Can the district provide a workshop day for converting files, since we need Flash?
Flash embedded files/software will no longer be supported. Adobe, the maker of Flash, ended its support this year. It will no longer be supported on any current or future devices. Alternatives can be found in some cases. If you used dice (Flash enabled), there are web pages that have these types of dice. If you used a countdown timer that was Flash, there are web pages out there for that. Not all Flash content has an alternate finding on web pages, but maybe a different type of presentation can be delived for delivery of that content.
