My son's answer was for (b)

Group M is the group with things made out of two more materials.

T put 1 mark instead of 2 marks.

What does need to write?

Do you mind take another clearer pic or maybe to type out the question and your DS's answer? The shot is a bit blur.

Hi smartmummy,

Your child’s answer is :
Group M is the group with things made out of one or more materials (then teacher’s arrow).

So I guess the teacher is looking for :-
Group M is the group of things made out of one or more materials while Ping Pong Ball is made out of only one material.

My suggested (but lenghty) answer would be:
The items are grouped according to the number of materials they are made out of. The things in Group M is made out of one or more materials while Ping Pong ball is made out of only one material. Therefore, it is grouped wrongly.

Hope to see other’s verification on my suggested answers.

Thank you.

Thanks teh_oh for ur kind attention.
My son hate to write lengthy answer.He said T advised don't write so lengthy u might get wrong.It happend to him for the first exam.He wrote the correct answer and he wrote some extra unnessasarily.Then he got wrong and got 0 mark for that qn.I told him If need then u have to be write the full answer.Very difficult to convince him.He always prefer to write short answers.

Hi Smartmummy,

Although your son does not like to write long answers, he must at least learn to compare. An addition to his answer can be 'Group M is ... ... materials, unlike the other group which contains things made up of only one material.' Comparison is a key process skill and often students will be penalised if they did not compare.

Hope it helps!

Hi smartmummy and teh_oh,

Apologies, I did not see the question clearly. Yes, teh_oh you are right. Smartmummy, in educational lingo, your son is not answering to the question. Your son should have provided an explanation to why Group M was the wrong group and compared it to the correct group, which contains items made of one material. Hope this is clearer.
