@Mummame2222 I've been a primary teacher for 14 years in KS2. I now work 2.5 days, and in that time I'm in school for 27 hours (I go in on my half day unpaid so I can get my some of my marking done). Things I have to do outside those 27 hours/school hours:
Marking
Planning
Resources
A form after every lesson noting down children who need extra help, notes for next lesson etc.
Plans for children with EHCPs and SAPs (school action plans).
A meeting once a week til 5pm.
A singing club (I choose to do this voluntarily)
Paperwork linked to my subject (primary teachers are required to lead a subject. The paperwork workload for this is huge thanks to Ofsted)
Training courses (child protection, online safety etc). These are online now, but can be quite long. The child protection one was nearly 2 hours. Understandable, as it's so important.
Fill out safeguarding forms if needed. This is becoming more common unfortunately.
Liaise with social workers if a child with one as an important meeting coming up.
Pupil premium and SEN profiles every term.
Curriculum reviews at various points in the year.
Updating planning (lots of people think we can reuse everything. We can to an extent, but the needs of the children may be different the following year, the govt changes goalposts constantly etc).
Assessments
In summer term, write reports
Plan separately for 2 children in my class who can't access the Y3 curriculum.
Parents evenings (4 throughout the year, so not too many luckily)
Productions (two evenings)
I also have 2 kids of my own, so life is busy!
In the holidays I try not to do too much work, but I always put the kids in childcare for at least a day or two (depending on the holiday. More in the summer) so I can get some bits done.
I couldn't do it full time and look after my children. I'd never see them!
