Math Grade 2 Quiz Represent and solve problems involving addition and subtraction- 2.OA.A.1

The Common Core Standard CCSS.MATH.CONTENT.2.OA.A.1 pertains to the mathematical skill of using addition and subtraction within 100 to solve various word problems. Students are expected to decipher problems that present scenarios of adding, subtracting, joining, separating, and comparing quantities. Furthermore, these word problems can have unknowns (or variables) in any position, meaning the unknown could be the result, or part of the components being added or subtracted. An important aspect of this standard is the representation of problems using drawings or equations, wherein a symbol (often times a letter) is utilized to represent the unknown value.
