MATH Words first graders need to know:
1. Part-Part-Whole: When numbers are broken into parts. For example, the number 7 (the whole) can be broken into parts of three and four.
2. Symbol: Something that represents an idea. Examples: +, -, <, >. =, $
3. Plus: (+) The symbol used to represent addition
4. Equals: (=) The symbol used to represent equality on both sides of the sign
5. Addends: Numbers that are being added. Example: In the expression 3 + 2 = 5, 3 and 2 are addends.
6. Sum: The answer to an addition problem. Example: In the expression 3 + 2 = 5, 5 is the sum.
7. Count on: This is one addition strategy. Students are encouraged to look at the big number in an addition problem and count on. For example, given 6 + 2, students would say the 6 and count up two more ( 7, 8).
Students use the reverse strategy (Count back) for subtraction.
8. Difference: The answer to a subtraction problem. Example: In the expression 5 - 3 = 2, 2 is the difference.
