Ash 202. Please take a step back. Remember that your child has already done a six hour day at school and might have some expected school homework some nights a week. To then add on a pile of extra work books is a good way to put them off the joy and pleasure of reading and learning.
My advice to you is simple,
join a local library and make it a habit to go there every week to borrow a range of books (fiction, poetry, information, graphic novels, play scripts, fairy stories, old favourites, new authors, picture books), both for you and your child to read together and for her to enjoy reading on her own. Talk about the books/ characters/ how the books make her feel.
next encourage your child to have outside interests, join her up to brownies, or a sport she likes, a drama class, anything that involves learning physical or non academic skills.
teach her to ride a bike, swim, roller skate, skip, kick a football, throw over arm.
lastly take your child to interesting places and extend her curiosity , even simple trips to the park can be used to identify trees, plants, birds you hear. Talk to your child, watch tv with them and talk about what you are watching.
Use these years to parent a curious, articulate, confident child. Your child may pass the 11+ , or might not, but whatever school she ends up at it is character, perseverance, curiosity and love of learning which are the soft skills that will stand her in good stead.
