### Assorted math conversations

A collection of little items from the last month.

# Optimal time to eat

P was talking with the kids about what order they should eat their food, which led to lots of graphs showing flavor over time. I don't know if this is a typical conversation for other people, but pretty common in our house. Here are some of the charts they made: Naturally, this also led to other charts. In particular, a debate about how quickly someone could develop skills by practicing music. Note the lack of labeling on the y-axis.

# Some challenges

At lunch today, everyone got a math question. Apologies, I don't remember what challenge we gave to J1. J3 was given what is 5 + 2? After we let her consider and answer, J2 got asked what is the cube root of 125? Before either older kid could answer, J3 yelled out: 5.
Hmm. No, we also don't think she really understood, but it is nice to dream!

# A joke

J2: look, a prime! (pointing generally at the 100 chart on our wall)
Everyone look expectantly at the wall
J2: No, it isn't. 22 is a compositive
All little Js burst into hysterical laughter. P looks at me as if to say, "this is your fault."

# I wonder

From nowhere: Daddy, what 3 digit number has the most factors?
