You'll notice that in the Reading Universe continuum, the '-tch' spelling rule is introduced after digraphs and blends. Students need to understand digraphs to recognize the /ch/ sound. Learning digraphs and blends will also open up many more words ending with '-tch'.
The '-ck' and FLoSS(Z) spelling rules also come before '-tch' in the continuum. These rules are more consistent and typically easier for students to apply in their spelling than '-tch'. Learning '-tch' later on in the phonics continuum ensures students have had ample practice making less complex spelling decisions and that they can decode short vowel, one-syllable words.
