Hi. Am looking for sec1, 2 n 3 students to form small group w my students at toa payoh.


sec1 Fri 2.15 - 3.45pm

Taught by yours truly with >15 years experience
including 10 years (n counting) of teaching in schools.
W the change in syllabus (starting from last year sec
1), I hope to provide students with the learning
experiences that the schools might b lacking in.

Can let us know what kind of learning experiences are the schools lacking in ?

There is basically no change in topics but
New syllabus focus on learning experiences i.e. more hands on, more applications to real life usage of the math concepts. u can take a look at last year's o level papers 2014.
Many students were stumbled because they don't see math outside the classroom.

E.g., I gave my new sec 1 student a physical box n asked her how to find its volume. She was clueless. But when I draw her a box on paper, she is able to tell me length x breadth x height.

dear all, Am looking for sec1, 2 n 3 students to form small group w my students at toa payoh. Currently only 1 student in each level

Michael is an art elective programme student who is working on an assignment. He designs a rectangular pattern measuring 45mm by 42mm. He is required to use identical rectangular patterns to form a square. The maximum area of the square allowed is 1.6 square meters.
(i) How many patterns does he need to form the smallest square?
(ii) What are the dimensions of the largest square that he can form?

Think this way: Lay the tile (pattern) in a straight line,
length-wise:
45 + 45 +45 +45 + ...
This length is effectively multiples of 45.
Then lay the tile (pattern) downwards:
42
+
42
+
42
+
...
This width is effectively multiples of 42.
To be a sq, the length n width need to be the same so
u are looking for a common multiple of 45 n 42.
So the smallest sq formed will have dimensions which is
the lowest common multiple of 45 n 42.

ii) since the lcm of 42 n 45 is 630, that means squares
formed by this pattern will hv length which are
multiples of 630mm.
the largest sq less than 1.6m2 has length sqroot(1.6) =
0.4m
Hence 0.4m / 630mm, take the whole number from the answer
