About these worksheets
Number work rewards repetition with different numbers rather than the same sheet twice. Every sheet is generated fresh, so you can print a new one on the same skill as often as you need — different numbers, same difficulty.
Pick how many problems you want and whether they should be easy, medium or hard, then download a PDF with a matching answer key. The key can show the worked steps for every problem, which is what a parent needs to see where a wrong answer went wrong.
