Focusing on a few words per week helps students, especially beginning communicators, who are using AAC, to acquire new vocabulary. Classroom staff, families, (and even SLPs!) need ideas of ways to incorporate it throughout the day. Varying the context and keeping motivation high is absolutely essential. I send these home and out to classroom staff at the beginning of the week to help give ideas. Then I post them around the classroom too and I encourage teachers and program aides to write in their own ideas if they've worked well!
This one is a little lengthier because some feel that "again" and "more" shouldn't be used interchangeably. It depends on the student and where you project there language level to be in the near future. If you predict that they will be forming grammatically correct sentences anytime in the near future, this is important. If acquisition is more slow-going and getting their message across at the word level takes priority, then let "more" serve the function of "again."
