CTET Paper II (Social Science) 3 Jan 2022 Solved Paper

Concept:Piaget's cognitive development has four stages. Seriation—arranging objects in order—appears in the concrete operational stage.Explanation:Children gain seriation ability around ages 7 to 11 years. This is the concrete operational stage.
