We introduce the Into Math Graph tool, which students use to graph how “into" mathematics they are over time. Using this tool can help teachers foster conversations with students and design experiences that focus on engagement from the student’s perspective.

Connecting Research to Teaching: Evaluating and Writing Dynamic Geometry Tasks
Aaron Trocki
The advent of dynamic geometry software has changed the way students draw, construct, and measure by using virtual tools instead of or along with physical tools. Use of technology in general and of dynamic geometry in particular has gained traction in mathematics education, as evidenced in the Common Core State Standards for Mathematics (CCSSI 2010).
Media Clips: Mosquitoes; Pythagorean Baseball
John Donovan, Gregory D. Foley, and Thomas R. Butts
Students analyze items from the media to answer mathematical questions related to the article. This month's clips examine why raindrops do not crush mosquitoes and feature an application of the Pythagorean theorem to baseball. The mathematics involved includes dimensional analysis, ratio and proportion, and the Pythagorean theorem.
