7 Inspiring Classroom Activities Using Realistic Mathematics

1. 1. 7 INSPIRING CLASSROOM ACTIVITIES USING REALISTIC MATHEMATICS Composed by : Ratih Ayu Apsari The content is summarized from seven articles of National Conference of Mathematics XIV (2008), Sriwijaya University This presentation is made to accomplish the assessment of ICT in Mathematics Education course by Prof. Dr. Zulkardi, M.I.Komp., M.Sc.
2. 2. [1] Al Jupri : Supermarket Context in Learning Estimation Problems Daily life questions: are there enough?, could this be correct?, and approximately how much is it?. Students are learn to solve this kind of problem by estimation calculation, because most problems in reality are usually appear in the number which is difficult to deal with exact calculation.
3. 3. [2] Ariyadi Wijaya : Indonesian Traditional Games in Learning Measurement of Length The idea behind applied the gundu game is to emerge the concept of indirect comparison. In this game, each player should throw their marbles from starting point to a pole on the ground. The winner determined by compare the distance of the marbles from the pole.
4. 4. [2] Ariyadi Wijaya : Indonesian Traditional Games in Learning Measurement of Length All players in each team have to hit a short stick and then the distance of the fallen stick is measured. The winner determined by the team which has the longer distance of the stick. Students are free to choose measure- ment tools either the unit which use to compare the length of distance. The conjecture for this activity is the students, while measure the distance of their stick, may use different tool and unit, such as their footsteps. It will lead them to different result since every students have different size of step. From this situation, they will realize that they need to use same measurement to obtain same result for same distance. This basic concept can be used as the first step in introduce the standard measurement for the students.
5. 5. [3] D.N. Handayani: Butterfly-Wing Context to Support The Earlier Development of Number Sense The beginner students often not realize the aim of counting.
6. 6. [4] Mellasari : The Context of Structured Candy on Counting CandiesTheCounting

8. 8. [5] Neni Mariana : School Building Context to Develop Spatial Ability The goal of this activity is the children are able to localize for main buildings of the school on a grid paper. This activity use several cube with same size. Activity 1: My School Building Through this activity, children are expected to gradually emerge 2-dimension scale model. Activity 2: Where Our Classroom? The purpose of this activity is to make sure that children are able to: (a) localize all rooms by making a map of the basements on a grid paper, and (b) connect between 3D constructions and 2D shapes of their basements. Activity 3: Removable Buildings The goal for this activity is the students are able to spatially explain routes to some important places using directions, such as to the left, straight ahead, to the right, and so forth. Activity 4: Make a Route to an Important Place in the School The aim for this activity is to help the students to denote one-to-one correspondence between a certain point of standing viewer and a certain point of a part of the school buildings. Activity 5: A Mini Lesson – Where Do You Have to Stand?
9. 9. [6] Puspita Sari: Empty Number Line Model in The Addition and Subtraction Learning The empty number line could be introduced through a string of beads which alternate in colour for every ten of it.
10. 10. [7] Rooselyna Ekawati : ‘Lapis’ Cake Problem as The Contextual Situation in Learning Fraction using fold paper strategy using rubber band strategy
