UnboundEdGrade 2 Standards Guide: Operations & Algebraic Thinking

Supporting grades: 2

Description: Explanations and examples of how to implement the Operations & Algebraic Thinking standards in Grade 2. In the following example, students use the associative property of multiplication to show that if 6 is a factor of a number, then 2 and 3 are also factors of that number. Let's use the associative property to see if 2 and 3 are also factors of 42. Let's now move the parentheses to first multiply 3 times 7, to associate 3 with 7 rather than 2. Have students use the associative property to prove that since 6 is a factor of 60, both 2 and 3 are also factors.
