Learning is a journey, not a race
This is my first time learning for IGCSE. My old school didn’t use the IGCSE curriculum, they had their own curriculum. When I first entered, I thought IGCSE would be just like any other test but boi was I wrong. Being here and learning for IGCSE for 6 months now, I realize that it’s much very serious. The many subject choices just makes it way harder to choose which subject I would dedicated my utmost time studying for. It’s been a hectic and stressful 6 months filled with last minute homework and projects and procrastination. I thank Mr.Kichan for teaching us and helping us prepare for our mathematics IGCSE.
For this semester’s assignment, we had 3 tasks that we had to do to develop our inquiry skills. First, we had this airplane railroad thingy (sorry, can’t explain, just see later) and then we had 2 magic triangles questions. At first I thought that these questions were just a hassle but they were actually quite fun to do when discussing with a partner!!
AIRPLANES AIRPLANES ✈️
So how does this work? Pretend that the overlay picture is an airplane railroad. We’re supposed to find the equation line so the airplane can land perfect so no lives are lost. Equations that are off from the road will crash and the passengers will die. In this question, the topics included are gradient / slope, linear equation, x and y intercepts and graphing equations.
So first what I did here is the y-intercept. I then put the y-intercept coordinate which is (0,-2) into the equation y=mx+b. I then checked the graph for another point and used the formula y2-y1 divided by x2-x1 to find the slope and then plugged in the slope into the equation.
This is another example. I first check the y-intercept (the point that sticks to the y axis) which is (0,11). Then afterwards i find another point which is (1,7). I used the formula to find the slope which is y2-y1 divided by x2-x1. This gets me 11-7/0-1 which is -4. Then i just plugged everything into the y=mx+b formula. The -4 is the m (gradient / slope) and the 11 is the y-intercept. This gives us y=-4x+11.
Our task was to solve the question in the image below: to explore and find out the perimeter and area of the magical Koch’s snowflake triangles. Topics in use is 2D shape perimeter and area formulas (but way more complicated than those 2nd grade 2D shapes formulas kay).
Perimeter of the triangles
Areas of the weird triangles
ANOTHER WEIRD TRIANGLE 🤦🏻♀️ IM SO TIRED 😭😭😭
Our task was to solve all the 6 questions in the picture below of the Sierpinski’s weird and confusing triangles by exploring. Topics in use are the law of indices, 2D shape triangle area formula, ratio, etc.
Construct the next iteration and fill the table (above)
What are the patterns?
What do they have that are in common with each other?
Form a conjecture to obtain the numbers if you were to expand the table further to stage 4, 5 and 6 *sigh*
How would you compare the set of numbers collected?
I double checked the internet for answers to the weird triangles and discussed with my friends uwu so yeah.
Reflective: I reflect back on my working and double check. I reflect on my mistakes and try to not repeat it again next time and learn from the mistake so I can do a better performance next time and progress.
Inquirers: I let my curiosity wander and inquiry and research and explore on how to solve the questions. At first, I learn independently and then discuss with others. I learn with enthusiasm and sustain my love of learning throughout life.
Knowledgeable: I develop and use conceptual understanding that I have learned in the past, explore new knowledge formulas and techniques.
Thinkers: I use critical and creative thinking skills to analyse and take solve complex problems. I make well thought out calculations to avoid silly mistakes.
Communicators: I express my thoughts confidently and creatively during discussions with others. I collaborate effectively, listening carefully to the perspectives of other student opinions.
The first amazing test was very memorable 😂😂 mostly because i died on that day. After a long month of vacation and holiday and jetlag, we immediately go to school and faced the monstrous atrocity called The Amazing Test. It was my first time doing IGCSE so I didn’t know that we couldn’t use a correction tape. It said “no correction fluid” on the instruction page so I thought correction tape was allowed TwT. Ahhhh skskskskskskksksk anyways, lost so much points because of that sigh. I’m so sed.
From here is when the headache finally ends. YAYY WE MADE IT!(=´∀｀)人(´∀｀=)
