Which of the following activities best develops students' knowledge of consonant digraphs?

• A. Searching books in the library and writing down words found that begin with str-, spr-, and chr-
• B. Sorting pictures of words beginning with wh-, th-, and sh- according to their sounds
• C. Reading the room to find words and items that begin with br-, cr-, and tr-
• D. Writing and sharing stories using words beginning with sh-, str-, and fr-

Answer: (B)

Consonant digraphs are two-letter sequences that represent a single sound, such as wh, th, and sh. An activity that asks students to sort pictures of words beginning with these digraphs by their sounds directly builds phonemic awareness and the connection between oral sounds and written cues. By hearing the initial sound and grouping words accordingly, students reinforce that these two-letter sequences function as units in telling apart different sounds and spellings, which is essential for decoding and early spelling development.

The other options involve working with word onsets that are blends or clusters (like str-, spr-, chr-, br-, cr-, tr-, fr-), or they mix writing with broader reading tasks. While those activities can support literacy skills in other ways, they don’t target recognizing and sorting words by specific consonant digraph sounds as clearly or directly as a picture-sorting task focused on wh-, th-, and sh-. This makes the sorting activity the most effective choice for developing knowledge of consonant digraphs.
