Learning opportunities include:
1. Make your own Osterstrauss. See how to blow out eggs here. Decorate using Sharpies or paint or be as creative as you like.
2. Research Easter or Spring traditions across the world.
3. I bet your family has it's own traditions. Not just how you celebrate feasts and festivals but how you mark certain other days (e.g. do you have any special rituals when you go back to school after the summer - apart from maybe having a bath? Or what about bedtime rituals? Do you have a special movie night? Or is there some way that you always kick off the holidays or mark a birthday?) Have a chat with your family, figure out all the little traditions that you have and make a book or slideshow about them.
