Brain Development in the Pre-K and K Years
During pre-school and Kindergarten, the brain grows steadily, increasing from seventy percent to ninety percent of its eventual adult weight. In addition to gains in size, the brain undergoes considerable reshaping and refining. Among these modifications are profound changes in the frontal lobes-areas of the brain devoted to regulating thought and action. The frontal lobes govern the inhibition of impulse, orderly memory, and the integration of information- capacities that facilitate reasoning and problem solving. All these skills improve considerably in kindergarten children.
