Reading Ruller — reading & writing aid

The Reading Ruler is a small tinted see-through strip (blue or yellow) that slides under each line of text. Its colored window frames one sentence at a time and calms the swirl of words that seem to "jump" off the page. A simple, dependable tool from our Reading and Writing line, priced at just $1.99.

Why we love it

The colored overlay reduces the glare of white paper and boosts contrast, which helps dyslexic and ADHD children who lose their place. By guiding the eye, the ruler makes reading less tiring and rebuilds confidence.

• Tracks the line so kids skip fewer words and re-reads
• Tinted window that eases visual fatigue
• Lightweight enough to tuck into any book or pencil case
• Great at home, in the classroom and in tutoring

How to use it

Place the ruler under the line being read and slide it down at the child's pace. Made of soft, safe plastic, it wipes clean in seconds. Recommended from age 5, it supports early reading and elementary homework alike.
