Basic Fact Help
Table of Contents
There are 13 problem types:
- Add / Subtract
- Multiply / Divide
- Add / Subtract / Multiply / Divide
- Add (Missing Number)
- Subtract (Missing Number)
- Multiply (Missing Number)
- Divide (Missing Number)
- Greater / Less Than
The first seven types are self-explanatory. The Mixed type allows a fact sheet
to be created which contains a mixture of the basic arithmetic types. The Missing Number types
will result in one of the problem numbers missing, but with the answer included. Lastly, a
Greater / Less Than problem allows a student to determine the greater/less than
relationship between two numbers.
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.
The text 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.
The following are options for generating worksheets.
Name/date/score - By enabling this option, each fact sheet will automatically have a page header
which will include a space for name, date, and score. This header is not included on answer sheets.
Number problems 1... - By selecting this option, all conversion problems will be numbered from
1 to the highest number.
yada yada yada
yada yada yada
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.
Create 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.
Extra solution space - 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.
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
Lock min/max positions - If you specify your minimum and maximum values as a range, this option controls whether
those values remain locked as either the top or bottom (left or right) positions. If not, then the generator will
randomly decide which position the numbers will appear in.
Note: 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).
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.
Creating a fact sheet problem requires the generation of random values (number1, number2).
In order to do this, a numeric "range" is specified so that individual number values will be
generated for each problem. There are three diffent ways to specify a range:
Simple Range - Being the easiest
to use to generate fact sheet problems, this method uses a single number range
to select both number1 and number2. The low and high end of the range
is entered as the "Minimum" and "Maximum" values. For example, if fact sheet problems
should have number1 and number2 which are single-digits, the minimum and
maximum values entered would be "0" and "9". Example:
Number Range - The number range method
allows you to specify a sequential number range to be specified for number1 and/or number2.
For example, if you would like fact sheet problems that always include a number from 2 to 5 as one
number, and a single-digit number as the other number, the ranges would be "2 to
5" and "0 to 9" respectfully. Example:
List Range - This method allows you a largest amount of flexibility to tailor your fact sheet problems.
For your input, specify a list of numbers to use in for
number1 and/or number2; separate your list of numbers with commas.
The generator will randomly select one of your list numbers. Example to practice a single digit number
by single digit odd numbers:
Another great example of using the List Range is to practice a specific fact family. To accomplish this, enter a
Number Range along with your List Range (only include a singe number in your list...the fact to practice).
Example to practice the 3 fact family:
This optional input field allows you to limit the range of your answers.
You can only use the Number Range or List Range range formats as described in
the Number Ranges section.
Be careful to only use answer ranges that make
sense for your problem ranges. For example, don't create positive addition facts
and then input a negative answer range. Failure to input valid answer ranges will
result in an error message.
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
Once you have entered the worksheet creation data, and selected any options, you may choose to generate either the worksheet problems
or answers, or bookmark a link for daily use.
Problems - This choice will
generate and display your worksheet (without answers). Each worksheet will
be displayed in a new browser window. Once displayed, you can review and/or print
Answers - This choice will
display your worksheet (with answers). Each worksheet will be displayed in
a new browser window. Once displayed, you can review and/or print your answer worksheet.
Daily link - This choice will display a Internet browser link, preserving your custom worksheet settings.
You can bookmark (i.e. save) this link for later use.
Visiting this link will display your custom settings for generating your worksheet.
The generated worksheet will contain a unique set of problems, specific for that day.
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.
