We talked about it a little in circle time, then later in the day everybody made hina! The 3-4 class glued a pompom onto a cardboard tube to make the head and body. The kimono was made from a semicircle of paper with the corners rounded off, this was fastened round the cardboard tube so it flared out a bit.
The 4-5 class made origami ones (I have an instruction sheet but it's kind of hard to explain without the pictures!!) which were then fixed to a red card.
We also served the little coloured rice-crackers at snack time, and Yuko (the Japanese co-teacher) brought in her own Hina display to show the children.

Edited to add - just found the same origami pattern as we used at the bottom of this page: http://www.tourism.metro.tokyo.jp/en...ring/hina.html
