Can I change the age range after starting a story?

No, and that is deliberate. A book whose chapters change reading level halfway through stops working as a book. Start a new story in the band you want; nothing stops you having one going in each.

What if my child is nine but reads like a six year old?

Use the 6-8 band. These are reading levels with ages written on them because that is what people search for. Nothing on the page says which band a story is in, so there is nothing for a child to feel self conscious about.

Which band should I use if we are reading it aloud?

Pick for listening rather than reading. A child can follow a story a year or two beyond what they can comfortably decode themselves, so if you are doing the reading you can usually go a band higher than you would otherwise.

Choosing the right age range for your story

It is a reading level with an age written on it. How to pick the one that fits the child in front of you, and why it stays fixed per story.

The age range is the only setting in Taleium that changes the writing itself. Everything else is about the story; this is about the sentences.

It is worth thirty seconds of thought before you start a book, because it stays with that book.

What each band actually changes

Ages 3-5. Chapters of 150 to 250 words. One idea a sentence, familiar words, phrases repeated so a child can join in, and nothing frightening left unresolved when the chapter ends.

Ages 6-8. Chapters of 250 to 400 words. Full scenes with dialogue, new words used in a way that explains them, and a small problem solved each chapter.

Ages 9-12. Chapters of 400 to 600 words. Description that does work rather than filling space, characters who want different things, and chapters that end somewhere the next one has to pick up.

Those are not three lengths of the same writing. A chapter for a four year old and a chapter for an eleven year old are constructed differently, and the difference shows up in the first line.

Pick for the child, not the birthday

The bands are named after ages because that is what a parent types into a search box at seven in the evening. They are really reading levels.

If a nine year old finds reading hard, the 6-8 band will give you a much better evening than the 9-12 one will. If a six year old is tearing through chapter books, go up. Nothing anywhere on the page announces which band a story is in, so there is nothing for anybody to be self conscious about.

A useful test: read the first chapter aloud and watch their face during it. If they are ahead of you, go up a band on the next book. If they have gone, drop one.

Reading aloud changes the answer

A child can follow a story a good year or two beyond what they can comfortably decode on their own. That gap is the reason reading aloud to a confident reader is still worth doing.

So if you are doing the reading, or if you are using the read aloud button, you can usually pick a band higher than you would if they were reading it themselves. If they are going to read it alone in the morning, pick for that instead.

Why it is fixed once the story starts

Because a book that shifts reading level between chapters stops being a book. Chapter twelve has to sound like chapter one, or a child reading back through it notices that something has gone wrong without being able to say what.

If a band turns out to be wrong, the answer is a new story rather than a patched one. Stories are quick to start: a title, a band and one sentence about what happens first.

Two bands at once is fine

If you have two children a few years apart, run a story in each. The cast of characters is shared across all your stories, so the same fox can be in the 3-5 story and the 9-12 one, behaving the same way in both and simply being described at different lengths.

That is usually a better arrangement than one story pitched in the middle, which tends to be slightly wrong for both of them.
