About this worksheet
Sound buttons open this 3-page 1st grade phonics sheet on the consonant digraphs sh, ch, th and wh. Students mark dots and dashes under ship, when, math and chat. Next they fill the missing digraph in four picture words: shed, duck, bath and chin. The letter box also offers ck, which students need for duck. A final sentence, "Chip hid in the shed.", is read aloud and copied. The practice fits Common Core RF.1.3a and RF.1.3b, and the answer key shows where each dot and dash goes.
