Control of Error
Variations and Extensions
- A variation could be made to allow for paired matching or grading by weight (see Make Your Own below).
Material
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.
- (For a detailed description of how this was done, see Little Schoolhouse in the Suburbs.)
