How to Use Number Ranges

  • To specify a range of consecutive numbers, enter the first and last number separated by a hyphen. For example, to specify all numbers between 5 and 10 inclusive, enter 5-10.
  • To specify several non-consecutive numbers, separate each one with a comma. For example, for the numbers 1, 5 and 9 only, enter: 1,5,9.
  • Ranges can include combinations of these two elements. For example, to specify the numbers 1, 3, and all the numbers between 10 and 15, enter: 1,3,10-15.
  • Negative numbers can also be entered. For example, to specify all numbers between -2 and 4, and all numbers between -10 and -5, enter: -2-4, -10--5. Don't worry if you end up with two hypens in a row - Worksheet Genius will figure it out.
  • Numbers do not need to be entered in ascending order. For example, 13,5:9,20,-5 is fine.
  • You can specify a step size between each number in a range - this can be used to generate multiples. To generate all the multiples of 5 between 5 and 100, enter 5-100(+5). To generate all the odd numbers between 1 and 20, enter 1-20(+2). To generate all the two digit numbers ending in 6 between 16 and 106, enter 16-106(+10).

For those of you that preferred our older method of using a colon to define a range (5:10, for example), you can still use that too if you want to.

What are Addition Pyramids?

Addition pyramids are a pyramid of numbers that can be used to help students visualize addition. The bottom row is filled with random numbers and next row up is the sum of the two numbers that are directly below it.

You can create number pyramid worksheets using this generator for simple 3 row pyramids, up to larger 9 row pyramids to challenge more advanced students.

Another option is to select the "Fill in random numbers" option, which will randomly choose numbers on different rows. With this, students will need to use addition, subtraction, and logical deduction as necessary to complete the addition pyramid by filling in the missing numbers:
