Standards with the same topic and subject but for other grades
Identify the rule in a single-operation numerical pattern found in a list or table, limited to addition, subtraction, and multiplication of whole numbers.
Describe the concept of a variable (presented as boxes, letters, or other symbols) as a representation of an unknown quantity. (a)
Identify the equal symbol (=) as the symbol used to indicate that the values on either side are equal.
Write an equation to represent the relationship between equivalent mathematical expressions (e.g., 4 x 3 = 2 x 6; 10 + 8 = 36 ÷ 2; 12 x 4 = 60 x 12).
Identify and use the appropriate symbol to distinguish between expressions that are equal and expressions that are not equal (e.g., 256 − 13 = 220 + 23; 143 + 17 = 140 + 20; 457 + 100 ≠ 557 +100).
A variable is a symbol that can stand for an unknown number (e.g., 𝑎 + 4 = 6) or for a quantity that changes (e.g., the rule or generalization for the pattern for an input/output table such as 𝑥 + 2 = 𝑦).
Mathematical relationships can be expressed using equations (number sentences).
The equal symbol (=) means that the values on either side are equivalent (balanced).
Identify the equality (=) and inequality (≠) symbols.
Mathematical relationships can be expressed using equations.
