What Are the Common Properties of Math Operations The basic properties that are used in math operations are fairly simple. In total, there are four basic properties for real numbers: associative, identity, distributive, and commutative. These properties are only applied to the operations of multiplications and addition. These properties are not in-built in division and subtraction operations. Commutative Property: (a + b = b + a) or (a x b = b x a) The sum or product of two or more real numbers is always the same regardless of the order they are added. Associative Property: (a + b) + c = a + (b + c) or (a x b) x c = a x (b x c) The sum or product of two or more real numbers will always be the same regardless of how they are grouped in an equation. Identity Property: (a + 0 = a) or (a x 1 = a) For addition: Any real number added to zero is equal to the number itself For multiplication: Any real number multiplied to 1 is equal to the number itself Distributive Property (Multiplication over addition): a (b + c) = ab + ac Multiplying a factor to a set of real numbers being added together equals to the sum of the factor of products and every addend in the brackets. These worksheets use a variety of common property of operations to solve a wide variety of different types of math problems.

I have a strong feeling that kids need visual cues at this age. That is reflected here.

These are a bit more advanced to start working on those upper levels of the curriculum.
