What is the Exercise Generator?
The addition and subtraction exercise generator creates simple exercises for first-grade students or preschoolers.
Usage
To create a new exercise, simply select whether you want addition or subtraction by choosing "Plus" or "Minus" in the "Select operation" section. Then press the "NEW EXERCISE" button and you will see numbers in the fields below that form the exercise. Enter your answer in the third field and verify it with the "CHECK" button. (Don't be startled by the sound ;-)
Creating exercises manually
You can also create exercises yourself. Enter digits in the first two empty fields and the result in the third. Be careful when changing the operation sign. The currently displayed sign applies for checking the exercise. To change the sign, select the desired operation and press the "NEW EXERCISE" button. This will generate a new exercise and change the sign. Then you can write your own exercise.
Difficulty levels
The exercises have five difficulty levels:
- Up to 10: The sum of two numbers is always at most ten. For subtraction, the first number (minuend) is at most 10 and the second (subtrahend) is always less than the minuend.
- Up to 20 without crossing 10: For addition, the sum is max. 20. The first number is between 10 and 20, the second is max. 10. For subtraction, the minuend is max. 20 and the subtrahend is set so that the result is not less than 10.
- Up to 20: Addition - The sum is at most 20, one number is always up to 10.
- Up to 100 without crossing tens: One number is always at most ten, the other is set so that the sum of the two numbers does not cross a multiple of ten.
