"Buss Mental Arithmetic" supports pupils from the first practice to the perfection of mental arithmetic and is therefore suitable for pupils from the first to the fifth grade.
The acquired skills form the basis for fast and reliable written addition, subtraction, multiplication and division.
Via the "Basics" button (button with ring and "B") on the start page, you reach the area that is used for the first practice and memorization of the basic arithmetic operations.
The other buttons of the start page, marked with the symbols of the basic arithmetic operations, lead to the area for advanced users, in which the emphasis is on a significant increase of the calculation speed as well as a strengthening of the ability to concentrate.
With regard to addition and subtraction, the area for advanced users is suitable for pupils as soon as they calculate over the tens (e.g. 8 + 5 = 13, 17 - 9 = 8).
With regard to multiplication and division, the area for advanced users is suitable for pupils as soon as they calculate with all multipliers from 0 to 9 and all divisors from 1 to 9 respectively.
In the app "Buss Mental Arithmetic" only addition is freely available in the advanced area. In the basics area addition, subtraction, „2-times table" to „4-times table" (multiplication), "Divided by 2" to "Divided by 4“ (division) are freely available. All other functions are locked and can be unlocked by a one-time In-App purchase.
A. Basics Area
In the basics area you can choose between addition, subtraction, multiplication and division. Depending on the selected basic arithmetic operation, different task types can be selected. In the case of multiplication, for example, the pupil can select the 3-times table. If the pupil then chooses the "Practice" button, he will be presented with tasks from the 3-times table that he has to solve.
In the case of multiplication and division there is a "View" button next to the "Practice" button. If this button is selected, for example in the case of the 3-times table, an overview with all tasks of the 3-times table including the solutions is presented.
B. Advanced Area
For each of the 4 basic arithmetic operations as well as for "Mixed" (button with all four arithmetic symbols) the app offers the functions "Practice", "Test" and "Test Results".
Within the "Practice" function, the child receives feedback directly after each task. This function serves as preparation for the "Test" function.
If the "Test" function is chosen, he or she receives 100 different tasks one after the other (90 for division), whereby the feedback only occurs after all tasks have been completed. This powers the ability to concentrate and leads after some tests to a significant increase of the calculation speed. The test result then contains a list of errors (if there are any) as well as the time required for calculating.
The "Test Results" function allows him/her to view the development in terms of the number of errors and the time required. In addition, the errors per test can be listed in a detailed view.
The test results can also be saved without entering a user name. If you want to enter one or more usernames, you don't have to enter your real name and/or first name.
Both test results and individual users can be deleted at any time. If a user is deleted, the test results generated by him are also deleted at the same time. It is also possible to delete all users at once, including their test results.
All data entered and generated during the use of this app is only stored locally on the respective device. The app does not send any entered information to my company or to third parties.
Internet access is required for the in-app purchase as well as for the case of an unsuccessful receipt evaluation (receipt for the optional in-app purchase). Otherwise, this app does not have Internet functionality.
Have fun practicing.
What's new in v2.0
The graphic elements (buttons, text, etc.) are displayed larger on iPads with a screen diagonal of 10.5 inches or larger.
In addition to the previous functions, practices and tests with randomly mixed basic arithmetic operations (Plus, Minus, Paint and Split) can now also be done. The "Mixed" area can be reached via the button with all four arithmetic symbols on the start page.
An additional extension is the basics area, which is used for the first practice and memorization of the basic arithmetic operations. This can be reached by pressing the button on the start page with the ring and the letter "B". In the case of multiplication, for example, the pupil can select the three times table. If the pupil then chooses the "Practice" button, tasks from the three times table that he or she has to solve will be presented.
In-App purchase: In this app version only the basics and advanced areas for addition are freely available. All other functions are locked and can be unlocked by a one-time In-App purchase. When upgrading from version 1.0 to this version, all functions are freely available even without In-App purchase.
