What do baric tablets measure?

Baric tablets are specifically designed to help children understand and explore the concept of weight. They consist of tablets of different weights that are made to look similar but vary in mass. By handling these tablets, children can physically feel the differences in weight, fostering their sensory awareness and appreciation of the property being measured.

Using baric tablets aligns with Montessori principles, as it encourages hands-on learning and sensory exploration. Children can engage in activities where they compare, contrast, and classify the tablets based on weight, thus gaining a deeper understanding of this physical property.

The other options don't apply because length is measured with linear tools (like rulers), temperature requires thermometers, and color is assessed using visual instruments rather than through tactile interaction, which is the primary focus of baric tablets.
