For example, the Illuminations website by the National Council of Teachers of Mathematics (NCTM) provides a great number of tried and proven lesson plans and online activities. For several of the activities you will also find a link to the activity on iPad. You can search on level and type of activity. An invaluable resource for each math teacher and tutor!
Have a look at the SHODOR.org website, a National Resource for Computational Science Education. They maintain a great website, under Activities and Lessons you will find ‘Interactivate’, showing students over 100 math concepts in a novel interactive way.
The additional advantage of websites for individual use is differentiation. Many programs just provide drills for arithmetic. We are now aware that speed drills for math facts can cause math anxiety. Luckily there is a growing number of websites that presents concepts in a novel and interactive way that is hard to do with text books alone.

The Number Race was developed for ages 4 – 8 developed by Dr. A.J. Wilson in collaboration with Dr. S. Dehaene from the Unicog Institute (INSERM) in Paris and is available for free from SourceForge in several languages. It uses recent research in neuroscience to specifically target youngsters with dyscalculia.
The London Knowledge Lab developed the Number-Sense website, with five highly acclaimed activities for students with dyscalculia: Learn Time, Number-bonds, Dots2Track, Number-line, and Chicks Test. (This website uses Flash, so not suitable for Apple Pc’s). The Number-bonds is a tetris like game where you combine the well known Cuisenaire rods to make ten. Different levels ultimately leading to the abstract notation. You will also find the contact to the Low Numeracy Network and can sign up for regular updates and new information on the topic.
The Khan Academy has super clear lessons presented on a ‘blackboard’ with oral explanations in all levels, from simple addition to multivariate calculus. There is a built-in progression, that takes students on a journey through the areas of Math and a progress monitoring system. Teachers can connect with their students using the Coach function. Unlike many educational computer programs that span only elementary, middle school or high school level, this one spans many levels, so the student on the verge of one of these school borders does not need to wait till graduation day…
Word problems area a huge stumble block for many students with dyscalculia, in particular those who also have dyslexia. Thinking Blocks, by Math Playground, is based on the Singapore way of using strips to represent numbers. Students are guided step by step through the process of problem solving. You can choose from word problems focusing on Addition-Subtraction, Multiplication-Division, Fractions, and Ratio-Proportion. It is available as PC game and on iPad.
The Connected Mathematics Project for Middle School at the University of Michigan offers a lot of information, not only math content for students, but also a section with in depth explanations for parents, who like to help their teenagers and interactive resources, including online math games using Java: Connected Math
A newer website for Middle and High School is SchoolYourself.org It offers great oral explanations and clear visuals. Students are asked to participate in various points during the explanations and hints are provided to go to videos where you can brush up the required basic knowledge.
