수학연산연습(초등4학년1학기) - 이전 교육과정

Important Notice: This version of the app has been created based on the previous curriculum. Due to challenges in continuously updating resources while working in education, a new app based on the current curriculum has not yet been developed. However, I have made this available in the hope that it may assist some students. For those seeking an app aligned with the 2015 curriculum, it is advisable to explore alternative options.

Greetings, we are Park Kyung-jin from Seoul Semyung Elementary School and Lee Jae-wook from Seoul Gunam Elementary School.

In our experience teaching mathematics, we often encounter students who understand calculation methods but struggle with speed. To address this need, we developed this app.

Key Features of the App:

• The app includes gesture functionality, allowing users to perform calculations manually.
• Users can select the number of problems to practice from options of 5, 10, 15, 20, 25, or 30. (While it is possible to generate a vast number of problems, we limited the number to prevent overwhelming students.)
• The app facilitates step-by-step and comprehensive practice of multiplication, division, addition and subtraction of fractions for the first semester, and addition and subtraction of decimals for the second semester.
• Problems are generated randomly, ensuring that identical questions do not recur. (Each question is newly created rather than being selected from a pre-existing set.)
• Automatic grading occurs upon completion of all problems, with practice results reflected in statistical data.
• Considering the limited availability of tablets in schools, the app has been primarily designed for smartphone use.
• A statistics section allows students and teachers to review practice sessions and identify areas where students may require additional support. Clicking on specific entries reveals detailed results for individual problems. (While students may not appreciate this feature, they are unable to delete their recorded progress.)

We sincerely hope this resource can be of some assistance to teachers, students, and parents alike.

May God's love always be with you. "Believe in the Lord Jesus, and you will be saved—you and your household." (Acts 16:31)
