Factor by Grouping Short-cut
... Even + even or odd + odd. Since the 3 and 63 are both odd, you must find two odd factors. 3 * 63 = 3 * 9 * 7 = 3 * 3 * 3 * 7. List all possible odd factors. Remember odd * odd = odd. 3 * ____, 7 * _____, 9 * _____, 21 * _____, 27 * ____, and 63 * ____. It appears that we may have many possible group ...

Mental Calculation Methods - St Edmund`s RC Primary School
... When using a jotting, there is no requirement to follow a particular method of recording. A feature of mental calculation is that a type of calculation can often be worked out in several different ways. Which method is best will depend on the numbers involved, the age of the children and the range o ...
