This example shows Trello being used for an assessment task, with the lists along the top representing a scale of ability i.e. if the children were solving problems involving patterns then the children could move their card to where they aim to achieve.
It could then be revisited after to assess the completed work. The board could then be reset and reused for the next lesson with a new set of aims. If you have an interactive whiteboard you could leave the Trello board open and have the children move their cards themselves throughout the lesson, as they realise they are able achieve more of the task.
