A Charlotte Mason Moment:
“The power of reading with perfect attention will not be gained by the child who is allowed to moon over his lessons. For this reason, reading lessons must be short; ten minutes or a quarter of an hour of fixed attention is enough for children of the ages we have in view, and a lesson of this length will enable a child to cover two or three pages of his book. The same rule as to the length of a lesson applies to children whose lessons are read to them because they are not yet able to read for themselves.”
