In a decodable or leveled reader, words can be flagged with a colored background. Also, an entire page can get an orange border. A yellow pop-up box appears to explain why the word or sentence is flagged.
This word uses letters that have not yet been introduced.
(Be aware that a word that has too many letters can look similar.)
The number of words is more than the maximum number set for the current level.
An orange border means that there are too many words or unique words on a page for the current level.
