PKM activities are divided into two activities, namely educational seminars and teaching aid exhibitions. Educational seminar presented by Dr. Nilamsari Kusumastuti. He introduced the fun of learning mathematics without having to think or calculate specifically. In the presentation of the material, several games are also introduced that are connected to the concepts of arithmetic, algebra, geometry and statistics.

Nadila Nur Aulia, one of the participants from class XI Science 1 was very enthusiastic about taking part in the activity. “I liked the way the speaker explained mathematics in the form of games that we face in everyday life. "Hopefully what happened today can be useful in the future," he said.

In the second activity, there was an exhibition of mathematics teaching aids. Guided by the PKM PS Mathematics TEAM, the teaching aids provided can be tried directly by participants to help solve mathematical problems. All of these educational games were participated in very enthusiastically by the participants. Apart from that, participants can also take photos together at the PS Mathematics photobooth which has been provided at the location.
