TWELVE kilometres east of Warwick, the Jumpers and Jazz spirit has a strong presence at Murray's Bridge State School.

The 12 students at the small country school put on their thinking caps last term to prepare this year's tree jumper.

Teacher Melissa Pickering said the children were excited this time of year.

"The kids know Jumpers and Jazz happens every year and they look forward to it,” Mrs Pickering said.

"They love going into town and coming back to school the next day and talk about all the decorations they saw.”

For this year's school theme of green, the school put together a design based on storybook The Very Hungry Caterpillar.

"We wanted all students to be involved, the story is part of our literacy program so all kids know it well and could incorporate ideas,” she said.

Each child from Prep to Year 6 created parts for the tree during arts and craft sessions.

"The children did a lot of colouring for the food and leaf decorations, lots of green used there and we teachers laminated them so they wouldn't be damaged in wet weather,” Mrs Pickering said.

"We also wrapped the tree in wool and used a woolly foam ball for the caterpillar cocoon.

"The caterpillar itself is made out of sewn materials which we stuffed, the children had fun with that.”

Warwick Art Gallery director Karina Devine, who judged the school tree jumper competition, was pleased to see how much decorated trees brightened school grounds.

"The theme was announced in February and we didn't know then we would have such a terrible season so the theme (green) has even more meaning”, she said.

Ms Devine said all schools entered needed to be congratulated on their amazing efforts.

"Students always have ways of expressing the theme that are imaginative and unexpected,” she said.

Mrs Pickering said the school display was a great way to involve kids in the festival.

"For a small school like ours, it's hard sometimes to be involved in big events that happen in Warwick,” she said.

"Jumpers and Jazz and decorating the trees is an achievable task for us, it's something all the students can do and it makes them really happy when they can be a part of something outside of school.”

Decorated trees are at each participating campus and Ms Devine encouraged members of the community to drive out for a look.
