Name is obviously about nurturing and growth. Building foundations. Connecting ideas, developing and expanding skills.
The basic thought is a stylized greenhouse with the text "math greenhouse", but you are free to be creative and innovative.
The name is a mouthful, so maybe there's a clever way to make it look smaller.
Avoid childen's primary colors and the "kids" look. Absolutely no bubbly, or crayon/chalk fonts or backwards r's.
This is targeting the parents, not the kids. This is premium. Don't look cheap. Favor elegant precision, but don't be too cold. Avoid cartoons and childishness.
Not too tall, say 55 px-ish. bonus love for favicon.
UPDATE: 1) Greenhouse is one word. If you like, you can split it across two rows,but whether one line or two, it must be in a consistent typeface & color. It's NOT just a house that is green, it's a greenhouse.
2) You can put a leaf on the roof, but not a chimney. Greenhouses don't have chimneys. Especially not polluting ones.
