Spot the Difference for Articulation I developed this activity to target articulation at the conversation level. There is a sheet for the following sounds: p, b, t, d, k, g, f, v, s, z, s blends, prevocalic r, vocalic r, r blends, l, l blends, sh, ch, j, and th. As students explain the differences between the pictures, they will produce their target sound in various word positions. There are ten differences per sheet. Please note that these are intentionally designed to be easy for younger child
