Although e-learning can be used independently by students, the existence of teachers is very meaningful as adults who function to support and assist students in the learning process. Therefore, a learning model that combines (blending) the face to face learning method with e-learning in an integrative and systematic manner will make the learning process more meaningful. The outbreak of the Corona virus in Indonesia has directed the learning situation to online learning. However, the fact is that the use of technology is still very minimal in schools. The same thing was found in the Mitra school. MA Cahaya Harapan is a partner school for this PKM workshop, where most teachers have not maximally utilized the use of ICT in the learning process in the classroom. The stages of this workshop include the stages of preparation, implementation, evaluation and mentoring. The purpose of this mentoring and training workshop is to improve the abilities of teachers in Moodle LMS-based blended learning in the post-Covid-19 era.

Mathematics is a human activity carried out in daily life both consciously and unconsciously such as measurement (geometry) or arithmetic calculations, but in its implementation there are still many who find it difficult to understand mathematics. The availability of instructional media is one of the factors that is less optimal in class learning. The activity of this community partnership program aims to introduce Information and Communication Technology(ICT) in learning and provide training to design teaching materials using ICT. The methods of implementing community partnership activities are training, the formation of a training team for trainers (TFT) and ICT-based teaching materials. The results of the implementation of these community partnership activities are the activities of the community partnership program by conducting training by transferring knowledge and technology to create learning designs for mathematical realistic worksheets based on ICT to get positive responses from SDIT teachers in one of West Bandung regencies. ICT training for mathematics teachers must be developed so that they are more skilled in using ICT in the learning of mathematics in class and are skilled at making ICT-based learning designs and to make use of them in the revolutionary 4.0 era.
