Read daily. This will be the first task you must address. If you are having trouble with fluency, you need to expose yourself to a variety of reading materials. That means don't just read things you normally read, but include variations that range in difficulty levels. Set time apart in your day that you devote to reading.
Keep a reading journal. A reading journal allows you to be actively engaged with the text. To improve reading fluency, you must engage the text. Don't expect the same results from just participating in reading. In your journal, jot down notes, questions, reactions and difficult words. Write in your journal every other chapter or as you go along. Before you continue your daily reading, look over what you've written.
Determine what you already know about the topic. Educators do this in the classroom. If you are improving your reading fluency alone, repeat this practice. Connect what you're reading to real life. Anticipate what you expect from the reading and from the author.
Manipulate the text. Highlight, underline, sticky or tab your reading book. This is a part of active engagement. Then consider the text itself. Look for themes, patterns, structure and types or reasoning. When you read, you want to have familiarized yourself with these terms.
Build your vocabulary. This greatly improves your reading fluency. That is why it is necessary to read an array of materials that presents varying difficulty levels. Keep a dictionary on hand to define unknown terms.
