Hello,
For your logo I decided to create a fun and modern graphic of a 1950's style teacher standing by the blackboard/logo with a chalk in her hand.
The font for "classroom" is a font with a retro feel, while the rest are more modern, to distinguish the logo with its own personality. The "o" in classroom is part of the icon/branding provided.
This has a fun feel, while still maintaining the branding of your company.
Any revisions welcome.
