Addition is one of the most basic and essential mathematical operations. It is defined as combining more than one set to create a different number. The sum is not always larger than both the addends because negative numbers can be used in addition equations. The plus sign (+) signifies addition, and it is commutative, meaning the order of the addends does not matter; the sum will still be the same.

VA Standards of Learning

1.5: The student will recall basic addition facts with sums to 18 or less and the corresponding subtraction facts.

Background Information from Curriculum Framework:

• Associate the terms addition, adding, and sum with the concept of joining or combining.

• Provide practice in the use and selection of strategies. Encourage students to develop efficient strategies. Examples of strategies for developing the basic addition and subtraction facts include

– “one-more-than,” “two-more-than” facts;

– “doubles” to recall addition facts (e.g., 2 + 2 =__;

3 + 3 =__); – “near doubles” [e.g., 3 + 4 = (3 + 3) + 1 = __]; – “make-ten” facts (e.g., at least one addend of 8 or

9);

– use of the commutative property, without naming

the property (e.g., 4 +3 is the same as 3 + 4); – use of related facts (e.g., 4 + 3 = 7 , 3 + 4 = 7, 7 –

= 3, and 7 – 3 = 4); – use of the additive identity property (e.g., 4 + 0 =

4), without naming the property but saying, “When you add zero to a number, you always get the original number.”; and

– use patterns to make sums (e.g., 0 + 5 = 5, 1+4=5, 2+3=5,etc.).
