The Decimal Place Value – the system by which we name numbers.
One of the least understood topics.
Children who have problem with operations?
Children who have problems with Algebra?
Children who have problems with Calculus?
Often it is because they don't understand the Decimal Place Value System!
The concepts of numbers, and how they work, can be tricky. The Decimal Place Value System is not a trivial one! It took mathematicians many centuries to get it right, especially because the concept of Zero had to be understood well before the system could work well.
This book explains ALL of it in a simple VERY EASY way.
After less than an hour my 6 years old daughter could name or write if told numbers in the Quadrillions (How many know it is a number with 19-21 digits?).
Each lesson has charts to illustrate the ideas and is followed by a worksheet.
If a student has problems with Operations (most pronounced in long division), Decimal Fractions, variables in Algebra, or Calculus, it is recommended that they first study the Decimal Place Value book. How we think about variables is strongly affected by how we think about numbers, a connection not made, understood, discussed, or treated in the education system.
