I use these prompts and record keeping techniques to increase my bilingual 4 year old and 5 year old Kindergarten students Oral English Language. In Wisconsin, we measure student performance using WIDA's assessments therefore, my record keeping is based on their speaking rubrics.
I try my best to talk as little as possible, so the students talk more. It can be messy and feel a bit out of control, but it's worth it. I've seen great results!
