Primary Balance

Our improved, easy-to-use balance that helps younger students discover the meaning of mass through hands-on investigation.

The Primary Balance allows young learners to compare, predict, and test the mass of everyday objects while developing a concrete understanding of balance, equality, and measurement.

About the math:
• Compare the mass of counters and objects through direct investigation
• Explore concepts including heavier, lighter, equal, and balance
• Develop early measurement, estimation, and scientific inquiry skills
• Introduce foundational concepts that support algebraic reasoning and equations
• Encourage observation, prediction, and evidence-based thinking

The oversized recessed pans keep objects securely in place while students experiment, and the quadrant markings make it easy to observe and discuss how the balance changes. Independent balance adjustments on each side create additional opportunities for exploration and discussion.

• Heavy-duty plastic construction for years of classroom use
• Easy to clean and maintain
• Simple two-piece assembly
• 12-inch balance beam with two recessed pans
• Compensator clips allow quick and accurate calibration

Perfect for whole group lessons, math centers, STEM projects, science investigations, and small-group instruction.

Help students move beyond simply measuring objects to understanding why they balance, compare, and relate—building the conceptual foundations for measurement, equality, and mathematical reasoning.
