Videos, worksheets, stories and songs to help Grade 6 students learn about the
addition property of equality and the subtraction property of equality.

The addition and subtraction property of equality states that

the same number may be added (or subtracted) from both sides of an equation without changing the equation's solution i.e.

if a = b then a + c = b + c

(and a - c = b - c)

This property can be used to form equivalent equations and solve equations.
