The first hard Grade 1 sheet mixes all four digraphs (sh, ch, th, wh) with tricky blend distractors like sp, sl, cl, and cr. Four multiple-choice items force first graders to tell digraphs (one sound) apart from blends (two sounds). Five fill-in sentences span dish, chin, down, bath, and what, testing both initial and final positions. One trick item uses a non-digraph word (down) so children practice spotting when a word does NOT start with a digraph.
