" before moving on to broader topics like letter-sound correspondence.
