Note to parents and teachers
This chapter introduces the concept of positive and
negative numbers. We will simply refer to them as plus
and minus numbers throughout the book.
These methods make positive and negative numbers
tangible. Children can easily relate to the concept because
it is made visual.
Calculating numbers in the eighties using double
multiplication develops concentration. I fi nd most children
can do the calculations much more easily than most adults
think they should be able to.
Kids love showing off. Give them the opportunity.
