Baric Cylinders are found within the Sensorial area of the Montessori classroom. The materials further develop the haptic sense, in this case, weight.

The Baric Cylinders Lesson: Presentation I
- Prepare the box ahead of time with only the heaviest and lightest pairs.
- Invite the child to do the work.
- Ask the child: “Would you like me to show you the baric cylinders? These are the baric cylinders. Baric means weight.”
- Place the box in the center of the mat.
- Remove cylinder with 3-finger grip.
- Arrange cylinders randomly in a line from left to right.
- Start with the left cylinder, carefully lift it and place it in the palm of your hand.
- “Would you like to feel how heavy this one is?” Return the cylinder back in line.
- “Now let’s see if we can find a match. I am going to use my hand to do this work.”
- Isolate the left cylinder, feel the weight
- Weigh each remaining cylinder until you find a match. Move out of line slightly. Weigh the control again, move match to the side. Weigh control, weigh match. “These two match. They are a pair.”
