However, after pouring the water from one glass onto another taller or wider glass, the children do not perceive that mass stays the same, even though shape changes. At this stage children also begin to categorize;

The concrete operational stage, taking place from seven to 11 years, is characterised by the onset of logic and reasoning. The period is when the cognitive development of the child becomes a drastic improvement from the previous stages. Using the previous test of water in two glasses, this is the stage where the child learns that the mass stays similar, even in another container. They understand the concept of reversibility. Children also learn the concept of seriation: ordering objects according to differences. At the concrete operational stage, children have “no difficulty with the seriation task. The 10 sticks are ordered accurately without trial and error”. They are shown to have grown capable of mentally calculating and sorting three characteristics at once.
