The study compared the efficiency of decimal and sexagesimal, or normal, time systems in the solution of addition problems, using the time required to reach a solution and the number of errors as dependent variables. Twelve subjects solved sets of addition problems composed of 8, 16, or 24 digits, using the decimal and sexagesimal time systems. When the conversion process required by the sexagesimal system was included in the analysis, the results clearly showed that addition using the sexagesimal system required significantly more time (1 1/2 to 2 1/2 times as much) and produced significantly more errors (1 1/2 to 3 times as many). When the conversion process required by the sexagesimal system was excluded from the analysis, there was no significant difference between the two time systems on either dependent variable. (Author).
This book contains over 5000 single-digit addition facts for repeated practice, which is essential for achieving greater speed, instant recall, and retention for long periods of time. Questions are specifically designed to master the easiest ones first, hence building a child's confidence. More challenging addition combinations are more frequent in this book so that they are automatically registered in a student's long-term memory. Each chapter contains several similar timed lessons so that performance can be measured on an ongoing basis. Includes an easier method that avoids carrying over even when carrying over is required, resulting in fewer mistakes. It contains a lot more numbers and less language - there's no fluff, no stories, and no discovery math or creative strategies - just the facts please. The real stuff that is required in higher grades, colleges, universities, and the workplace. If your child is weak in Math, then achieving proficiency in the basics is the best place to start. Every student can become smart at math - no one is born with it. All it takes is repeated practice of the basics. Since math is cumulative, there's simply no point in going any further without complete mastery of single-digit addition. This book has been prepared as a result of much research, and its author studied Mathematics and Statistics for four years (B.Sc.). The public education system has been failing a huge percentage of our students, and it's about time to take some responsibility of our children's education ourselves. Teachers have a lot of material to cover in each grade, and they cannot afford to slow down to help several students with the basics - the material they should have learned in the previous grades. Therefore, a focus on the basics will boost your child's confidence, which is absolutely essential for tackling bigger and more challenging math problems.
