Ex teacher here, who agrees with all of the other teachers.
There are so many other opportunities for a child to read to you that isn’t a reading scheme book for just 10-15 minutes a day.
Let them help write your shopping list, and they can read it back as you do your shopping (even online for delivery, encourage them to write the list & read it back as you search & order).
Having a takeaway? Let them read the menu aloud as you choose your meal, whether it’s the local Chinese menu at home or the jumbo screens in McDonalds.
Watching TV? Turn the sound off & have them read the subtitles; even better if they do character voices, have fun with it!
What about your child writing their own story & reading it aloud as you cook their dinner?
Or having them read the ingredients & instructions from a recipe as you follow it together?
How about they find a news story of the day online that interests them & is appropriate of course, BBC Newsround is great) and they read that to you & you can discuss together afterwards?
With the greatest of respect, many of us have worked when our children were at school and have still squeezed in 15 minutes of reading. And as much as I’d have loved to sit & hear every KS2 child in my class read every day and discuss the texts, there simply isn’t enough time in the day.
As a teacher, I couldn’t have given a shiny sausage if that 15 minutes of reading was from a school’s reading scheme book, a library book, a religious text or a bunch of till receipts from Morrisons. A few minutes of positive, 1-2-1 communication by a parent, focussed on them alone, makes all the difference, not only in terms of reading ability, but a whole host of psychological & pedagogical milestones too.
