This is a six-panel comic designed to target the production of /k/.
It can be read orally for auditory bombardment, or the clinician can instruct the student to repeat each speech bubble after a model is provided.
I've been using it during my preschool speech sessions to elicit productions of /k/, and then I give the parents a copy to read for auditory bombardment at home.
Definitely make sure to emphasize the /k/ sound! Good luck :)
