Please help with name of game

[av1d@aol.com.net (av1d)]

I apologize if this is asked too often.
When my sister and I were about 6 years old, we visited the library every
weekend to use the Apple IIe and get books.
There was an educational game that we would play often, but I cannot remember
the title, hopefully you do!
The beginning may have had a screen where you would type in a word, or possibly
it was a menu to select which game you'd like to play.
One of the games had a bath tub. You were presented with a mathematical problem
(addition and subtraction), and if the answer was wrong, the tub would fill up,
eventually overflowing.
There was a seperate game (part of the same title) that used fractions.
It measured ingredients, and if you were wrong with the math problem, a cake
would explode or something (memory is sketchy, it was a long time ago! :).
This is all I remember about the game, unfortunately.
If it's any help, it's similar to the game "ChemLab", if anyone remembers that
aswell.
Thanks for your help.
