This is an activity I use in my classroom to help my students identify digraphs (wh, sh, ch, th). There are 28 different picture cards, 28 word cards, 4 sorting mats, and 2 different kinds of recording sheets. I would recommending printing on cardstock, laminating the picture and word cards, and sorting mats. This aligns with the CCSS RF.1.3 I can sort digraphs or words with digraphs.
