Question (a).
Question Pupil answer estimation Calculation
Estimate the total of
472 360+93877+125 883
472000
94000+ 1250001537000
( mistake are made
when they arrange
the number in
wrong place value)
Round off the
numbers to thenearest thousand
472 00094 000
+ 126 000692 000
472 360
93 877+ 125 883692 120
The answer:
a) 692000
b) 692120
Pupils must understand the concept of place value very well before we do any calculation
involving addition, subtraction, multiplication and division.
In this case, pupils can use rounding strategy. Children using the rounding strategy
would round 472 360 to 472 000 and 93 877 to 94 000 and 125 883 to 126 000 and
estimate the total between the numbers as 692 000.
Question Pupil answer Estimation calculation
Subtract 8 507 from
45 739 to the
nearest thousand.
45 000 ─ 8 000
37 000
( pupils makemistake when round
off the number
according their
place value)
Round off the
numbers to the
nearest thousand
46 000 ─ 9 000
37 000
45 739 ─ 8 507
37 232
The answer:a) 37 000
(To round numbers
to the nearest
thousand, make the
numbers whose last
three digits are 001
through 499 into thenext lower number
that ends in 000.)
For second question and third question, pupils can use the front-end strategy. The front-
end strategy focuses on the left-most or highest place-value digits. For example, for

Step 1
(10 minutes)
1. Teacher shows a diagram.
2. Teacher poses a question and pupils listen
carefully.
3. Teacher explains try –to-guess activity:
i) Mother prepares 1 piece of pizza
ii) The pizza divided into 9 small equal parts.
iii) How many ⅔ ÷ 6 = ?
iv) Use a diagram. ⅔ of the diagram is
dividend into 6 small equal parts.
Shade them. So, there are 9 parts
altogether now. Each small part now is
/ˡ 9 of the whole diagram.
v) So, ⅔ ÷ 6 = /ˡ 9.
4. Teacher expresses the activity above using a
number sentence.
⅔ ÷ 6 = /ˡ 9.

1. Teacher prepares 1 cake
like shows pictures
above:
Teacher asks the following questions:
i) How many is the cake?
ii) There is 1 cake. If ½ ÷ 2=?
2. Pupils interpret the number sentences above
and do the activity based on the questions.
3. Teacher show the calculation:
½ ÷ 2 = ½
2= ½ ½˟
= ¼
4. One of the pupils asked to arrange the
situation to form a complete number
sentence.
5. Teacher cut the cake into half. The half cake
put into the refrigerator. The left half of thecake cut into 2 parts. Then teacher compare
the part of cake with a whole another cake
with same size.
6. The answer is ¼ or one quarter.
