At the beginning of October I followed a link from Veterans Affairs Canada's Facebook page to a page where you can ask them to send you educational materials for kids for Remembrance Day.
Two weeks ago the girls read through Tales of Animals in War, and Take Time to Remember. Then they wrote a postcard to a veteran, and also decorated a card and note for a veteran.
The take time to remember was great for the girls - and would also be wonderful for Sparks.
(Unless you plan on reading Tales of Animals in War, it is too advanced for Brownies. For Guides and Pathfinders it would be wonderful!)
