This activity, written to comply with the NCTM Standards, and to support the Texas Essential Knowledge and Skills (TEKS) uses a geometric pattern to teach that important concept of finding patterns and deriving a formula to fit the data.URL http://math.rice.edu/~lanius/Lessons/Patterns/rnotes.html
Grade Levels: 7-12 (Even though finding the formulas might be too hard for lower grades, they can use part of the patterning activities)
Activity Procedures: In this lesson students will:
- Study 3 stages of a geometric pattern,
- Organize their information in a table,
- Look for number patterns,
- Write formulas and graph the relationships,
- Examine growth rates,
- Multiply polynomials, and
- Use formulas to make predictions.
Mathematics Topics: number patterns, relations, functions, formulas, graphing, linear and quadratic equations, constant differencing, symmetry.
Connecting Mathematics: Connects algebra and geometry.
Materials and media: Square grid paper, Internet access or print-out of activity, color tiles (optional)
Suggested Assessment: Questions with answers are provided, along with an explantion for finding the formulas. Evaluating student-created designs and tables provides an excellent form of assessment.
