I've used this discussion board when working with English Language Learners in activities geared towards discussions. This board helped students use vocabulary learned and practice for the speaking portion of the NYSESLAT, which is the language test in NY.
I've used these boards as an activity when introducing it, as well as an ice breaker/ do now activity after the tool was introduced.
I cut the boards in half and laminated them before use. I printed them using colorful paper for an added effect. These boards have been very popular with 3-6 grade groups.
