Allie is in the concrete operational period, which typically ranges from about 7 to 11 years old. During this stage, children gain a better understanding of the concept of conservation, meaning they recognize that altering an object's appearance does not change its basic properties. Allie's understanding that spreading out the pennies does not change the number of pennies indicates she has grasped this concept, which is characteristic of the concrete operational period.
