• Questions to address:
– Do we have evidence of growth?
: Mum, I got 80 marks in my math!
: Wow! How about the others?
: M…m about 98, 99… 95 in general.
: What?! You must work harder!!!

: Mum, I got 98 marks in my math!

: That’s my good boy! …
Who got the highest mark?
Son : M…m John did. He’s 200 & that’s the max.
Mum : What?! You must work harder!!!
– What is the rate of growth of this student?
– Is the rate of growth of this student
comparable to an average student of
similar background?
– Will this rate of growth lead to reaching the
standard in due course?

Metacognition
Ability to Articulate Learning Strategies
I succeeded because I revised according
to plan. During test, I read the items
seriously and carefully; I responded
clearly and strategically; when I met with
items that I did not know how to answer, I
tried my best to answer; I seriously
checked the script and modified my
response to get the correct answer.
I failed because I have not mastered
revision skills; haven’t remembered
the main points so that my results
were very poor. Further, I did not
study in a quiet environment and I
was too nervous at the time so that I
did not reach my full potential.

Why do you think this is the case? You
may choose more than one option.
 The mass of liquid displayed is the
same as the mass of the ice.
 The volume of liquid displayed is the
same as the volume of the ice.
 The volume of ice is larger than the
volume of liquid .
 The density of liquid is higher than
the density of ice.
 The temperature of liquid is higher
than the temperature of ice.

A bee farmer wants to know
how many bees there are in one
of the beehives. He took out 200
bees and label each of them
with a tag. He put the tagged
bees back in the beehive.
Next day he took out 250 bees in a random
manner, and found that 25 of them were tagged.
1. How many bees did the
farmer tag?
2. How many bees did the
farmer catch in total?
3. Estimate how many bees
were in the beehive?
4. Explain how you made
your estimate.

There are 4 bags that each carries 3 books. Each book weighs 20 g.
What is the fraction that best represents
the shaded parts in the figure?
Mary took out all the books from the bags and put the books in a box
which weights 50 g. How heavy is the box now?

A. 60 g
(3 x 20 g)
B. 80 g

During the holidays, I read 18 books. My sister read 3 times as many
books as I did. My brother read 26 more books than the total of what my
sister and I read. How many books did my brother read?
What is the fraction that best
represents the shaded part in the
figure?
 Each part must
be equal in size
(a) 4/8
 Proper fraction

 Each part must
be equal in size
 Proper fraction
(c) 4
(d) 8
Shaded part
1.4/8 is not proper fraction. After
simplifying 4/8 &½ are the same.
2. The parts are not equal in size.
3. 1/2 is the answer. No need to consider 4/8.
Learning Goal: read and highlight all relevant information
4. Will not consider 4 or 8 because they are whole numbers (and not fractions).

At first, I was skeptical about my child being asked
to write journals. After 2 years, I saw major changes
in him. Now I understand and hope other parents
can understand too. Now I can see writing journals:
Is a way to develop his thinking
Is a form of training in writing
Enables the teacher to adjust her teaching
Gives a platform for teacher-child communication
Can consolidate learning
Helps my child to have early reflections upon his
learning errors
Is a basic training
