BTA2023 AWARD-WINNING PRODUCTS ANNOUNCED!

How to teach? Gakken Plus has developed a complete application of clock work for young children. The "GURU-GURU-TOKEI" function, which gives children a thrilling feeling, deepens their understanding of the subject.

From the Editor

Gakken's toddler work "Toukei", which is sold at bookstores, etc., has been made into a complete app, available on Google Play, AppStore, and the Amazon app store.

Some of the content is digitized with the goodness of paper work, while the app's own "Gururutokei" allows the user to move the clock around as much as they like, and the hands can be moved with the fingers to deepen the study of the clock.

Let's take a look at the details from the press release.

- Below is the content from the press release--

The app's unique "evolution" includes the ability to answer the time by turning the hands by yourself! With question narration and a timer to prevent overdoing it, you can easily learn by yourself!

(Tokyo, Japan / President and COO: Tatsuya Nanjo), a group company of Gakken Holdings, Inc. (Tokyo, Japan / President and COO: Tatsuya Nanjo) released "Gakken's Preschool Work-Tokei: Analog Clock Keiko" on the Amazon App Store on Tuesday, August 23, 2022.

My son can read a digital clock, but he has a hard time with analog clocks... "Why does it say '5 minutes' when it says '1'? I tried my best to explain it to him, but he still couldn't understand.
How can I teach them how to read an analog clock? We have developed an application that we recommend to families who are struggling with this question.

Gakken's popular "5-6 year olds' tokei" toddler work is now available as a complete application.

Gakken's Toddler Work," which is sold in the infant drill section of bookstores nationwide, is a very popular workbook that has been published for 40 years and has sold a total of 50 million copies.
Among them, "5-6 Year Olds' Tokai" has been very popular as a book that helps children understand everything from how a clock face works to how to read the hours and minutes, with cute illustrations that suit children's daily lives. This book is now available as a complete application.

■I'm enjoying the movement that only an app can provide!

While writing on paper with crayons and pencils is essential for the development of young children, the movements and sounds unique to apps also provide a good stimulus for children.

The problem of putting a sticker on the dial (left) and the problem of maze. Selecting the answer at the fork in the road (middle and right).

When you have finished answering the questions, click the "Done" button. If all the questions are answered correctly, a big round circle will be displayed on the screen, which will make your child smile and say, "I did it! and smile.
If they get a question wrong, they can go back and redo it and keep trying until they get a big round circle.

Stickers for your efforts

After Hanamaru, you will also get "Ganbari stickers", which you can check in your Okeiko list.
If you collect all 70 Ganbari stickers, you will get a special certificate screen.

■ぐーるぐるぐる…ついつい回したくなる「ぐるぐるとけい」

The book also includes a clock that can be operated by yourself (Gurugurutokei), which could not be realized in the paper book, for a deeper understanding. When you turn the clock, you can enjoy the sound of the clock, which is just like playing with a math set clock. You can enjoy the sound of the clock as it goes round and round.

▲I can touch the long hand and spin it round and round ...... and find myself spinning it all the time.

A digital display in the lower right corner allows you to quickly check the time you have set.
There is also a problem in the "Keiko" game where you have to "set the time and answer by yourself" using the GURU-GURU-TOKEI mechanism. Because you set the time by yourself, you will understand more deeply.

When answering, the screen is magnified, so it can be operated even on the small screen of a smartphone.

■All questions are narrated

You can check how to do the problems by clicking on the "How to do" button and the problem text by clicking on the "Listen" button at any time during the lesson, so you don't have to be with your child all the time. This means that your child can easily progress without you having to be there all the time.
A timer function is also included to prevent overdoing the work. The time can be set from the gear mark in the "For Family" section. When the set time comes, the message "Rest your eyes.
This function can be used as a timing for making a promise to your child, such as, "You have ● minutes to play with the application.
