This is a simple sort to help your students practice that tricky "tr" blend. To allow for differentiation, the sort features 2 sets of cards: one with both words and pictures, and another with just pictures. Each set includes 10 words that begin with "tr" and 10 words that begin with "ch". I've also included a "tr or ch?" sorting mat and a recording sheet.
When I use these cards, I print an extra copy of the sorting mat to cut apart and use as headers for a pocket chart sort. I introduce the sort as a whole class lesson, and later I put it in a literacy center with the recording sheet so that my students can practice pronouncing the "tr" blend properly, as well as reading and spelling words with "tr" and "ch".
