Practical Life Tips:
You may like to take your time presenting these food prep activities instead of offering them all in one week.
Making Sushi. If you decide to give authentic experience - I would recommend making sushi together with children in a small group using traditional cooking tools, like a bamboo mat.
However, for an individual activity, you can offer a simplified version.
Cook rice in advance and keep refrigerated if possible.
Cut sushi wraps in four quarters. Invite the child to scoop one teaspoon of rice and spread on sushi wrap.
As an option, offer simple fillings (e.g. carrot and cucumber strips) and sprinkle with sesame seeds. Place fillings in the middle and roll.
Making Tea. Make this process as simple or as complex as you are comfortable with. In our classroom, we used to prepare herbal tea (chamomile, dandelion or mint) before children arrived in the classroom and poured in a teapot ourselves.
From there children invited their friends to join them and served tea from the teapot. In traditional Russian ceremony, children are encouraged to pour tea in a small tea plate and sip from the edge.
When they were imitating the Korean tea ceremony - children took a small mat, spread it on the ground, place a tray with tea and cups, invited a friend to join, sit on their legs and enjoyed a cup of tea together.
Sometimes we put on relaxing Asian music on the background.
Morrocan Salad. Invite the child to peel a mandarine, sprinkle powdered sugar and cinnamon on top. Encourage to share with their friends.
Corn Chips. Offer the child to make a snack corn chips. Invite him or her to grate some cheese and cut lettuce.
