Standards for Mathematical Practice
Use appropriate tools strategically.
Mathematically proficient students consider the available tools when solving a mathematical problem. These tools might include pencil and paper, concrete models, a ruler, a protractor, a calculator, a spreadsheet, a computer algebra system, a statistical package, or dynamic geometry software. Proficient students are sufficiently familiar with tools appropriate for their grade or course to make sound decisions about when each of these tools might be helpful, recognizing both the insight to be gained and their limitations. When making mathematical models, they know that technology can enable them to visualize the results of varying assumptions, explore consequences, and compare predictions with data. They are able to use technological tools to explore and deepen their understanding of concepts. 

The educational non-profit organization GeoGebra provides free dynamic mathematical software in an effort to improve global mathematics education. GeoGebra develops the open-source software GeoGebra for students and teachers all over the world. 

The GeoGebra Institute of Iowa is a part of an international network of teachers and researchers from all over the world known as the International GeoGebra Institute (IGI), working together to promote the learning and teaching of mathematics.

This web site will be developed to support the GeoGebra Institute of Iowa's mission of promoting and supporting collaborative efforts of mathematics teachers in Iowa interested in using GeoGebra in their classrooms while linking them to the international GeoGebra community.

The  primary goals for the GeoGebra Institute of Iowa are:
  • to promote the use of a broad range of applications of GeoGebra in elementary, middle, and secondary classrooms that are based on active learning, inquiry, creative problem solving, and a commitment to teaching for understanding; and
  • to facilitate collaboration and sharing of resources, designs, and research, including classroom action research.

Anticipated activities for the proposed GeoGebra Institute of Iowa include:

  • Learning about GeoGebra –Sponsor or present workshops for elementary, middle, secondary, and postsecondary mathematics teachers introducing the basics of using the GeoGebra software.
  • Learning to Teach and Learn with GeoGebra – Sponsor or present workshops focusing on pedagogy -- linking GeoGebra with sound pedagogical methods strategies for elementary, middle, secondary, and postsecondary mathematics teachers.
  • Establishing and maintaining a web site that includes online access to both mathematics expertise and technical assistance with GeoGebra.
  • The development of creative ways to involve elementary, middle, and secondary students in extracurricular activities related to GeoGebra, for example, mathematics contests in which teams of secondary students compete in modeling and problem solving challenges.
