Number Concept Syllabus
1. PROGRAM TITLE: InterMath  Number Concept
2. GOALS ADDRESSED
Participants will:
 Expand and strengthen their mathematical knowledge and capabilities, specifically in the domain of number concepts by investigating challenging problems
 Engage in problem solving by identifying patterns, forming conjectures, and developing proofs through the use of technology
 Use mathematicsspecific technologies such as dynamic geometry software, graphing programs, spreadsheets, and the Internet to explore number concept investigations
 Write and post online solution processes to the investigations using web page development software
 Develop middle school mathematics instructional activities and strategies that incorporate technologyenhanced mathematical investigations
 Develop a network of peer educators available for continued support during and following the workshop
3. IMPROVEMENT PRACTICES
Participants will gain knowledge and practice in developing instructional activities and strategies for teaching number concepts in the middle school classroom in order to positively affect student achievement. Participants will also improve their own mathematical competencies in the area of arithmetic.
4. COMPETENCIES
Participants will be able to:
 Select and use appropriate technological software to explore, analyze, and represent arithmetic problems
 Communicate their mathematical thinking by expressing their reasoning, analysis, and extensions of the mathematical concepts associated with an investigation in written, verbal, and visual forms
 Modify arithmetic investigations for appropriate use in the middle school classroom
 Make connections between InterMath experiences and standardsbased reform documents, such as the NCTM standards
5. PERFORMANCE INDICATORS
As a result of this course, participants will demonstrate their ability to:
 Incorporate technology into the learning and teaching of number concepts
 Communicate mathematical understanding of a variety of number concepts in the form of an online portfolio of investigation solutions
 Plan middle school instructional activities based on InterMath experiences
6. PREPARATION PHASE
Dates: Fall 2002
Instructor: Dr. Wilson/Dr. Gootman
Location: UGA campus
Strategies: Internet exploration, electronic and classroom discussions, lectures, exploration of mathematical investigations, investigation writeups, collaborative brainstorming, lesson planning, presentations
7. ASSESSMENT
Participants will be assessed on the content and quality of their online portfolios. Feedback and suggested modifications for a select number of writeups will be provided throughout the workshop. Assessment will be based on use of representation, analysis, appropriate selection and use of technological tools, creation of extensions, and accuracy of mathematics. In addition to the investigation writeups, the participants will also create a mathematics lesson that integrates technology and number concepts for use in their own classroom. An endofcourse exam will be given to assess students on their mastery of mathematical abilities in the area of number concepts.
