KS3 Dyslexia Spelling Intervention – DMFSS Structured Literacy Routine

Support KS3 students with dyslexia to build secure, lasting spelling memory using this neuroscience-informed intervention pack, grounded in orthographic mapping, morphology, and spaced retrieval practice.

D.M.F.S.S is a compact, repeatable five-step spelling routine — Decode–Map, Morph–Build, Fluency–Time, Syntax/Semantics, Space–Revisit — designed to reduce fragile spellings by linking sounds to letters, breaking words into meaningful parts, and revisiting them at structured intervals (D+1, D+3, D+7, D+14). This pack gives teachers and SENCOs everything needed to run a full 10-week programme with KS3 dyslexic learners.

What’s Inside
A 21 page PDF (including cover/back page) containing the following:

• DMFSS Routine Overview – Introduction to all five steps with classroom rationale, grounded in orthographic mapping research.
• Quick Start & Materials Guide – At-a-glance setup guide covering student and teacher materials needed to begin.
• How Spacing Helps Spelling – Accessible teacher-facing explanation of spaced retrieval practice and why the 1–3–7–14 interval pattern is particularly effective for dyslexic learners.
• Gating Rules – A mastery guide ensuring accuracy precedes fluency and unstable words return to Decode–Map before progressing.
• Day One Routine Visual – Colour-coded session overview with time allocations for each step, suitable for display at the front of the classroom.
• Day 1 Student Spelling Sheets (x2) – A3-ready printable worksheets guiding students through all five routine steps, from phoneme segmentation to spaced write-from-memory.
• Student Book Slips – Tear-off weekly tracking slips with spelling list and D+1/D+3/D+7/D+14 check columns for student self-monitoring.
• 10-Week KS3 Spelling Word Lists with Rationale – 10 morphologically grouped lists built around high-frequency Latin and Greek roots (struct, spect, port, dict, photo, graph, tele, -ible/-able, chron, inter), with an explanation of why this approach reduces cognitive overload.
• Morphology Word Cards – Lists 1–10 (60 words) – Illustrated cards for all 60 programme words, each showing the full prefix/base/suffix breakdown and word type.

How to Use
Use as a structured 10-week KS3 intervention in small group or SENCO-led sessions, or draw on individual components to supplement existing spelling provision. Print and laminate the Day 1 sheets for repeated use with whiteboard markers. The Book Slips and spaced retrieval schedule make it straightforward to embed check-ins into tutor time or lesson starters with minimal additional planning.
