My son said was tidiying is the correct answer.
Hi, your son is correct
We use the conjunction 'as' when one event happens while another is in progress (similar to 'when' and 'while'). The verb that follows after the conjunction is often in the continuous form, and therefore we choose 'was tidying'.
