6 pages per day, 20 days of study
Improve learning immersion with six pages of daily calculation intensive study.

Complete your calculation concepts with easy-to-understand core concepts.
Organizes core computational concepts essential for secondary mathematics into an easy-to-understand format for students.

A textbook that bridges elementary and middle school mathematics
Learn how what you learned in elementary school is connected to the secondary curriculum and how the same concept is expressed differently in elementary and secondary school.

Completing calculation skills through achievement assessment
After completing 20 days of study, you will be assessed twice to check your calculation skills for all units.

1.
A textbook that teaches the basics of middle school mathematics before entering middle school.
Learn numbers, operations, letters, and formulas, which are the foundation of middle school mathematics.
In 7A Numbers and Operations, you will learn how to factorize numbers and about integers and rational numbers.
In 7B Letters and Expressions, you will learn how to use letters to calculate expressions and about linear equations.

2.
A textbook for prospective middle school students who find the secondary mathematics concept book difficult.
This textbook is for students who want to advance in middle school mathematics but find middle school concept and calculation books difficult.
It covers middle school math content, but is designed to be as easy to learn as possible for elementary school students.

3.
A textbook that bridges the gap between elementary and middle school mathematics by highlighting content related to the elementary curriculum.
This textbook covers middle school math content, but also links it to content learned in elementary school, lowering the barrier to middle school math.
