Points of Interest

Control of Error

  • Many commercial baric tablets are made of different woods which have very different specific weights. Being of different colors and appearance (think pine, beech, oak, balsa, mahogany...), the baric activity is done with eyes closed, and control of error with eyes open.
  • The tablets, or other materials used for this activity, can be marked in the back in case they have the same appearance. Thus, once they have been paired or sorted, the child can confirm visually.
  • Also, a balance can be used.

Variations and Extensions

  • A variation could be made to allow for paired matching or grading by weight (see Make Your Own below).
  • balance


The baric tablets consist of two or three types of wooden tablets. These are all the same size and shape, but because they are made of different types of wood, they have different densities and so, different weights.

Make Your Own

  • This is a baric matching activity made with painted baby-food jars filled with different numbers of pennies. These could also be used for grading by using just half (one color) of the set.
