Teachers should undoubtedly distribute work such as solving crosswords to their students. We are no strangers to the fact that solving Sudoku is considered good for sharpening one's mathematical aptitude, crosswords ammelierate the vocabulary of a person and riddles shrpen the quantitive and qualatative reasoning. I also ensures that students devote some of their time to meaningful things rather thn just whiling it away. The good effet of these mental exercies are not visible all of a sudden but with time one can notice a change, a change for the good obvously. Such teasers also lead to increase in brain synapses increasing the mental health of a person. I wouls thus conclude saying that teachers should give out busy work.
