If you have any comments or problems on this workbook, please email them to fho1928@gmail.com. We have seen that many students did their homework but still could not get A mark consistently. One of the problems is that even though they did their homework or assignments, but the problems given in quizzes or tests by their day school teachers are different from what they did in their homework. Some students also need more practice or tests, and there are not enough test problems in their textbooks. Often it because some students could use a quick review to boost their marks. This workbook was not written just for reviewing, testing, or assessing purposes. Students can also use it to learn new concepts and get ahead. It is challenging to produce a workbook to be used worldwide by instructors all over the world. This workbook can be used worldwide to meet the needs of students with advanced abilities in many countries. How did we produce such a workbook? We have combed through many math books produced by many countries and areas, including China, the USA, Canada, Hong Kong, Taiwan, Singapore etc., to compare their contents and studied their exam papers. We also studied many math problems in the IB program, SSAT math part, and regional and international math assessments. Doing these researches allows us to produce some problems that have a very high standard and some average problems for beginner's level. All drawings in this workbook may not represent the exact scales. This workbook can be used for lower and middle grades.
