Any other answer 0.
17 Mathematics Award 1 mark if they write False(F)
Any other answer 0
18 Mathematics Award 1 mark if they write that her answer is wrong and gives a
reason that in step 3, division should have been done before
subtraction as per BODMAS.
Award 0.5 marks if they answer only correct or wrong and do not
give reason 21
Any other answer 0
19 Mathematics One mark each if i) Writes the expression for the number of books
each of them have arranged as (3 × 8) or (8 × 3). ii) Writes that
they have arranged the same number of books and gives a valid
reason. For example, multiplication is closed under commutativity
and hence, (3 × 8) = (8 × 3). i) 0.5 mark for Kiara is (3 x 8) and 0.25
mark for Hania is also (3 x 8) or 0.25 mark if Kiara (8 x 3) and 0.5
mark if Hania is (8 x 3) totaling to 0.75 and ii) one mark if student
writes that they have arranged the same number of books and
gives a valid reason. For example, multiplication is closed under
commutativity and hence, (3 × 8) = (8 × 3).
