Mr Blue was my math teacher over 20 years ago, I am pleased to see that he still teaches! An exceptional teacher in all aspects - who was fair and considerate to all in his classroom, supporting everyone to challenge themselves (whatever their starting point, with the subject matter). It is teachers like Mr Blue who have a (positive) influence that stays with you throughout your life. I remain grateful for those teachers, like Mr Blue, who provided such value.
If by Blue this means Jim he is one of the best math teachers I've had. Really easy to understand and doesn't over complicate things. Can work out things in his head real fast.
