**Driscoll, M. & Moyer, J. (January 2001). Using Students' Work as a Lens on Algebraic Thinking****,***Mathematics Teaching in the Middle School*, 6(5), 282-287.

This article focuses on the use of student work to help teachers focus on teaching and learning algebra.**Kalchman, M.S. (August 2005). Walking through Space: A New Approach for Teaching Functions in***Mathematics Teaching in the Middle School*, 11(1), 12-17.

Kalchman shares a real-life scenario for introducing several key aspects of linear functions.**Kriegler, S. Just What is Algebraic Thinking?**Submitted for*Algebraic Concepts in the Middle School.*http://www.math.ucla.edu/~kriegler/pub/algebrat.html.

Kriegler discusses three lenses for looking at algebra: algebra as abstract arithmetic, algebra as language, and algebra as a tool for the study of functions and mathematical modeling.**Mooney, E.S. (March 2007). The Thinking of Students: Cookies***, Mathematics Teaching in the Middle School*, 12(7), 374-377.

This brief article gives you insight into students' mathematical thinking about this problem: Tim ate 100 cookies in 5 days. Each day he ate 6 more than the day before. How many cookies did he eat on the first day?**Mooney,**Edward**E.S. (December 2006). The Thinking of Students: Elizabeth's Long Walk**in:*, Mathematics Teaching in the Middle School*, 12**(5**(December 2006): 263**), 63-265.**

This brief article gives you insight into students' mathematical thinking about this problem: Elizabeth visits her friend Andrew and then returns home by the same route. She always walks 2 km/h when going uphill, 6 km/h when going downhill, and 3 km/h when on level ground. If her total walking time is 6 hours, then what is the total distance she walks?**Peterson,**Blake**B.E. (November 2006). Counting Dots and Measuring Area: Rich Problems from Japan**in:*, Mathematics Teaching in the Middle School*, 12**(4**(November 2006**)**:**, 214-219.**

Students look at a set of dots and create a variety of generalizable patterns.**Smith,**Margaret**M.S.,**Amy**Hillen, A.F.**Hillen, and Christy L. Catania.**& Catania, C.L. (August 2007). Using Pattern Tasks to Develop Mathematical Understandings and Set Classroom**Norms in**Norms**:*, Mathematics Teaching in the Middle School*, 13**(1**(August 2007**)**:**, 38-44.**

This article discusses the use of pattern blocks to help students develop algebraic reasoning and to establish classroom norms and practices.**Thomas,**David A**D.**and Rex**A. & Thomas, R.A. (October 1999). Discovery Algebra: Graphing Linear Equations in**:*The Mathematics Teacher*, 92**(7**(October 1999**)**:**, 569-572.**http://my.nctm.org/eresources/article_summary.asp?from=B&uri=MT1999-10-569a.

In this article, Thomas shares his personal classroom experience moving toward a new approach to teaching algebra.
