Many brave soldiers from the ANZACs as well as from Great Britain and South Africa (and of course from Turkey) fought at Gallipoli. Design an appropriate medal using this outline, and colour it in.
This Remembrance Day or Anzac Day "Lest We Forget" printable has relatively simple lines for cutting out - perhaps for a display on your board - or can be used "as is" for a poster.
This lovely free Remembrance Day colouring page features poppies for remembrance and a banner with the traditional words "Lest we forget". It would also make a good Anzac Day colouring sheet, of course.
