Textbook guide providing detailed explanations of problem-solving methods in arithmetic. - Title: Elementary School Arithmetic 5th Grade Textbook Guide - Series: Textbook-Based Edition - Usage: Explains problem-solving methods - Publisher: Bunri 2860 yen I used to teach my child myself, but from 5th grade, we started using a cram school, so this book is unused. When my child suddenly asks a question, I sometimes can't explain it right away, but this book is helpful in those situations, so I recommend it. It includes all the problems from the textbook, so it's also useful when your child forgets to bring their textbook home for homework, haha. For advanced learning in 4th grade.
