Work Sheet (LKS) is one of the tools of mathematics learning is quite important and is expected to help learners found a massive and develop mathematical concepts. Technological development is so fast especially computers and the Internet. In the global era of the Internet as an alternative learning regardless of the time and place.
Providing knowledge, attitudes and skills that need to be owned by students is one of the intended use of the worksheets in the learning process. LKS model structure capable of delivering learners achieve the learning objectives with or without the help of mentors, but that does not mean the teacher is replaced but the teacher as a supervisor and a motivator. Internet is becoming an alternative learning model that is being developed. Pembelajran via the Internet without knowing the time and place will expedite and streamline the transfer of knowledge.
Model LKS web-based interactive mathematics, the contents of teaching materials developed in the form of questions used to direct learners to be able to find a concept or formula with previous knowledge. This is very different from a conventional worksheet that circulated in schools, LKS is more emphasis on practice problems.
