Suzanne's Mathematics Lessons

# Algebra

aligned to the NCTM Standards - Algebra: Grades 6-8
Algebraic Factoring
Students use algebra tiles to explore algebraic factoring.

Algebraic Thinking
Lesson plan for the "Fruit for Thought" activity which is a variation of "The Variable Dilemma."

Building A Pyramid (English version) || Construyendo Una Pirámide (Spanish version)
In this activity from Frisbie Middle School's Multicultural Math Fair students work on a hands-on exercise: from net to geometric solid. The Bonus requires students to use algebraic equations.

Dominoes
A classroom activity (similar to Pentomino + 1 = Hexomino; a variation on polyominoes) to be explored through manipulatives (paper dominoes). Students explore whether it is possible to cover a 6x5 grid with 15 dominoes, then build a variety of "brick walls" and create a brick wall catalogue. A simple freeware program (Macintosh only) by Kurt Kaufman can be used very easily to model this problem. Links to related pentomino and Fibonacci sites on the Web.

Graphing Linear Equations
A Palm OS handheld activity to use with students to have them create, investigate, and learn about graphs of linear equations.

Graphs to Go
In this activity from Frisbie Middle School's Multicultural Math Fair students work a sports-related statistics problem.

Graphing Exponential Functions
Step-by-step directions to create graphs of exponential functions using a Claris Works spreadsheet file.

Graphing Linear Functions
Step-by-step directions to create graphs of linear functions using a Claris Works spreadsheet file.

Graphing Polynomial Functions
Step-by-step directions to create graphs of polynomial functions using a Claris Works spreadsheet file.

Lewis Howard Latimer
In this activity from Frisbie Middle School's Multicultural Math Fair students work through a mathematical investigation using the work of Lewis Howard Latimer.

Leonardo da Vinci
Question: Is the ratio of our arm span to our height really equal to 1? If an emphasis is given to a/h = 1, this can be an engaging activity using variables.

Locker Problem
A classroom activity (also called 1000 Lockers) to be explored through the use of manipulatives and a ClarisWorks spreadsheet. Students then look for patterns and write the answer algebraically.

A variety of of resources on the Web emphasizing algebraic thought while still addressing each of the particular Standards for grades 6, 7 and 8.

Operations with Integers
Lesson plan and tutorial for the Macintosh shareware program, Math Stars, by Roger Clary. Includes ideas for introducing integers even if the software is not used.

Tower of Hanoi (English version) || La torre de Hanoi (Spanish version)
In this activity from Frisbie Middle School's Multicultural Math Fair students interact with an age-old exercise in finding a mathematical pattern.

Traffic Jam
A classroom activity (also called Hop, Skip, Jump) to be explored through large movement experience, manipulatives, and an interactive Java applet. Students then revisit the activity, look for patterns, and write the answer algebraically.

The Variable Dilemma
Students are given the following prompt: Each letter in the equations below stands for a different number (0 through 9). Find the values of each letter (A through J). Here is a link to the rubric used to grade this assessment.
