These worksheets are created after a lot of thought and toil and prepared according to the different age levels of the children. They are equipped to cater to a different range of teaching stages. The child can get proficient in dealing with complicated maths problems by solving sums in the worksheets and this can make the basic education engaging and fun.
Who's Fault? Is it his fault that he lacks confidence with word problems? Not entirely. Our actions, as educators, seem to imply a belief that solving word problems should come more naturally than simpler operations like arithmetic and algebra. Many parents and teachers feel justified in encouraging (i.e. forcing) a child to work hundreds or thousands of math worksheets, drill multiplication tables, long division... but few encourage solving hundreds of story problems. One suspects that the relative ease of creating and checking ordinary math worksheets keeps the focus of math education on simple, atomic operations at the expense of more holistic story problems.
