Use a balance scale to investigate when two different collections have equal value.

🎮 Try It
Place object tiles on either pan in Basics and watch the totals and beam. In Lab, add variable and +1 or −1 tiles, then change each variable’s value. Save snapshots to compare different balanced arrangements.

🎯 Your Mission
Create a balanced Lab arrangement whose two pans do not contain the same tiles. Change one variable, observe what breaks, then restore equality without clearing the scale.

🌍 Real-World Connection
A two-pan scale balances when both sides have equal weight, just as both sides of an equation must stay equal.
