Number Talks

Number Talks, often called math talks, are a brief daily classroom routine where students mentally solve computation problems and talk about their strategies. Students learn to make sense of mathematics in their owns ways, learn to critique the reasoning of others, and make convincing arguments about the math.

Variable Analysis - Students analyze a set of numbers to determine a pattern (or function). This website has many examples in its archive.
