Ever had a student with appropriate articulation development, but poor intelligibility? It may be that the student is mumbling or using poor diction due to weak muscles and/or poor diction. This calendar is designed to give students one skill per day to help increase muscle strength and effective use of the articulators. This is a great tool to use as part of Response to Intervention as well. NOTE: There is an easier version created for students age preschool, Kindergarten and First grade.
