In which stage of Piaget's learning stages is Jenny, who uses manipulatives in math class?

Jenny's use of manipulatives in math class is indicative of the Concrete Operational stage of Piaget's learning theory. In this stage, typically ranging from ages 7 to 11, children begin to think logically about concrete events. They can understand the concept of conservation (the idea that quantity remains the same despite changes in shape or arrangement) and perform operations mentally rather than intuitively.

Manipulatives—such as blocks, counters, or other physical objects—are commonly used during this stage to help students grasp mathematical concepts through hands-on experience. In contrast, the Preoperational stage, which is the choice indicated, is characterized by symbolic thinking but lacks the ability to perform operations mentally or understand abstract concepts. Children in the Preoperational stage might engage in imaginative play and use symbols but are not yet able to logically manipulate structures or think about the outcomes of their actions systematically, which is essential when using manipulatives effectively in math.

Thus, Jenny's engagement with manipulatives demonstrates her capacity for concrete operational thought, enhancing her understanding of mathematics through direct interaction with physical objects.
