Pay $0.24 for each banana OR Pay $1.99 per pound of bananas?
Whichever option you choose, justify your decision with mathematics.

Love it but I wonder how much real-world knowledge of the size of a bunch of bananas comes into play here.
Good point. Would it help if I had another bunch on a scale for comparison?
S’s “I want one banana because I won’t eat the others and they will go to waste.” “I need to know how many bananas are in a pound.” “I would buy the pound of bananas because buying one normally costs more.” Wow thanks for making my students think.
You’re welcome! Did you throw in the twist of “you can break off a banana to make it a bunch that you would actually eat before they go bad”? That’s a funny twist that I didn’t expect.
Happy Birthday! says Ramiro.
Lorraine pointed out that it’s about 6 bananas to a pound, so it’s worth it to buy them individually.
Jesus noted that two bananas for $0.48 is a better deal than two bananas for $1.99 (which is a pound).
Armando pointed out that it’s better to get the cheap ones because you could get about 8 if you buy them individually.
I presented the problem to my students “as is” so that THEY could come up with the additional information they would need. They realized they needed to know how much a banana weighs, and how many bananas are in a pound. Today we will be weighing an assortment of bananas and averaging their weights so that they can make their determination. I like having open questions where NOT all the information is included. That’s real world problem solving!
This is incredible. Please share about the conversations that happen after!
