Featured 5-22-2014: The Math Open Reference Project

 

The Math Open Reference Project is free, interactive math textbook on the web covering high-school geometry.

 

 

The Math Open Reference Project has the goal of providing high-quality digital content free of charge to the end user, while providing numerous benefits over paper textbooks:

• Accessible anywhere, any time.
• Interactive, interesting experience.
• Hyperlinks promote exploration and easy lookup.
• Use the search to look up a word or term.
• Interactive quizzes with instant feedback.
• Lower cost.
• Less weight.

Using interactive tools and compelling animations, The Math Open Reference Project provides an engaging way to learn and explore the subject. A vast library of virtual manipulatives can be used to demonstrate concepts using a computer, projector, and whiteboard. Students can use the same manipulatives themselves outside the classroom.

 

 

The Math Open Reference Project meets the NCTM standards for content and is aligned with the Common Core standards, but also has the potential to adapt to and comply with the standards for every state.

 

The Math Open Reference Project will work with most popular browsers, including Internet Explorer, Firefox, Chrome, and Safari. The interactive illustrations use Java and/or Flash, so these plug-ins must be installed on the user's computer.

 

The copyright and license agreement permit any printing for non-commercial use, useful for class handouts.

COD - 1/12/2012 - Sketchpad Explorer [Math]

Drag, manipulate, and animate visual mathematics to develop and generalize understanding of fundamental mathematics concepts across elementary math, geometry, algebra, trigonometry, calculus, and beyond with the free Sketchpad Explorer app for the iPad.

Based on the popular The Geometer’s Sketchpad® software, the Sketchpad Explorer app allows you to interact with and investigate any document created in Sketchpad using a simple, powerful multitouch interface.

Sketchpad Explorer includes activities and workbooks for elementary mathematics , early algebra, and geometry. Users of The Geometer’s Sketchpad can also create and share documents with and for their iPad using iTunes File Sharing.

There are many Sketchpad documents available on theSketch Exchange community site and across the web offering activities, investigations, and interactive visualizations covering a comprehensive range of mathematics topics for learners from K through college.

Catch of the Day - NRICH Mathematics- 5/2/2011

NRICH is a group of teachers specializing in the use of RICH mathematical thinking. The NRICH project offers advice and support to both teachers and learners (ages 5-19) of mathematics.

The NRICH website contains a wealth of rich tasks and guidance. NRICH wants teachers to have a thorough understanding of what is meant by "rich tasks" and what that suggests about classroom practice.

NRICH provides mathematics teachers:

• Free enrichment material that can help inspire and engage learners and embed RICH tasks into everyday practice.
• On-line and face-to-face support at both Primary and Secondary levels to promote RICH thinking in classrooms.
• Professional development courses and workshops in rich mathematics.
• Help in thinking strategically about "next steps" and progression in problem solving.

There are free, interesting mathematical games, problems, and articles for mathematics learners. Students are encouraged to share their solutions to NRICH mathematical problems in a safe online space where they can meet others with similar interests.

Some of the resources available free on the NRICH website are curriculum mapping documents; articles, news, and research/journal items; professional development; and games.

Catch of the Day - MathTV - 8/11/2010

 

MathTV offers free tutorial videos covering topics in basic math, algebra, geometry, trig, and calculus.

Solutions to each example exercise are demonstrated in two or more short videos by different instructors. In each video, the instructor explains and demonstrates the procedure used to solve the problem. Many  of the exercises include solutions demonstrated by Spanish-speaking teachers.

MathTV is also piloting a series of online eTextbooks. Presently there are texts for Introductory Mathematics, Introductory Algebra, and Intermediate Algebra.

In the MathTV Bookstore, textbooks used in one-semester college courses in mathematics are available for purchase. Most of the examples in each of these books are presented in MathTV videos.
