MYP3 Mathematicians Helping Others Understand Curves

Before I introduce three fabulous websites, I'd like to say that ALL of the MYP3 mathematicians have produced wonderful work demonstrating their understanding of curves and their transformations. Mathsland is proud to call them all citizens.

In our unit we were focusing on linear functions y=mx+p, and dipping into some quadratics but some decided they would like to go further and investigate other curves.

We had linear, quadratic, square root, Archimedes Spiral, sinusoidal and exponential curves. It was busy in Mathsland because everyone had different questions and a different adventure.

Three students, Annalis, Chanya and Eugene (alphabetical order chosen there), created websites using skills taught to them by the much beloved and missed Ajarn Marcus. By creating websites they are providing a service to other learners in the world of mathematics that want to know about sinusoidal waves and exponential functions.

Students used the desmos.com/calculator and its groovy sliders to play around with parameters to spot patterns.
check out some sliders here

Now for the websites:

Annalis' Exponentials are Cool



Eugene's Vas Are Sinusoidal Waves


Chanya's Parabolas

The Weather and its Patterns can be COOL

Below is an animated gif of winds around the Earth.
Check out the key below for deeper understanding of what you are looking at.

A 3-D animated image of Reanalysis-2 data for the first ten days of July 1979, in six-hourly intervals. This animation shows a constant 100mph wind speed surface in red. (Note the stronger, more widespread, polar jet stream in the southern hemisphere--this is July, during the southern winter.) A cyan-colored, constant temperature sheet of zero degrees Celsius ripples across the globe, showing the freezing level. Near-surface wind flow is denoted by white flowlines. This image was generated with plots from Unidata's Integrated Data Viewer (IDV) combined with ImageMagick.


Mean Sea Surface Temperatures


A plot of global, monthly mean wind speeds and directions for September 1990. These data are from the Blended Sea Winds dataset, available through NOMADS. This image was produced with NASA’s Panoply visualization tool.

Here is a cool gif relating to what we are investigating in science and mathematics in MYP2

Mathematical Dance Moves - What's yours?

On the windows of Mathsland are some formulas (formulae) to dance moves - check them out. What's your signature move? How would you graph it?

In MYP3 and MYP5 we have looked at graphing and patterns (different ones). Learning their signature moves on the axes can help us to understand how to graph them but also what they are trying to tell us about the pattern they represent.

Here's my  "squared triple circle cubed undefined gradient dance"



Play around with the formulas in the Desmos Calculator and check out some of the graphs other people have made like the minion...

We Are Happy - AS A TOKEN OF GRATITUDE TO PHARRELL WILLIAMS

This came across my social media world today:

"AS A TOKEN OF GRATITUDE TO PHARRELL WILLIAMS, WE ARE FROM L.A. - CLÉMENT DUROU & PIERRE DUPAQUIER, FOR THEIR WORLDWIDE CONTAGIOUS HAPPINESS..."



We Are Happy Map of Videos - a map is a graph - enjoy!

Here's the one we looked at

Pixels and the Scale of our Solar System

Check out this very cool If the Moon were the Size of a Pixel site, by Josh Worth.

It is very good at communicating the scale of the sun and the distance between planets.

Coordinate Practice - Learning from Mistakes

Ever struggled with plotting co-ordinates?  (x, y) 

On printed maps they use LETTERS with numbers help people locate things. 
What can you find in F6?




In maths, science, Google maps [what is found at location (8.0502489, 98.3523413)] and other subjects that use graphs like humanities, you can't use the same system of letters and numbers. There are always two numbers and you must remember the order. That's the reason coordinates are also called ordered pairs, because the order is important.  (3, 7) is not the same position as (7, 3).

There's "through the door and up the stairs" to help or play these two games and learn by making mistakes. 


Try Billy the Bug and the Whack a Mole game
Billy only has positive numbers.
