On the left-hand side of the home page, you will find a list of worksheets organized by topic. If you select multiplication, for example, you’ll then be presented with a list of multiplication worksheets you can choose from. Once you’ve selected one, you can then set the exact parameters you wish to address in the worksheet, including the number of digits involved, the number of problems on each worksheet, and even the language you are being tested in. This allows you to really customize your experience to be as relevant as possible. Once you’re satisfied with the parameters you’ve chosen, all you need to do is click the “Create It” button. One of the best parts about Mathaids is that it generates a brand new, dynamically produced worksheet each time you click that button on. In other words, users benefit from practically infinite variations of the question types they need to practice. In addition to the menu on the left side of the home page, you can also utilize the search box on the right-hand side to target your areas of interest with ease.
