Here is a free look at what my product "Ask 3 Before Me" bundle looks like. In the bundle there is also a hall pass. Great to use laminated with string or in a plastic covered lanyard.
Ask 3 Before Me is a great tool to use during centres or independent learning. This allows the teacher to work uninterrupted with a group of students while there is someone to answer questions (or being the volunteer expert) during the exploration/work period.
