Scaffolding and Differentiation for ELL Students in Math - HMH

Level differentiation in the N.B. Istomina mathematics curriculum for 3rd grade focuses on adjusting the complexity of tasks to match a student's current cognitive development while maintaining a common educational goal. This approach, central to the "Harmony" educational system, moves away from rote memorization toward developing logical thinking and self-correction. 📘 Core Principles of Istomina’s Differentiation

The curriculum utilizes "multi-layered" assignments where the base mathematical concept remains the same, but the depth of analysis varies.

Requires the student to reverse-engineer the multiplication process. Level 3: Creative (The Challenge) Goal: Logical synthesis and independent discovery. Example: "The area of a rectangle is . If one side is increased by , the new area becomes . Find the original sides." Requirement: Multi-step reasoning and hypothesis testing. 🛠 Classroom Implementation Strategies

In the 3rd grade, focus shifts to multiplication, division, and area. Differentiation typically follows three levels: Level 1: Reproducing (The Foundation) Mastery of basic algorithms and definitions.

Teachers using Istomina's methodology often organize the lesson into specific phases: Differentiated Activity

Applying knowledge to non-standard but familiar situations.

Calculating the area of a rectangle with given sides using the standard formula
