Xander and
XuMei and their two friends made a cake. They did it without a recipe. They thought about what they know about food and cake and baking and they added ingredients. There was discussion and disagreement about what should go into the cake so some smaller cakes were made to allow for different combinations of ingredients.

Where to put the toppings? And which tasty treats on what sections of the cake?

What should the frosting be?
Xander took his cakes off the top to avoid the dairy.
Everything is better with sprinkles.

The cake was delicious, very sweet and filled with fun. Very little of it was actually eaten, though. The joy was in the making.

I was reminded of this cake baking day when I came across a page on Sandra
Dodd's site called:
Cake as Sacrificefascinating stuff, cake....:)
Since this cake we have baked several other cakes.
Lemon Cake, and
Vegan Chocolate Cake most recently. The Vegan Cake was awesome and led to
discussions about chemical reactions so now I am researching the best
Chemistry set and finding more science experiments we can do at home. Xander is watching
Robert Kampf --The Happy Scientist,
BrainPop and various You-tube videos on chemistry and other science related topics.
XuMei is exploring commerce and economy. She made hundreds of bills and priced everything in our house. It is a store and a bank. She also created debit and credit cards. They have both become interested in very large numbers.
"Infinity is a concept Mom, not a number. What is the largest actual number."--Xander
So off I go to Google
largest numbers and we are learning about googol, googolplex, Graham's number, large number notation, exponentiation, tetration.
All that and a little cake!
