Table of Contents Problem Type There are 12 problem types: Add, Subtract, Multiply, Divide, Add / Subtract, Multiply / Divide, Mixed, Add (Missing Number), Subtract (Missing Number), Multiply (Missing Number), Divide (Missing Number), Greater / Less Than.

The first six types are self-explanatory. The fifth type, Mixed, allows a fact sheet to be created which contains a mixture of types 1-4 and 12. The Missing Number types include either a missing numerator or denominator as part of the problem. Finally, a Greater / Less Than problem allows a student to determine the greater/less than relationship between two numbers. [top] Description When creating and printing fact or answer sheets, you may wish to provide a description of the type of problem set. A description that is entered will automatically appear at the top of the fact or answer sheet. [top] Font Size The font size that is used to create a fact sheet can be changed to allow more or less problems per page. By selecting a smaller size, more problems can normally be presented horizontally as well as vertically. [top] Division Answers When selecting the problem type Division, you may select how to present the answers when creating an answer sheet. Selecting "Normal" will automatically show each answer up to five decimal places. Selecting "Whole" guarantees that each division problem will result in a whole number. The third choice, "Two-decimal rounding" will generate all answers with a rounded two-decimal answer. This option is only active when generating a Division (and Missing Number) or Mixed problem type. [top] Options
  • Include Name/Date/Score fields - By enabling this option, each fact sheet will automatically have a page header which will include a space for name, date, and score. The header is not included on answer sheets.
  • Don't allow answers of -1, 0, or 1 - If you would like to guarantee that no answer has a value of minus one, zero, or one, enable this option.
  • Generate numbers with two decimals - Although not frequently used, if you would like your problem facts to have up to two decimal places, enable this option.
  • Jumbo space for working solution - By enabling this option, extra space will be included between each row for solving problems. The extra space is not included on answer sheets.
  • No negative results for subtraction - By enabling this option, you are guaranteed that no subtraction problem will result in a negative answer (helpful for children who have not learned negative numbers yet). This option is only active when generating a Subtraction (and Missing Number) or Mixed problem type.
  • Number problems from 1 to ... - By selecting this option, all fact sheet problems will be numbered from 1 to the highest number.
  • Display problems horizontally - This option controls how the addition, subtraction, multiplication, and division problems are displayed. By selecting this option, problems will be presented horizontally (e.g. 3+5=8) rather than the default vertical layout where one number is beneath the other.
[top] Row Layout The row layout allows you to specify how many rows and how many problems per row to create when generating a fact sheet. Both the row count and the problems per row values must be in the range 1-25. Depending on the font size selected, a standard 8x11 sheet of paper contains 6 rows of 5 problems each. [top] Range for Problems Creating a fact sheet problem requires the generation of a random numerator and a random denominator. In order to do this, a numeric "range" must be specified so that a number can be randomly selected from within that range.
There are three diffent ways to specify a range.
  • Single Range - Being the easiest to use to generate fact sheet problems, this method uses a single numeric range to select both the numerator and denominator. The low and high end of the range is entered as the "minimum" and "maximum" values. For example, if fact sheet problems are to have numerators and denominators which are single-digits, the minimum and maximum values entered would be "0" and "9". Example:

    Single Range

  • Dual Range - The dual range method allows a different range to be specified for each the numerator and denominator. For example, if you would like fact sheet problems that always include a 7 as one number and a single-digit number as the other number, the ranges would be "7 to 7" and "0 to 9" respectfully. This method allows the most flexibility in the generation of both the numerator and denominator. Example:

    Dual Range

  • Mixed Range - This method allows a mixed specification of both the single range and the dual range. More difficult to use (and not as popular), the mixed range method allows fact sheet problems to have either the minimum or maximum number entered as a range (i.e. "1 to 10"), while the other number is entered as a single value (i.e. "5"). When a mixed range is entered, the single value will be converted to a range using either the low or high value of the other range. For example, if you specify a range of "0 to 9" for the first number and "3" for the second number, the resulting ranges will be "0 to 9" and "0 to 3". For another example, if the first number is entered as "5" and the second number is a range entered as "1 to 10", the resulting ranges will be "5 to 10" and "1 to 10". Example:

    Mixed Range

    Numbers that are entered as a minimum, maximum, or a range value, must be in the range -9999 to 9999.

[top] Answer Range This optional input field allows you to limit the range of your answers. If entered, you must specify your range in the "low to high" format. To limit your answers to a number from 1 to 10, enter "1 to 10". Although easy for students to determine answers, your answer range can also specify a single result as in "9 to 9". Be careful to use answer ranges that make sense for your problem ranges. For example, don't create postive addition facts and then input a negative answer range. Failure to input valid answer ranges will result in an error page. [top] Lock Minimum/Maximum Ranges If you input ranges as the minimum and maximum values, this option controls whether those ranges will be used to select either a numerator or denominator.

If this option is not selected (the default), the numerator for a fact problem may be the result of either input range; the denominator will be selected from the opposite range.

If this option is selected, the numerator will be selected from the "Minimum or range" input value; the denominator will be selected from the "Maximum or range" input value.

Be aware that selecting this option can sometimes result in scenarios that cannot be resolved. For example, if you enable this option and select "No negative results for subtraction", a "Minimum or range" input value of 1 to 1, a "Maximum or range" input value of 5 to 10, you will receive an error (you cannot subtract a value 5-10 from 1 and get a positive result).

Generate! The Generate! button allows you to build your fact sheet. Once you have entered the required fields and selected any options, you may select one of three different Generate! choices (listed below). After selecting your choice, click the Generate! button to process your request.
  • Generate fact sheet - This choice will create and display your fact sheet (without answers). Each sheet will be displayed in a new browser window. Once displayed, you can review and/or print your fact sheet. On many browsers, you can move your mouse over each individual problem to view the answer.
  • Generate answer sheet - This choice will display your fact sheet (with answers). Each sheet will be displayed in a new browser window. Once displayed, you can review and/or print your answer sheet.
  • Automatically email me daily - This choice will provide you the opportunity to automatically receive a "re-shuffled" set of problems for your fact sheet on a daily basis. Once you click the Generate! button, you are allowed to enter your email address and select which weekdays you would like to receive email. Each email received will contain an Internet link to generate a different set of problems, specific for that day. All fact sheet problems are based on the settings you entered for your fact sheet.
[top] Re-Shuffle For each set of options you select on the build page, you will get the same problems each time you click the Generate! button. If you are not satisfied with the problems generated for you, then you can click the Re-Shuffle button. Once you click Re-Shuffle, you can re-click the Generate! button to generate a new set of problems. There is no limit to the number of times you can re-shuffle your problems. [top]
