My goal for a discussion is to make the “Big Mathematical Ideas” visible by having students construct connections between different solution strategies or attempts.
This blog continues the exploration into mathematical conversations started by Chrissi's earlier blog "Reflecting to Improve Teaching". Come and join my classroom where a group of students has just started to look at the series 1 + 1/2 + 1/4 + 1/8 + … =?
