this post expressing my frustration with our block schedule when trying to fit in reading and writing, I've found a solution that works for us. Unsurprisingly, it comes courtesy of Kasey Kiehl so rather than trying to summarise what she says so well, here's the link.
I downloaded her free advice pack from TeachersPayTeachers and realised I was not using my time efficiently. Now we've got transitions down to seconds, and we are reading and writing, to some extent, every lesson. An added bonus is that the extra 2 or 3 students I conference with in the reading sessions adds up to a better rotation time between all the students.
If you're struggling with the same issue, I highly recommend exploring the above links.
