FOBISIA Online Maths Challenge Success

FOBISIA Online Maths Challenge Success

In the two-week period before the half-term break students from Years 5 to 9 were invited to complete an online Maths challenge hosted by the Seoul Foreign School. Challenges were set at three different levels – Bronze, Silver and Gold, and at the lower levels multiple attempts were allowed.

As you would expect, the questions were … challenging! They took some figuring out and, as so often happens, multiple lines of attack may have been needed before the “A-ha!” moment of recognition.

Here’s a nice little example of one such question:

Justin Bieber has just revealed that his real name isn’t Justin! However, it is known that he always tells the truth on Wednesdays and Thursdays, he always tells lies on Mondays and on all other days he tells the truth or lies on a random basis. For seven consecutive days he was asked what his name was, and the first six answers he gave were:
“John”, “Brandon”, “John”, “Brandon”, “Sam”, “Brandon”. What is his real name?

The following students successfully completed the Bronze Challenge:

Alson (5K) and Pik Yen (6K)
Jatin, Yvonne, Amos, Debbie, Calista and Zack (all 7K)
Toby and Diego (7S)
Ryan (9S)

The following students successfully completed the Silver Challenge:

Amos and Debbie
Ryan

And Ryan successfully completed the Gold Challenge as well!

In addition to the individual challenges, there was also a group challenge for which students had to produce a mathematical video. Our Year 9 students produced a very nice short movie showing simple statistical measures, and this may well form the basis of a video challenge of our own later in the year. Year 5 and 6 also worked on this group challenge. Four groups submitted excellent videos but only one could be chosen, and this was the one made by Pik Yen, Anny and Sunny from Year 6. They did an excellent job of showing Maths in everyday life.

Well done to these students, and well done to all the students who took part.
