+-×÷ boys and girls come out to play

the school I am working in at the moment

is surrounded by a big imposing

chain link fence:

very unwelcoming:

so I thought it would be fun to create some kind of

'graffiti'  that the head would approve of:

we decided to weave playground chants:

teddy bear, teddy bear, turn around:

bumper car, bumper car:

england, ireland, scotland, wales:

the plan was good:

but the yellow wool was too thin:

we need coloured string:

anyone got some?
