Why students forget — and what fixes it

Re-teaching isn't the problem. The pattern never got mapped.

Your student spells "reason" on Friday and writes "reson" again Monday. That's not laziness — it's orthographic mapping that never finished. Every Orthos resource starts with one question: what is the student actually struggling with?

1

Diagnose the pattern

Start with data, not guesswork. Pinpoint exactly which syllable type or pattern is breaking down — closed, open, VCe, vowel teams, r-controlled — so you target the gap instead of reteaching everything.

2

Teach it explicitly

Scripted lessons, editable slides, decodable practice, and high-engagement games — built on explicit instruction, immediate feedback, and consistent chances to apply the skill.

3

Monitor & map it

Progress-monitoring tools that inform instruction and show the growth — so the pattern moves into long-term memory and you can prove it on the IEP.

Who's behind Orthos

Hi, I'm Keegan — a special-ed teacher building Orthos from inside the classroom.

As a special education teacher working with students who have documented reading and spelling disabilities, I've spent countless hours analyzing errors, finding the pattern, and designing instruction that targets the root cause — not just the symptom.

Every lesson, game, and assessment in the store has been used with real students, refined through classroom experience, and redesigned when it didn't produce results. Orthos is everything I build along the way — and the videos where I teach it out loud.
