Some of the most popularly used types of multiplication table worksheets are for the numbers 1 through 10 and 1 through 12. Negative number times table sheets are also used in schools across the United States. Problems are usually placed in grid patterns but can occasionally be arranged in circles.
On typical times table worksheets, problems are arranged into horizontal and vertical lines, increasing down and to the right by numerical value. Many different types of problems can fit into this configuration, such as tables of consecutive numbers 1 through 12 or tables of single digits multiplied by 10. Sometimes, problems on multiplication worksheets are arranged into concentric circles.
