Over the years, students' performances in Numeracy Tests have been very disappointing, ranking among the lowest in passes in National Achievement Tests. Many students also admit that they hate Mathematics because it is too difficult. A Practical Guide to Mastering Numeracy Tests is a series of books organized in different volumes to help students succeed in Mathematics without being overwhelmed by the numerous concepts that they need to master. Each volume deals with several related and interrelated concepts that guide the students gradually towards mastering numeracy concepts up to Grade 6 level and towards being successful in Numeracy Tests; especially the Grade Six National Achievement Test in Mathematics, which is one of the exams offered nationally to evaluate students' readiness for Grade 7 or Form 1 in secondary schools. Volume 1 Number Concepts: In this volume, students are introduced to the understanding of numbers in detail. The book begins with teaching students about the ten basic numerals and the Base-Ten System that shape the building blocks of numbers. Then, it moves along smoothly to the more intricate nature and concepts of numbers, such as Roman Numerals, L.C.M., Square Numbers and Square Root, Factors, Prime Number, H.C.F., Place Value and Value, Ordering Numbers, Rounding-off numbers and other relevant concepts. The topics are presented in a logical and sequential manner with clear explanations and exercises that will allow the students to test their understanding of the concepts taught. Students are presented with a Certificate of Achievement at the end of the volume as a testament to their excellent performance in the given Mastery Tests on Number Concepts and as a motivational tool to encourage them as they move forward towards greater accomplishments and mastery of Numeracy Tests. It is hoped that such success will boost students' confidence in the subject and help them to develop a love for Mathematics.
