Pupils across England and Wales have faced disruption as members of the National Union of Teachers strike over pay, pension changes and workload.
The Department for Education (DfE) said the NUT was disrupting parents' lives and holding back children's education.
Sally Gould, a maths teacher in Manchester, recorded her daily routine for BBC Radio 5 live's Breakfast ahead of the strike action.
She told the programme, "To be a modern teacher I have to prepare in a week what most managers in an office would prepare in a year."
