The curriculum focuses on several core areas that form the basis of the 13 yearly control tests:
: One major error or 1–2 minor mistakes (such as a calculation slip), provided the logic of the word problem is correct. The curriculum focuses on several core areas that
: Introducing equal groups, arrays, and the basic concept of sharing/multiplying. Kozlova, T
: Mastering mental and written strategies for calculations within 100, including carrying and borrowing. Key Topics for Control Works
: Multi-step word problems that require extracting information and selecting the correct arithmetic operations. Example Control Work Structure
: Direct calculation of expressions, often including brackets to check the order of operations.
In the 2nd-grade mathematics program by S.A. Kozlova, T.E. Demidova, and A.P. Tonkih (part of the "School 2100" educational system ), control works are designed to assess both standard computational skills and the ability to apply mathematical logic in complex situations.
