FEATURES
Laying Siege to Parabolic Understanding
John W. Rick
An attack on a domino castle using a trebuchet is one way to help students storm a wall of understanding while learning about medieval mathematics.
Second Look: Quadratics
Online Extra: Activity Sheets
Proof: Examples and Beyond - FREE Preview!
Eric J. Knuth, Jeffrey M. Choppin, and Kristen N. Bieda
Asking
middle school students to verify the math they do requires them to think about proof. By doing so, students construct arguments in the
middle school and are more ready for proof in high school.
Algebraic Reasoning through Patterns
F. D. Rivera and Joanne Rossi Becker
Findings, insights, and issues drawn from a three-year study on patterns are intended to help teach algebra.
Bursting with Geometry
Beth Cipoletti and Nancy Wilson
By building a Lithuanian sunburst star, students can explore a number of geometric relationships and enforce their mathematical vocabulary.
The Power of Incorrect Answers
Brittany L. Hoffman, M. Lynn Breyfogle, and Jason A. Dressler
To bolster students’ ability to prove as well as develop
mathematical argumentation skills, create an environment in which students must regularly explain and justify their thinking.

Second Look – Quadratics
A Rhythmic Approach to Geometry
March 2002, Volume 7, Issue 7, Page 378 - MTMS
Students can form beautiful curves through a kinesthetic experience by using a dynamical geometry program. The examples included are parabolas, pursuit curves, spirals, and more.
Mathematical Explorations: Batty Functions: Exploring Quadratic Functions through Children's Literature
August 2007, Volume 13, Issue 1, Page 52 - MTMS
The information in two children’s books is analyzed and graphed. Worksheets are included.
Using Models to Build an Understanding of Functions
January 2001, Volume 6, Issue 5, Page 310 - MTMS
How to plan and organize instruction to help students understand the function concept and to make the mathematics explicit. Linear, quadratic, and exponential functions are explored through use of manipulatives and data collection.
Patterns and Functions
Illuminations Lesson: Students investigate properties of perimeter, area, and volume related to various geometric two- and three-dimensions shapes. In so doing, they discover the salient features of the pattern, construct understandings of concepts and relationships, develop a language to talk about the pattern, integrate, and discriminate between the pattern and other patterns. When relationships between quantities in a pattern are studied, knowledge about important mathematical relationships and functions emerges.
