Does your project involve redesigning a kitchen space in your home? How would you plan for storage? For food preparation?

 

Munir is making a batch of cookies. He is using a favourite recipe from his grandmother’s cookbook. The recipe calls for two ounces of fresh butter. He asks his sister for advice. Listen in.

 

 

“How much butter is two ounces?” asked Munir.

 

 

“I think ounces are parts of a pound,” his sister answered.

 

 

 

“Well,” Munir complained,” I just bought this brick of butter and all it says on the wrapping is 454 g. Now what?”

 

How would you help Munir add the correct amount of butter?
