Orton-Gillingham (OG) is a structured, sequential approach to literacy developed in the 1930s by neurologist Samuel Orton and educator Anna Gillingham. It was originally designed for students with dyslexia and decades of research have shown it to be one of the most effective approaches for any struggling reader.
OG is not a programme. It is a set of principles: teach explicitly, teach sequentially, teach to mastery, and always engage more than one sense at a time. Every TerraLit lesson is built on these principles from the warmup through to the final spelling word.
All materials generated by TerraLit are based on the OG scope and sequence. We know every learner is different. These tools are designed to save you time in lesson preparation and resource creation. They are a starting point, not a substitute for your professional judgement. The best lessons still happen when a skilled teacher reads the room, adjusts the pace, and responds to the learner in front of them. TerraLit gives you the structure. You bring the teaching.

"Loved the customisable features. Used it fully on screen with my child — it felt natural and structured."
"The lesson structure is thorough. Covers everything I need in one place — I can see this saving me hours every week."
TerraLit has three generators — Phonics, Spelling Rules, and Syllabication. Each follows the same simple flow: pick your options, generate, deliver or print. Here's how to use each one.
"This makes it so much easier for me especially with a newborn. I have been too tired lately and this helps me decide if I want to do things sequentially or targeted without having to piece together physical materials.
I love the customisable feature of TerraLit. The programme is almost like an open-and-go book. The fact that it is digital saves me time flipping through a physical book and makes learning accessible on the go or when we choose to have lessons outdoors.
I also like the kinaesthetic approach because it helps my child get into the learning mode. Thank you for making the programme clear and concise. It has made lesson planning so much less stressful such that I look forward to teaching the next lesson."
"The lesson structure is thorough and covers everything I need in one place. I can see this saving me hours every week. The fact that it follows the OG sequence means I do not have to second-guess whether I am teaching in the right order. It just flows."
"I was not familiar with OG before I tried TerraLit. I expected it to be complicated but the generator walks you through the structure clearly. I used it with a student who has been struggling with spelling for two years and within the first session I could already see why the approach works. It is explicit, it is sequential, and it makes the student do the thinking. I will be using this regularly."
"Simple and practical. I tried it once and immediately understood how to use it. My son actually enjoyed the warmup which is saying a lot because he usually resists anything that feels like school."
