Free Number Sense Worksheets
All number sense worksheets available on this page are free. The number sense worksheets contained on this page can be used as assessment tools, extra practice for students learning their basic number facts, and any other purpose that you see fit. Each worksheet comes complete with an answer key which can be used for self-correcting or marking. The "+-" value in brackets refers to how close the sets of two numbers are together. For instance, +-9 means that the first number is up to 9 larger or 9 smaller than the second number. The regular comparing worksheets contain randomly-generated pairs of numbers. I included commas to separate the periods (groups of three) in large numbers. If anyone would like periods separated by spaces (as is used in SI notation), please let me know.
