Answer and solution

Quick Mixed Fractions and Decimals for Busy Elementary Students

Things you must have before entering middle school
Solidify your knowledge of 'mixed fractions and decimals'!
The secret of a math academy famous for teaching well: intensive training focused on mixed calculations!

■ Why do we need to focus on mixed calculations separately? ‘Mixed calculations’ require focused practice, just like ‘multiplication tables’.
For friends who are accustomed to calculating from the front, 'mixed calculations with various operation symbols' require a process of memorizing the calculation order and becoming proficient through sufficient practice.
So, math academies in Daechi-dong say that they create a separate workbook containing only mixed calculation problems during vacation and provide intensive training.
This book focuses on 'mixed calculations with fractions and decimals'.
The revised curriculum focuses on reducing the scope of study, and 'mixed calculations with fractions and decimals' have been removed from elementary mathematics.
However, since mixed calculations with fractions and decimals are essential when solving application and utilization problems in elementary mathematics, it is something that must be trained if you dream of being at the top of the mathematics rankings.
Finish up fractions and decimals, a core part of upper-grade math, with 'Quick Fraction and Decimal Mixing for Busy Elementary Students'!

■ The 'lump calculation method' of the 'busy calculation method' that catches mixed calculation mistakes Even if you know the calculation order, if you only think about it in your head, it is easy to make the mistake of calculating the part that is easy to calculate mentally first when solving a problem.

This book presents and focuses on the secret to catching mistakes in mixed calculations by first grouping the parts to be solved into chunks.
For example, in an expression where addition and subtraction are mixed with multiplication, the multiplication part is grouped together and then calculated.
This secret is a teaching tip from Dr. Hosara, who has been teaching gifted children at the Bundang Gifted Love Education Research Institute for 17 years.
By grouping them into chunks, long equations are simply transformed into equations that mix additions and subtractions, so long equations become less intimidating and you can catch mistakes in the order of calculations!

■ If you want to do well in middle school math, it's not an option, it's a must! 'Mixed Calculations with Fractions and Decimals' The 'Integers and Rational Numbers' unit, which is studied in middle school, covers mixed calculations with a wider range of numbers than the 'Mixed Calculations with Natural Numbers' content of elementary school math.
Due to the nature of mathematics as a subject with a strong systematic structure, in order to maintain a good flow of mathematics, you must be able to do 'mixed calculations with fractions and decimals' well, and then you can intuitively and easily solve 'mixed calculations with integers and rational numbers'.
Therefore, I recommend that you thoroughly understand this part before entering middle school.
If you build a solid foundation in 'mixed calculations with fractions and decimals', you'll be good at middle school math too!

■ An efficient learning method that builds real skills through flexible training! 'Fast Fraction and Decimal Mixed Calculations for Busy Elementary School Students' challenges problems that gradually become more difficult through sufficient arithmetic training.
Additionally, we present a learning method that builds real skills more efficiently in the same amount of time by structuring it so that you can become proficient in 'mixed calculations of fractions and decimals' rather than just being able to solve them through short-term, flexible training.
Steps that require simple practice can be quickly checked and passed over, and steps that require more learning are expanded and structured to allow for sufficient training.

Additionally, it is structured so that you can study intensively in a short period of time by solving 2-3 levels per day within 10-20 days.
If you study intensively, you can easily understand the overall context, which reduces the time it takes to complete a book, and like snow that piles up when you pour it down, your skills will gradually build up.
If you focus on practicing 'mixed calculations with fractions and decimals' with this book, you will be able to finish elementary school math wisely and become good at middle school math.

■ Features of this book

1) Just 10 days to shape your math life! Customized learning is available at home after a diagnostic assessment!
We applied the actual diagnostic assessment methods of math academy directors to accurately diagnose your child's current learning status and create a customized learning plan even at home.
You can choose to study using either the 10-day progress chart or the 20-day progress chart based on the results of the '10-minute diagnostic assessment' included in this book.
If you want a quicker diagnosis, you can also check the progress chart that is right for you with the '5-minute diagnostic assessment'.

If you are a 6th grader, even if a 20-day progress chart is provided, we recommend that you focus on completing the calculations by challenging yourself with a 10-day progress chart.
Just 10 days to address your learning deficits will be a crucial turning point that will determine your future math career.


2) Don't solve it unconditionally! Look at the concept and 'get the feeling~'
If you solve problems without properly understanding the concepts, you may hit a wall at some point.
Just as you need to consume a balanced diet to build basic physical strength, you need to learn concepts and principles during the training process to build a healthy foundation.

Unlike training books that only contain calculations, Busy Operation Method includes 'concepts at a glance' for each lesson.
It is helpful for friends who are learning on their own, as it allows them to understand the principles and practice calculations through friendly concept explanations that can be understood just by looking at the title.

3) The teacher in the book! Solve the puzzle with the teacher using Padok's 'Honey Tips' and 'Wait! Quiz'!
No more mechanical, uninspired problem-solving! From useful tips to error-reducing tricks, this book offers easy-to-understand and easy-to-follow instructions.
After learning a concept, you can review it again with a "Quiz" so you can enjoy the benefits of studying with a friendly teacher even if you solve it on your own.

4) Scientific learning design! Baboo's "small steps" method builds skills!
No more mechanical, repetitive calculations! We've structured it so you can quickly learn the easy parts and practice more on the more challenging ones.
The more flexible structure allows you to learn more efficiently with the same investment of time, with stages that require simple practice expanded to 3 pages and stages that require more practice expanded to 4 or 5 pages.
Additionally, the level of immersion has been further increased by designing the stages meticulously and scientifically using the 'small step' method of Busy, which gradually increases the level and challenges.
It doesn't suddenly become difficult, so anyone can immerse themselves in it until the end and build their skills.

5) Understand the language of daily life and make it your own, and you will gain confidence naturally!
It doesn't end with just practicing simple calculation problems.
You can prepare for descriptive problems that you will definitely encounter in school, and also develop your thinking skills with fun arithmetic playground problems that are like games.
This book is not just about calculations, but it is more than just a book about calculations, and it helps you develop the problem-solving and creative convergence skills required by the current curriculum!
