One of the very-closed mathematical concepts to us is percentage, of which the idea is represented in such common forms as discount, interest in bank, battery, polling result, and some other social activities. This familiarity would be a great potential to bridge students to learn the concept using PMRI (Pendidikan Matematika Realistik Indonesia) learning approach.
Therefore with, my friend and I have tried to design a set of activities to encourage students’ understanding regarding the concept. The design has been tried out to Grade V-E students of SD Pusri Palembang.
The first activity was conducted to identify how closed the concept of percentage to students is. To begin with, we showed a tagged paper ‘50%’ and asked the students where they use to meet such writing. Almost all the students answered ‘discount’. Several other answers like ‘battery’ and ‘polling result’ was also mentioned.
