Equality and Inequality
Equality is not just a mathematical notation — it is a concept of balance. Before students ever see an equals sign, they should understand 'the same as' through physical experience with a pan balance. Placing objects on both sides and watching which way it tips (or stays level) gives the deepest possible preparation for algebraic thinking. A student who truly understands equality as balance will never confuse '=' with 'the answer is.'
