Have them quickly tell you their answers, and the first child to answer correctly is the winner. Your child will be able to think harder and exercise his or her ability well knowing that he or she is competing with others.
The basic skill you require in order to successfully assist your child with its 3rd grade math worksheets problems is to be able to identify the difficulty. Does it lack the requisite skills that it should have already possessed for the work at hand? If that is the case then it is best that you take the child back to the missing link, so that your it learns what it is missing and move forward.
Using some games in teaching math enable students to plan their strategies and moves. When they play, they tend to think of their moves which can be a very good exercise using their minds. They will also be able to use their knowledge of mathematics in winning the game. Playing also can help them cooperate with their classmates and helping them also to prepare for the real life situations.
However, get back to your child afterward to find out how far it has gone - math can be very frustrating, especially if the child lacks a strong foundation in the topic it is working on.
