that it's 10 minutes of face to face time and doesn't include movement from classroom to working space. You'd end up with about 5 minutes or less if transit time is included.
For reading intervention you might try the writing element of reading recovery lessons a few times a week. In a booklet made of blank pages, the child writes one self-created sentence with teacher support for letter sound correspondence, letter formation, grammar, quick writing of known/sight words, etc. The teacher then prints the sentence by hand on a narrow strip of paper and cuts to separate the individual words. Sometimes cutting apart also on set & rime or plural or possessive markers and prefix/suffix and work on their meanings for older students. Then the student reassembles the sentence and reads it aloud.

It's on the second page of the above. The "short story" is a single sentence (Australian concept of a short story??!!).
This breaks down reading and writing to individual components and then reassembles it into a meaningful context.
The detailed how to for this can be found in Literacy Lessons Designed for Individuals, hopefully you can find one in a library or through interlibrary loan rather than spring for the full price.
