Videos, worksheets, stories and songs to help Grade 6 students learn some of the properties of Real Numbers and the Properties of Equality.

Some properties of Real Numbers are:
Associative Property of Addition, a + (b + c) = (a + b) + c
Associative Property of Multiplication, a • (b • c) = (a • b) • c
Commutative Property of Addition, a + b = b + a
Commutative Property of Multiplication, a • b = b • a
Distributive Property, a • (b + c) = a • b + a • c
Additive Identity Property, a + 0 = a
Multiplicative Identity Property, a • 1 = a
Zero Property of Multiplication, a • 0 = 0
Substitution Property, If a = b, then a may be substituted for b, or conversely.

Addition Property of Equality, If a = b, then a + c = b + c.
Subtraction Property of Equality, If a = b, then a - c = b - c.
Multiplication Property of Equality, If a = b, then a • c = b • c.
Division Property of Equality, If a = b, then a / c = b / c, assuming c ≠ 0.
Reflexive Property of Equality, a = a
Symmetric Property of Equality, If a = b, then b = a.
Transitive Property of Equality, If a = b and b = c, then a = c.
