Maths Little Genius is a simple app that develops a user's confidence with topics commonly regarded as areas of weakness across an age range of 8-16+. Depending on ability and regularity of practice, Maths Little Genius can help students to cope with more complex Mathematics in the future by addressing what I consider to be the core skills now.

Although the device has been tested on both specific tablet and phone devices, your device may react differently. The only issue that has arisen for some devices is on the initial log in screen. You might be able to type your username in easily, but will then have trouble typing your password in. To get around this, please turn your device from portrait to landscape. This may help as the text box becomes larger. Once you have logged in, you can return to portrait again.


I have been teaching in the UK for over 6 years. In this time I have been an Acting Subject Leader of Mathematics and am now an Advanced Skills Teacher. I am currently working in a successful secondary school and thoroughly enjoy sharing my passion of Mathematics. Throughout my career my students have always done incredibly well. Part of their academic success is down to practicing the basic skills in Maths. By addressing issues of mental or written arithmetic earlier on, it opens doors to a wider range of topics to develop a broader understanding of the subject in the future. Little Genius is a simple app that I have designed in my spare time to help build self confidence and assessment with some of the basic skills in Maths.

I hope you enjoy it!!
