"Fast Clock and Time for Busy Elementary School Students"

We've collected all the clocks and time that elementary school students find difficult in one book!

■ Many children have difficulty with the concepts of time and vision.
“What is the difference between time and hour?”, “I’m confused about AM and PM.”, “It’s hard to change the time units.”, “How do I read a torn calendar?”

One of the areas that children struggle with in early elementary school math is the time domain.
The time zone, which is difficult for both children and mothers, is also called the swamp or hidden danger of elementary math among mothers.
In particular, the 'Vision and Time' unit, which is taught in the second grade, is difficult for children because they learn many concepts in a short period of time and the concepts are abstract.
So, if you skip over it without proper understanding and practice, you will have difficulties in the 3rd grade 'Calculating Time'.
Therefore, it is better to start from the first and second year and practice sufficiently.

■ Let's gather all the clocks and time learned in grades 1, 2, and 3 and practice them!
The time domain, which is most closely related to daily life, is learned in the subjects of 'Watching the Clock and Finding Rules' in the second semester of the first grade, 'Time and Time' in the second semester of the second grade, and 'Length and Time' in the first semester of the third grade.
This book covers everything from looking at the clock to time and time, and calculating time (calculating time without carrying over or carrying down).
We reduced the content that was too easy in the first grade and increased the content on visual and time aspects of the second grade that children often make mistakes on and have difficulty with, to provide more flexible problem arrangements.
Therefore, by studying with this book, you can gather all the scattered concepts of visual and time domains learned in lower grades and build a solid foundation at once.

■ Let's practice 'clocks and time' accurately step by step from the basics!
This book is organized by connecting the most basic learning, reading the clock, to reading the hour and 30 minutes (first grade, second semester course), reading in 5-minute and 1-minute units (second grade, second semester course), and reading in seconds (third grade, first semester course).
Sight reading is different from number reading.
We need to start by practicing reading and writing correctly, such as 'three-si' instead of 'set-si', and 'four-si' instead of 'four-si'.
Accurate sight reading also helps children excel at 'sight reading in multiple ways' and 'calculating time taken', which are common mistakes.
Please help me build a solid foundation from the ground up with this book.

■ Learn concepts easily with pictures and fill-in-the-blanks!
This book is structured so that you can first see the concepts in pictures and then fill in the blanks to understand them on your own.
And we help you understand through quizzes that confirm concepts and a corner that answers your questions.
When converting units of time, it is important to first show a clock and explain why there are 60 minutes in an hour rather than mechanically calculating how many hours to minutes.
Because you can understand ‘time and vision’ accurately only if you know the principles.

■ After solidifying the concept with training problems, we will challenge ourselves with everyday word problems!
Now that you understand the concept, you should practice with an appropriate amount of problems.
This book is structured so that you learn the concepts one by one, and then review them together.
And naturally, it leads to basic sentence structures and challenges sentence structures in daily life.
You can also summarize the concepts broken down by unit by solving fun final problems.

■ You can start studying in an interesting way by presenting the history of watches!
This book first introduces the history of watches before going into full-scale study.
From the sundials used by the ancient Mesopotamians to the Egyptian obelisks, huge, pointed stone pillars, sundials and water clocks, to the digital and analog clocks we use today, the history is introduced through interesting pictures and text.
Children can develop an interest in clocks and begin to study them.

■ This book's progress chart! Have fun achieving your learning goals with "Padok in Wonderland"!
The beginning pages of each yard in this book are designed to help you escape the 'Wonderful Clock World' with Padok while coloring the steps you studied today.
After you finish this book, which consists of three chapters, you can enjoy dinner with your friend, Ppuniy.
Children will be able to let their imagination run wild as if they were Alice in Wonderland, and feel a greater sense of accomplishment when they finish a book.

? Wow~ This is the workbook I was looking for.
I needed a workbook that focused on the parts of the clock that I was lacking, rather than covering the entire curriculum! - ppuppu5
I often find myself stuck in a black hole of clocks and time, so I'm glad this book came out! -Doksun-gwiyomi-ne
