By PUTUNG – We are KKN participants from Petung Posko Village 2 teaches students to be precise in class IV of SDN 3 Instructions for calculating using Jarimatika. Jarimatika is an abbreviation of Jari and Mathematics. Jarimatika is a way of calculating mathematics for students using their fingers.
Its application is shown to be a student's first bridge into the world of mathematics which is considered difficult. We teach Jarimatika to fourth grade elementary school students 3 Petung because they still find it difficult to calculate mathematics, especially mathematical multiplication. To make learning mathematics more interesting, We collaborate with educational games using Snakes and Ladders media.
Snake and ladder media is made from cardboard that is numbered 1 until 50 Don't forget the picture of snakes and ladders, and some numbers are marked with a stamp. Besides that, We make cube nets in such a way that they are shaped like dice in the snakes and ladders game but with a larger size.
Before the educational game begins, we teach the theory of mathematical multiplication, After they understand enough about the theory and application of mathematics, we divide class IV students into 6 group. Don't forget to convey several rules for implementing it. One of them is that when a group stops on a number with a stamp, that group will get a Jarimatika quiz.
The educational game lasts approx 2 jam. The students were very enthusiastic in the game. Apart from practicing mathematical skills, this game also teaches students the importance of teamwork.
In the educational game snakes and ladders, 3 the group that reaches first finish will be the winner and get reward that we have prepared. We feel very proud when we see them sharing gifts with friends who are not so lucky. Hopefully this educational game can improve students' abilities in multiplication and solidarity.
