Remembrance Day

We have been discussing many different things about Remembrance Day. We read books, watched videos, wrote our wishes for peace and talked about war and Canadian soldiers. We all agreed that no matter what the time period, our Canadian soldiers must have been scared to leave home. They must have missed their families, but were proud to serve our country. We paid tribute to them today in our assembly. We will remember them.
