Question

Piaget's theory suggests that children in the concrete operational stage (usually around ages 7-12) are still developing the ability to reason logically and can only understand concrete, tangible concepts. They struggle with hypothetical or abstract entities such as mathematical variables, which are more commonly taught in higher level mathematics courses. Therefore, it supports the trend that variables appear in most elementary school curriculum in the sixth grade, when children are typically entering the formal operational stage and developing more abstract reasoning skills.
