Fantasy/violence should not be used for learning!

Recently I came across an article regarding a teacher that used racisim and inapproriate violence in oreder to " encourgae" math. The teacher had given thrid graders math problems using things such as " Humans in ovens" " a SWAT team memeber kills hundreds of terrorist". The teacher had said that she was trying to get math exciting for the kids by using what " they like most ". I don't think that this is approriate action to get the children a bit more excited for the subject. Especially for third graders. At this age kids should not be exposed to such violence. The parents were furious and these " math problems" cost the teacher her job.
