There are two different types of speed reading. This method of speed reading can be useful, and some schools teach it. Using expanded reading, the practical limit to reading speed is about 700 to 900 words per minute.
Some children have peripheral vision good enough to be able to catch a whole page at a glance.
Using the dynamic reading method, the practical limit to reading is over 10,000 words per minute. However, it is more common to have kids end up with reading rates of between 1,500 and 5,000 words per minute. Our manual, Speed Reading 4 Kids, shows how to teach dynamic speed reading to children.
