8. How? Why Number Talks in Elementary Classes?
There are lots of ways to do Number Talks and lots of purposes. We based what we do on the Sherry Parrish book.
It isn’t hard to have kids do math with a group but this must be purposeful!!

9. Teach students hand signals
“Simply defined, number talks are five- to fifteen-minute classroom conversations around purposefully crafted computation problems that are solved mentally.”
Sherry Parrish, Teaching Children Mathematics October 2011
Teach students hand signals
Choose a strategy and present a string of problems
Accept all answers
Have students justify their answers
Make a written record
Can’t emphasize enough the purpose part
