This resource was designed for occasional use when researching the meaning of new terms. Typing in part of a word shows a list of where else that fragment of a word is used and what it means.

This resource was designed to provide searchable curated links to online resources, with a visual indicator of their relevance and suitability. 

The workload in maintaining this meant it was never implemented, but it could be readily adapted for other purposes, with a narrower scope. 

Resources you add can be password protected.
I've used it here to add a whole class quiz game.

Interactive powerpoint diagrams. This is activity is in the form of a quiz. As students give the correct answer they can then choose the colour for an appropriate section of the diagram. Labels and explanatory text then appear on the diagram for that question.

Teachers can edit the questions, diagram labels and colour options. 

Visual basic is used to power this activity - so it has to be run locally, it can't be used online.  An online equivalent using Google apps script with Google slides may be development at some point in the future.
