Children are playing in the playground and then they come in to class. Teacher says to the first child "Hello Becky, what have you been doing this playtime?" Becky replies "I have been playing in the sand box". "Very good" says the teacher. "If you can spell "sand" on the blackboard, I will give you a biscuit". Becky duly goes and writes "sand" on the blackboard. Teacher then says "Hello Freddie, and what have you been doing in your playtime Freddie replies "Playing with Becky in the sand box". "Very good" says the teacher. "If you can spell "box" on the blackboard, I will give you a biscuit". Freddie duly goes and writes "box" on the blackboard. Teacher then says "Hello Mohammed. Have you been playing in the sand box with Becky and Freddie?" "No" replies Mohammed., "I wanted to, but they would not let me. Every time I went near them they started throwing stones at me". "Oh dear" said the teacher. "That sounds like blatant racial discrimination. I tell you what, if you can spell blatant racial discrimination I will give you a biscuit".
