It is a hot sunny Saturday morning on the farm. Maya, Duksie and Doobie are helping Mama K in her vegetable garden. The children work all morning.
Mama K always gives the children a treat for helping her. Sometimes it's cake or chocolate; sometimes it's apples, pears or oranges. Mama K has only one rule. "Share it fair!" The children know they must share the treats equally, so they all get the same amount.
Today Mama K has baked a round strawberry cake with pink icing (糖霜) and berries from her garden. The children wait on the grass for their treat. "Here you go!" smiles Mama K. "But remember the rule. Share it fair!"
Maya has the first turn to share the cake. She uses the knife to draw lines in the icing. The others watch her. She does not cut the cake yet. The others must first agree if her way is fair. "I think I will make two cuts down like this. Now we have three slices, all the same!" Maya shows them. There is one line on the left and the other on the right.
"No way!" says Duksie. "The one in the middle is much too big!" Doobie also shakes his head. Maya laughs and tells Duksie to try.
"Pass me the knife.I'll do it," says Duksie First she rubs out Maya's pattern in the icing, and then she makes one cut across and one down. "Look, I have made my three slices!" "That's not fair!" shout Maya and Doobie together,.
"Why don't you try, Doobie?" says Duksie. "I bet you can't do it!"
"I wish the cake was a square, and then it would be easy!" says Doobie thoughtfully. And then! A picture comes into Doobie's head. He sees the silver badge (标识) at the front of his father's big red Benz truck. "I've got it! I've got it! I know how to do it," shouts Doobie.
"How did you work it out?" Maya asks. Doobie smiles to himself. For now it's his secret. Later, he will tell his dad.
