Dear colleagues - I wonder if you can help me. I've had a KS2 SAT review turned down. The nub is that a sentence written by the pupil was not deemed grammatically correct. The question (KS2 GPS Paper 1 Q19) was: Write a suitable question to fit the answer below. Answer: He is ten years old. The pupil wrote: How old is your sun Ben? The spelling mistake is irrelevant. There is an argument that a comma between sun/son and Ben would improve the sentence but this is optional and verbal intonation could indicate either. Ben could be the ten year old son or Ben could be the person addressed by the questioner. Either seem grammatically correct to me. What do you think?! Thank you.
