The series of Abacus & Mental Arithmetic Books
BOOK 1 introduces the basic knowledge of using an abacus and introduces basic rules for carryover in one digit addition.
BOOK 2 introduces all the rules for carryover and two digits addition and subtraction on abacus.
BOOK 3 helps students to review all the rules for carryover on abacus and addition and subtraction within 100.
BOOK 4 helps students to review all the rules for carryover on abacus and addition and subtraction over 100.
BOOK 5 helps students to train addition and subtraction within ten thousand and decimals units, and also multiplication and division.
Don't worry! You can find the instructions of how to use the book and the abacus. The books are designed for beginners. Illustrations are provided to demonstrate how to move the beads and when to apply the abacus rules for the arithmetic problems.
The operation on the abacus may be a little bit hard for young learners to understand. Our books use illustrations and stories to help young learners to understand the place value and the base-10 number system. Learners will find it easier to remember the abacus rules and understand the operations behind every movement on the abacus.
Our books use a great variety of visual stimuli to help young learners visualize numbers and play around with numbers. Additions and subtractions are not always presented in a straight-forward way in reality. When young learners are introduced to different ways of thinking numbers, they can build a solid foundation on their number sense which will greatly help their future learning in mathematics.
Our books include the training of addition and subtraction in a column format, as well as row format. Learners are trained with using the abacus to solve problems in the column format so that they can better understand the place value. On the other hand, the row format can alternatively train learners to solve problems mentally.
The book gradually increases the unit difficulty level to help your child build confidence. The alternated number– and bead– arithmetic calculation practices train your child to acquire simple addition and subtraction skills and build an abacus image in the mind.
Each unit contains both abacus training and mental training.
The books present a great variety of formats and different kinds of practice to help young learners play around with numbers. We want to make sure learners are exposed to different question styles so that they can tackle and solve problems in different thinking and different ways. Our learners will not get bored or robotized when working on our workbooks.
Advanced students will be trained with larger numbers and a long series of numbers in addition and subtraction. Moving the beads on the abacus will gradually become coded in the muscle memory. Learners do not need to think about how to operate on the abacus anymore. Instead, their fingers and their mind will operate automatically and consistently. Operations are presented in different formats so learners will not just always operate inside the box.
Tricks in addition and subtraction, multiplication and division are also introduced in the advanced levels of the workbooks. The goal of this section is to teach learners strategies to group numbers and simplify operations, as well as train their operational working memory. Increasing their speed in basic operations would save a bunch of time for some other challenging problems in a test. These strategies will be very useful for future Math Olympiad learning.
Students will improve their speed and accuracy on each test and unit review in the book.
If you think that Abacus training is just only about calculation, you're wrong.
It also trains students' concentration, eye-hand coordination, operational working memory, visual-spatial memory, and muscle memory.
Additional but essential practice --
Early Math is great for pre-schoolers and kindergarteners. Visual Math is great for kindergarteners and 1st graders.
A solid foundation for building number sense and visual-spatial skills. This series of workbook can help learners build a conceptual understanding of numbers and introduce them to different areas of mathematics.
Additional but essential practice -- Great for 1st graders to 3rd graders. A solid foundation for the four operations helps boost the speed and accuracy for problem solving. This series of workbook can help learners build a conceptual understanding of multiplication and division.
