Book 5

Know about Zero

There are no specific home activities for this book.

In this relatively short book, the children are taught two key things.

Firstly, when we add or subtract 0 the starting number remains unchanged.

Secondly, when we subtract any number from itself we are always left with zero. In doing so the book addresses the common misconception that 2+0=0 or 2-0=0 where a child thinks incorrectly that adding or subtracting 0 "gets rid" of what you had before.
