Math and Multimedia Carnival Criteria for Selection of Articles

The Mathematics and Multimedia Blog Carnival is now accepting articles  for the next issue. Although any math article might be accepted, below are the Revised Criteria for Blog Carnival Selection.  This will be characteristics of the articles that will be prioritized.  Articles with no links are done, but not yet posted.

1. Connection between and among different mathematical concepts

2. Connections between math and real life; use of real-life contexts to explain mathematical concepts

3. Clear and intuitive explanation of topics not discussed intextbooks, hard to understand, or  difficult to teach

4. Proofs of mathematical theorems in which the difficulty of the explanation is accessible to high school students

5. Intuitive explanation of higher math topics, in which the difficulty is accessible to high school students

6. Software introduction, review or tutorials

  1. Investigating Polyhedrons with Poly
  2. GeoGebra Tutorial Series

7. Integration of technology (Web 2.0, Teaching 2.0, Classroom 2.0), in teaching mathematics

  1. Using Google Sketchup in Teaching Mathematics
  2. Use of Google Docs  in Teaching Mathematics.

Mathematics and Multimedia Blog Carnival is still in its infancy, so please help spread the word about it. I would appreciate if bloggers who has benefitted from Mathematics and Multimedia, especially those whose article was accepted in the previous carnival, would announce it in their blogs.

To submit article the Math and Multimedia Blog Carnival, click  here.

The Math Teachers at Play Carnival and Carnival of Mathematics are also accepting math articles for their carnivals. Please do not duplicate submissions.

Erlina Ronda of Keeping Mathematics Simple will host the Mathematics and Multimedia blog carnival special edition on December 2010.  Her topic will be on Teaching Algebra Concepts. You can email her to submit in advance.

Enhancing your Geometric Drawings with Google Sketchup

If you would like to enhance your geometric drawings, then Google Sketchup is one software that I would recommend. Google Sketchup is 3-dimensional modeling software designed for architects, engineers, filmmakers and game developers, and other related professionals (Wikipedia).  It is now used to create models in Google Earth.

What makes Google Sketchup advantageous over other 3d software is that  it is a lot easier to use.  Some of the examples below are the figures I created after only watching several of their video tutorials.

Figure 1 shows the model in perspective showing symmetries of a right rectangular prism.

Figure 1 - Symmetries of a right rectangular prism.

Figure 2 shows the painted cube problem my Introduction to the Concept of Functions post. In the diagram, a big cube is painted yellow and cut into smaller cubes. The problem is to investigate the number of painted faces.

Figure 3 shows different face styles of a cuboctahedron.

Google Sketchup is free, and you can pay if you want a professional version. There are basic, intermediate and advanced video tutorials in its website.
