Identifying an educational pc game...

I'm looking for a certain game I used to play when I was a kid.
It was probably a 1st or 2nd grade game, and the first thing you do in the game is customize your treehouse with different paintjobs and decorations.
After that, there are various activities to learn from.
There was a science lab where you could learn about coloring carnations,
there was a game where you learn to count money,
and I honestly have no idea what other games were in there,
I just remember that the game was really fun when I was younger.

I hope somebody knows what game I'm talking about!
