Concept of multiplication as repeated addition, solving multi-step word problems, and perimeter. Multi-Digit Arithmetic & Measurement
Natalia Borisovna Istomina's assessment materials, particularly the for grades 1–4, are foundational components of the "Harmony" educational system in Russian primary education. These works are designed not just to test final knowledge, but to diagnose a student’s mathematical thinking and their ability to apply logic beyond rote memorization. Core Philosophy and Structure istomina kontrolnye raboty 1-4 klass
Istomina's approach emphasizes —the ability to suppress incorrect intuitive answers in favor of logical ones—which research shows is vital for long-term math achievement. By using these control works, educators can move students from concrete experiences to abstract reasoning through a structured, incremental progression. The control works for grades 1–4 are characterized
The complexity of the control works scales as students progress through the primary years: Primary Assessment Focus Key Competencies Tested Number Sense & Basic Operations addition/subtraction within 20
Istomina’s methodology shifts away from traditional drills, focusing instead on . The control works for grades 1–4 are characterized by:
Identification of numbers, addition/subtraction within 20, and recognizing simple geometric shapes. Multiplication & Two-Digit Operations
: They are designed to help teachers identify why a student made a mistake—whether it was a computational error or a misunderstanding of a mathematical relationship.
