Dragon Curve and Jurassic Park!

Here are two fantastic videos about the Dragon Curve from Numberphile!

The Dragon Curve is a little known fractal that is very beautiful and mysterious. It can be obtained by simply folding a piece of paper!

This video very aptly and clearly describes the Dragon Curve, which can be found in the book of Jurassic Park. (Many people have watched Jurassic Park, but few have read the book, hence the Dragon Curve is unknown to many.)

Legendary Computer Scientist Don Knuth introduces his beautiful "Dragon Curve" sculpture in his home. And also a moral to be learnt: It's ok to make mistakes, just learn from them! "Err and err and err again, but less and less and less." — Piet Hein. How is this quote of wisdom related to the Dragon Curve? Watch the video to find out!

Lastly, just a sneak peek of the upcoming Jurassic World Official Trailer! Jurassic World will be released in 3D by Universal Pictures on June 12, 2015. Excited?

SMU Calculus MATH 001 Tuition

SMU Calculus MATH 001 Tuition

Mr Wu can teach tuition for the SMU Calculus Math 001 module.

Here is a testimonial from one of his previous students (with zero H2 Maths background!):

The previous module mentioned refers to the SMU Calculus Math 001 module. He is now taking the SMU Stat 101 module from SMU.

By the way, the SMU Calculus Math 001 is pretty challenging. It includes multivariable calculus which is something new and not in H2 Mathematics syllabus!

JavaScript XOR Hexadecimal App!

This is a simple JavaScript application that can XOR Hexadecimals (Hex), 2 characters at a time. The output is in 2 digits, meaning that "0" is written as "00".
Hope it helps!

XOR: Exclusive disjunction or exclusive or is a logical operation that outputs true whenever both inputs differ (one is true, the other is false). It is symbolized by infix operator XOR. (Read more at: Wikipedia: XOR)

Hexadecimal: Base 16 numbers, using symbols 0–9 to represent values zero to nine, and A,B,C,D,E,F (or alternatively a–f) to represent values ten to fifteen. (Wikipedia: Hexadecimal)

Input 1:
4546204748

Input 2:
2020202020

For instance, given the input:"abcde12345", separating using the default settings will output:"ab,cd,e1,23,45".
Hope it helps!

Input:

New Topics for Primary 5 Mathematics (P5 Maths)

Singapore Math Review

The transition from Primary 4 Maths to Primary 5 Maths is a significant one. There will be new topics taught, and also most significantly, the introduction of the calculator!

Most students will be overjoyed at being able to use the calculator. Personally, I feel that using the calculator at such a young age may not be so good, as it deprives student of the arithmetic practice necessary for intuition in calculation, and also affects mental calculation skills. For instance, adding 15+27 mentally should be possible for Primary 5 Students.

Other notable new things that Primary 5 Maths include are:

• Fraction Division (a confusing topic for many)
• Area of Triangle
• Volume of Cube and Cuboid
• Angles (More advanced than Primary 4, includes sum of angles in Triangle)

The problem sums would be pitched at a higher level now, since students have the calculator. Knowing how to check answers with the calculator would be a huge advantage. (Many students dislike checking answers, from my experience, although it is one of the most important skills needed to ace primary school math.)

Free Calendar Template for Tuition / School

Are you looking for a Weekly Timetable Template for School / Tuition?

You can download it here: https://mathtuition88.files.wordpress.com/2015/01/weekly-schedule-sunday-to-saturday.pdf

I have chosen the most suitable calendar template from www.calendarpedia.com for Singaporean students to use. I personally use this template to track my tuition schedule too.

Preview: (You are recommended to download the PDF link for greater resolution.)

Nowadays students have a lot of tuition (especially those taking a lot of subjects), hence it may be good to use this calendar to keep track of which tuition is on which day, to avoid confusion. Hope this calendar helps!

This calendar is best used for events that repeat weekly at exactly the same time, e.g. tuition, CCA, swimming lessons, piano lessons, etc.

Math Movie: The Imitation Game

Anyone interested to watch a movie about Math can seriously consider: The Imitation Game.

It is a movie about mathematician Alan Turing, and the role he played in cracking the Enigma code used by the German Nazi during World War II. It has proven to be pivotal in the defeat of Germany in key battles.

I have not watched the movie yet, but the trailer seems really interesting and I will definitely get down to watching it one day.

The movie is released in the USA already (Release Date: 25 December 2014 (USA)), but for some enigmatic (pun intended) reasons it is only being released in Singapore in 22 January 2015.

Hope everyone enjoys the movie!

Maths Tuition for Private Candidates

Maths Tuition for Private Candidates / University Students

I am providing Maths Tuition for Private Candidates who wish to retake their O Levels or A Levels. Also can teach mathematical topics at the undergraduate level, for example Engineering Maths.

Please visit http://mathtuition88.com/ for more details!

You can also email me at mathtuition88@gmail.com.

Timeslots

• Weekdays 11am-1pm

I can most likely teach during weekdays (Mon-Fri) 11am-1pm since most of my tuition students are in school. Do message me to check the available timeslots, thanks!

Students can choose either once a week, or multiple times a week tuition. (Depending on their mathematical foundation.)

Start early for best results

Math is a subject that requires practice, and also time for the concepts to get absorbed. Last minute cramming is unlikely to be of help if the foundation is weak. Hence, starting tuition early would be the best strategy.

The plan will be to get to the level of being able to do past year papers as soon as possible. Then, we will work through past year papers (and prelims if time permits), which is an incredible strategy to practicing O Level Maths / A Level Maths since the questions that will come out will be similar in nature. A student who has done the full Ten Year Series, and is familiar with it, has an overwhelming advantage over someone who hasn't. This is simply due to the fact that some questions will be repeated. (Not exactly, of course, but similar)

Tutoring Scam that targets Tutors

Today I received an email, that is very highly likely to be a scam. According to this website (https://drsaraheaton.wordpress.com/2014/03/12/tutoring-scam-targets-teachers/), another tutor (from Canada) has received the same email. The scam targets teachers (even martial arts teachers from this forum). So beware! The modus operandi seems to be sending a counterfeit cheque with excess value, and asking the tutor to send the "balance" back. Details of email:

O Level Results Release

Source: http://www.moe.gov.sg/education/admissions/jae/

The moment of truth

The 'O' level results will be released (tentatively) between 12 and 16 January 2015. Best of luck for everyone who took the O levels in 2014, including many of my former students. Sincerely wish that the can get the required L1R5 to enter their dream school.

Check out http://mathtuition88.com/2013/10/25/jc-admission-cut-off-points/ to get a rough idea of the cut-off points for JC. Admission is admittedly getting quite competitive, especially for the top few JCs, namely RJC, HCI, and ACJC/ACS(I).

When does JC1 start in 2015?

According to MOE, JC 1 students will start school on 30th January 2015 (Friday). A pretty good start to school, have a weekend break immediately after the first day. The current system is definitely better than the previous system of going to one school based on prelim results, and then waiting an entire 3 months for the results to come out, before entering the final JC.

JC 2 students will start school earlier on 5th January 2015 (Monday).
