how to stretch a child's attention span.. any more inputs, anyone?

Stretch your child's attention span.

Encouraging attentive (nonhyperactive) behavior is the key to preparing your child for school. Increased attention span and persistence with tasks can be taught at home. Don't wait until your child is of school age and expect the teacher to change him. By age 5 he needs at least a 25-minute attention span to perform adequately in school.

Set aside several brief periods each day to teach your child listening skills by reading to him. Start with picture books, and gradually progress to reading stories. Coloring pictures can be encouraged and praised. Teach games to your child, gradually increasing the difficulty by starting with building blocks and progressing to puzzles, dominoes, card games, and dice games. Matching pictures is an excellent way to build your child's memory and concentration span. Later, consequence games such as checkers or tic-tac- toe can be introduced. When your child becomes restless, stop and return for another session later. Praise your child for attentive behavior. This process is slow but invaluable in preparing your child for school.
