Use these simple pictures and the great idea of writing the room, to get your firsties to practice spelling CVC and CVCC (-ck) words. The pictures are easy for them to solve and the recording sheet will be easy for you to check. Once they get their wiggles out by walking around the room, and their brains warmed up with the spelling practice, then have everyone sit down and dictate a sentence or two (or 3) to them using additional skills you want them to practice but don't lend themselves to decent pictures. (for example: y or qu as beginning consonant.).
