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
introduced through a string of beads which alternate in colour for
every ten of it.
