How EDI Supports Math

Recently, headlines have shared with us a concerning trend in U.S. education: only 22% of 12th graders are proficient in math, the lowest since 2005. This decline is not just a post-pandemic situation; it’s part of a broader, long-term issue affecting students across various demographics (The Wall Street Journal).

In these challenging classrooms, Explicit Direct Instruction (EDI) emerges as a proven method to address these gaps. EDI creates a classroom environment where every student can actively participate, understand mathematical concepts, and build the confidence needed to succeed.

How Explicit Direct Instruction Supports Math

1. High-Frequency Engagement

• Students respond 2–3 times per minute.
• Supports ELs, SPED, and reluctant learners.
• Keeps every student active and accountable.

2. Concept-Based Lessons

• Focus on understanding why before learning procedures.
• Builds deeper conceptual knowledge that transfers across problems.

3. Think-Aloud Modeling

• Teachers verbalize their thinking.
• Shows students how to approach problems and internalize strategies.
• Supports academic language development.

4. Built-In Vocabulary Support – Integrated across lessons using sentence frames and visual models.

• Tier 1: Basic words like same, less, greater with visual models.
• Tier 2: Academic words like calculate, quantity, equivalent, with explicit definitions, sentence frames, and repeated use.
• Tier 3: Domain-specific math terms like percent, decimal, hundredths, with visual supports and multiple examples

5. Strong Sentence Frame Support – Sentence Stems and/or Sentence Starters

• “Which figure below shows a unit fraction? ___ shows a Unit Fraction Because…”
• “___ would be greater than the original quantity because…”

6. Check for Understanding.

• Quick checks every 2–3 minutes.
• Allows teachers to identify who needs reteaching.
• Minimizes learning gaps in real time.

7. Coaching & Feedback

• Onsite or virtual coaching cycles.
• No one improves in isolation.
• Lesson modeling, co-teaching, and feedback.
• Supports teachers in applying EDI practices with fidelity.

Conclusion:

EDI ensures that every math learner is engaged, supported, and successful. By combining high-frequency engagement, concept-based lessons, modeling, vocabulary scaffolds, sentence frames, and immediate feedback, teachers can create classrooms where every student responds, reasons, and grows mathematically.
