Which grade level focuses on addition and subtraction usage on worksheets and timed tests?

The focus on addition and subtraction through worksheets and timed tests is primarily emphasized in the second-grade curriculum. At this stage, students are typically solidifying their understanding of basic arithmetic operations. During second grade, learners not only practice simple addition and subtraction but also begin to develop more efficient strategies for solving these problems, often through repetitive practice that includes timed assessments. This emphasis prepares them for more complex mathematical concepts they will encounter in later grades, such as multi-digit addition and subtraction.

While first-grade number sense does introduce addition and subtraction, it is often in a more foundational context with a focus on understanding the concepts and using manipulatives, rather than on the speed and accuracy required in timed assessments. Third and fourth grades expand on addition and subtraction to include more complex operations and introduce multiplication and division, thereby shifting away from the sole focus on basic addition and subtraction practice.
