You are doing a great job already. As long as you are an engaged and encouraging parent, your child will really benefit. My DH had a similar upbringing and said that he wished he did have more support growing up. MIL didn't value education and wasn't really present or supportive for DH when it came to education or school. He’s even said that he wished his mum cared about his education so with our DC he’s really supportive. I had an opposite upbringing where my immigrant parents raised my brother and I in a supportive manner where education and developing a good work ethic were priorities.
Follow their interests but do not be the pushy parent. Be flexible with your child. Teach them about being well rounded with life skills. It’s not just about being having the best grades. It’s also about being kind and teaching them life skills and people skills that they can use in the future.
Help build their confidence.
Help with school projects and homework.
When it comes to subjects that are tough for them, sit with them to go over it or get a tutor.
Encourage education. Learn new words and build their vocabulary. Get a thesaurus. For every one word, they will learn a few more. A children’s encyclopaedia is good for them to learn facts too. We read the Week Junior and it’s a great publication for kids.
Show interest in their exams or major school events.
Make learning fun. Play games etc..
Praise them for the effort they put into their work. It might not be perfect all the time but it’s about their effort in studying and perseverance with subjects that are tough for them.
Talk to them about everything, while on the school run or during meals etc..
Find out what their interests are and sort out activities and classes to support their interests.
Trips to the library, museums, art galleries, National Trust sites, points of interest etc.. Make a bucket list for each season so you can have activities planned each weekend.
Have a good night time routine for bed time.
Provide a clean uniform and things for school as they need them.
Help them get organised. Put a timetable in their room or in the kitchen. Have an area where they can do school work.
Get involved in school and participate the best you can given your schedule. Meet parents of their friends. Join the PTA. Volunteer when you can. These connections can help you get some insight on what’s happening in school.
Talk to them about their future. Talk to them about the various career paths and what steps it takes to get there. It’s good to pursue passions but talk to them about the realities of cost of living and salaries. If they have interests in a certain field, see if you can get them to have a chat with someone that works in that field. Talk to them about the process of applying for work experiences, internships, jobs etc..
