One of the most common concerns elementary teachers have: “They’re still mixing up b and d… is it dyslexia?” Letter reversals is NOT dyslexia. This is actually called mirror invariance. The brain is designed to recognize objects as the same no matter the direction. That helps us in everyday life, but reading asks the brain to do the opposite. Now direction suddenly matters. This is why we explicitly teach letter formation.

Writing letters in a consistent way helps anchor orientation, connect sound to symbol, and build a stable reading pathway.
