FEATURES

The A-Maizing Corn Lab: A Geneticist's Biography Leads a Mathematics Exploration
Julie Cwikla, Marcelle Patterson
An innovative lesson that integrates genetics, literature, and mathematics as a context for students to investigate patterns on Indian corn. This two-day lesson requires students to estimate, collect data, identify and describe patterns, represent their data using bar graphs, use Punnett squares, and investigate probability. Includes questions to be used for worksheets, and samples of student work.

Developing Algebraic Thinking through Pattern Exploration
Lesley Lee, Viktor Freiman
How to scaffold classroom questioning —using the growing T pattern—to bring out the best in students' algebraic thinking. Includes sample questions, as well as examples of students' solutions.

Why, Why Should I Justify?
John Lannin, David Barker, Brian Townsend
Various justifications underlying students' algebraic generalizations. Includes sample questions for student exploration, as well as possible student responses.
