Asking for help

My students often require assistance but don't ask for help.
This is very frustrating to me as a speech therapist. I need them to be able to verbalize when they need more help. Someone will not always be there to read their facial expressions or notice that they haven't written anything.
Other students have auditory processing difficulties and need things repeated several times. Whatever the case, these kids need to ask for help.

I have included a color set and a black and white set.
