Dn's teacher has given him one of these rulers saying he found it easier to read using the yellow section. Nephew confirms this but ds didn't get a chance to ask what, if anything, this indicates.
Obviously her first thought was dyslexia but can other issues be indicated?
He's a lovely,bright, well mannered boy(8) but has been falling behind in reading, writing and maths recently.
Anybody know anything about this aid?
