The paper has discussed on the development of prototype of a
mobile application, MathDS for Down syndrome children.
This development is based on behavioural, cognitive and
constructive learning theories and ‘TouchPoint” concept. The
app is an early study on the development of a learning tool for
DS children which focused on numeracy skills. It is proven
based on the research conducted on literature review of their
learning theories and user acceptance result conducted to
several types of respondents. Besides that, as a personalized
system, this mobile application on numerical skills has been
developed which is a new way to assist them in knowing and
learning basic numbers. Hopefully, this mobile application
with the suitable learning concept will be beneficial and can
help as well as support Down syndrome children in learning
mathematics.
