7 INSPIRING CLASSROOM ACTIVITIES USING

REALISTIC MATHEMATICSComposed by : Ratih Ayu Apsari

The content is summarized from seven articles of National Conference of Mathematics XIV

(2008), Sriwijaya UniversityThis presentation is made to accomplish the assessment of ICT in

Mathematics Education course by Prof. Dr. Zulkardi, M.I.Komp., M.Sc.

[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.

[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.

[2] Ariyadi Wijaya : Indonesian Traditional Games in Learning Measurement of Length

All players in each team have to hit a short stick andthen the distance of the fallen stick is measured. The

winner determined by the team which has the longerdistance of the stick.

Students are free to choose measure-ment tools either the unit which use to

compare the length of distance. Theconjecture for this activity is the students,

while measure the distance of their stick,may use different tool and unit, such astheir footsteps. It will lead them to

different result since every students havedifferent size of step.

From this situation, they willrealize that they need to use

same measurement to obtainsame result for same distance.

This basic concept can be usedas the first step in introducethe standard measurement

for the students.

[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?

[6] Puspita Sari : Empty Number Line Model in The Addition and Subtraction Learning

The empty number line could be
