Researchers Manyak, VonGunten, Autenrieth, Gillis, Baumann, & Blachowicz (2014) state that students need "multiple opportunities to develop deeper understanding of the word meanings" and instruction should target word meanings with visual images. Word sketches do just that. They allow students to create their own visual representations of word meanings. This can be done individually or in small teams. No more dictionary worksheets!
