9 and 10 year olds. (Year 5/6)
This lesson grew from the need to keep the children challenged but engaged, as it is week 11 and the children are starting to show signs of exhaustion.
They had worked with complimentary colours before, so that was easy for them to handle. The tricky part was reassembling their pictures in order.
They drew 'The Three Billy Goats Gruff' in black crayon, after listening to the fairy tale. They held their drawing up to the window and copied it. One picture was coloured with primary and secondary colours. The second drawing was coloured with the complimentary colours of the first. For example, the blue sky was orange in the second picture.
The children prepared a cardboard concertina.
The pictures were cut into even strips. They reassembled each picture and swapped every second sprig, for a complimentary one. These were stuck onto the concertina. Both sides had the image, so we put a little hole and a string in the top/middle, so the concertina could rotate.
