Here's a lovely art project that makes a super outdoor display that I like because it's so doable by one teacher with a large class of children. Hanging from an aspen tree in The Coombes School playground were lots of wooden spoons.
The children had to make their wooden spoon into a character of their choice. First they had to design the clothes and faces. If you notice the drawings are the same size as the spoons!
The children then used a variety of different materials, pens and wool to create their characters. Here's some of the results...
I liked the combination of the paper ideas and the wooden spoons displayed outside together.
Finally, the children in Years 1 & 2 came outside to write a story about their wooden spoon characters.
I can see so much potential in this activity. The wooden spoons would link beautifully into a historical project or to illustrate a story, which can then be re-told through a wooden spoon puppet show. If you have few or no trees but have lots of fences instead, then you might find my campaign to give ugly fences a makeover useful for more ideas about 3D displays.
