Are you looking for a way to provide your child or students with additional practice working math problems? Do they grow tired of worksheets? If so, then our new Interactive Math Machine may be just what you need. There are over forty types of math problems to choose from. Currently we have whole number practice available for addition, subtraction, multiplication, and division. Click here to see a list.

Each time Math Machine starts, it generates a new, random set of math problems. The problems are presented to the student in a format which simulates a paper worksheet, only better. Instead of a blank sheet of paper, Math Machine guides the student from one step to the next. If the student is unsure how to work a problem, the help button is always available to provide the correct method for working that type of problem.

Upon completing work on a problem, the student must click the "Check" button, which marks up their work to show any errors. This immediate feedback keeps students from continuing to practice incorrectly.

At the end of the set of problems, Math Machine presents a score to the student based on the correctness of his or her work and the speed in which the problems were completed. This feature allows your student to compete against his or her best score, encouraging additional practice.
