A series of worksheets for the BBC micro:bit. Each has a task brief, suggested blocks to use and some extension suggestions. Each has been given a nominal difficulty level (based on my judgment).
The idea is not to give step-by-step instructions but present a set of relevant 'Lego blocks' to put together in the correct order. The blocks appear on the sheet approximately in order, but pupils will need to think about the order and may need to edit specific text or values. Where similar blocks are needed (such as strings for 'win' and 'lose'), they may only be shown once.
'Solutions 1' is a set of screenshots of my ideas on how to meet the briefs. It is not comprehensive; in particular, few of the more 'basic' solutions are shown. The solutions may not all be optimal. It is called 'Solutions 1' in the optimistic reckoning that more challenges may yet come!
Example-solutions.doc is NOT a document file. It is actually a Zip of tokenised files for working versions of the worksheets which can be loaded into the BBC's online editor. (To use, download the file and change the extension from DOC to ZIP.) Do bear in mind that there may be more efficient ways to achieve the same result (not least by converting from the Block Editor to Touch Develop). This is something that bright pupils might want to investigate, especially for harder tasks or to change how long images/text display on screen.
