Realistic Mathematics in Snake and Stair Game

Addition and subtraction number concept is introduced to students since they are in grade 1 in elementary school. They study addition and subtraction for number 1 to 100. In grade 2 They study mixed number. For example, What is solution 26 + 4 – . . . = 8 ?. Almost students can not answer this question directly because it is abstract problem. Teacher must change it into real context which is easy for students to understand. In this article, writer introduces Snake and stair (Ular tangga) solution.

Snake and stair game is a game which is played by four students. Each student has a pawn, and he/she gets opportunity to shack cube. Cube has number 1 to 6. A student will put his/her pawn building on number in cub that he/she gets. Student’s cub which stand in stair will climb that stair but in snake will reduce, so they use mathematics process in this game.

I. INTRODUCTION

Everywhere in the world, people know about mathematics and usually use mathematics to get a better life. Mathematics can be found around us and give many positif influences. Sometimes, it appears from small matter, such as estimate of time to go to school until big case as make large buildings which use scaffoding concept. It is really realistic in mathematics and mathematicians said that “It is realistic mathematics.”

Realistic mathematics has been developed for the first time in Netherland. After that, It was adopted into Indonesian context which is introduced as Indonesia Mathematics Realistic Education. In Bahasa, We say “ Pendidikan Matematika Realistik Indonesia”, and it is called as PMRI. It has been developed in Palembang (South Sumatera) since 2004. There are in SDN 98, MIN 1 in 2004 and MIN 2, SDN 117 in 2007.
