This paper-based applet adopts the Java version entitled ‘Beads on Chain’. To access this, you may visit: http://www.fisme.science.uu.nl/toepassingen/00747/

Number pattern, or commonly known as ‘*bilangan loncat’* by the lower grade students in Indonesian primary school, is first taught in the third grade.

The ‘beads on chain’ applet is actually a very good manipulative to stimulate students’ understanding on this concept. However, internet connection which does not support most Indonesian elementary schools has been an undeniable challenge. Therefore, preserving the paper-based version could be an alternative.

I have tried out the ‘Colourful Necklace’ to learn number pattern with a number of Grade III-D students of SD Pusri Palembang.

At first, I invited 2 students to play during the breaktime. Hearing that I would play with them, some other students came closer and got involved. It shows how this tool first impressed and be positively responded by the students.

To begin with, I told them the way to make a colourful necklace. Here, I emphasized that a similar pattern is important to make the necklace more beautiful. So, we first placed two yellow beads, then one brown, then yellow, and then blue again. Next, I tested them for the following sequence to ensure that they understood the problem. Finally, we got the first two sequences of alternating beads colour.

I, then, told them that I would love to use 32 beads for my necklace and I was worried about the colour of the last bead will be. The students were mostly confused and tried to gamble the answers. After a little repeating with emphasis to the questions, several students tried to think.
