To celebrate Matariki we made a korowai. All of our toddlers made a collage feather and the teachers made one too, then we put them all together to make our cloak. This korowai is representative of all the children in our room. It was the central part of our wall display on Matariki this year.
Make constellations in a tube. I actually do this a lot when we have a spare tube for my kids and for my former daycare I would take dark construction paper scraps and just put it around roughly flat and use a pin to push in the outline of whatever the kids wanted...Great reward. They love it. Or you can, as I did for the older kids, let them select the constellation and I would punch it in. Great cheap activity to WOW any child.
