Mathematics, or more colloquially, "math", is one of the most important subjects that students learn in school. Not only do good mathematical skills form a necessary for understanding of other subjects, especially the sciences, but also, math is an important life skill.
In all these areas, but especially during the learning of arithmetic, practise and rehearsal is one of the most ways for students to improve their mastery of the topic.
When learning arithmetic, repeatedly doing sums for a long period, with little variation, can soon get boring for many students. Before long, their attention can start to wonder, and as we all know - this is not conducive to learning.
Always be on the look out for tears of frustration, so as to all the child some break. No one learns well enough when confused. At this point both concentration and effective learning are lost. But if you are sure that the tears are merely excuses to skip the homework, pretend to abandon him with the worksheets and let him sweat it out!
