The Binary Base-2 & Hindu Arabic Base-10 Counting website is an animation of binary (base-2) counting. The animation includes a display of the Arabic (base-10) number to match the binary number.
Type of Material:
This site could be used as a visual illustration for the binary counting system and its relationship to the Arabic counting system by teachers of elementary and middle school students.
Macromedia Flash 5 is required to run the animation. This site was reviewed using both Netscape and Internet Explorer browsers on a PC.
Identify Major Learning Goals:
The learning goal for this site is to develop an understanding of the binary counting system and compare it to the base-10 place-value system.
Target Student Population:
The target students include elementary, middle, and high school level students. This animation site could also be used with higher education students.
Prerequisite Knowledge or Skills:
A basic understanding of the Place-value system. Technology: need to be familiar with the Internet, interactive tools, and Macromedia Flash.
Evaluation and Observation
The animation on this website provides a good illustration for students to visualize the binary counting system. The option to hear the counting of the balls in the animation gives additional assistance to students. The place holders for the counters are presented in organized groups. Sound method for determining the number in base-2.
In addition to using the binary counting animation with elementary, middle, and high school students, this site could also be beneficial to the mathematics method courses teacher education.
There is a concern that the website does not include any directions on how to use the animation.
The red balls do not show up when moved to the "128s" "bin."
Potential Effectiveness as a Teaching Tool
This website would be a wonderful resource to use when working with counting systems at the elementary, middle, and high school levels. Students would be able to see and hear the counting of each ball as it is placed in the binary table. They would also be able to compare the binary to the Arabic number.
Teacher education mathematics courses could use this site as an illustration of ways to use technology to integrate into the curriculum. Preservice teachers could incorporate this animation as a resource site when preparing lesson plans for their students.
It would also be helpful if the site presented teaching ideas and strategies to use with the binary counting animation.
The visual is busy with "extras" that are non-functional.
Ease of Use for Both Students and Faculty
The counting animation website has an attractive and appealing design. After the directions are figured out, the counting machine is not difficult and is fun to use. The binary and the Arabic counting systems are presented in an easy to compare format.
The users may lose some of the capabilities of the animation without the directions stated on the website.
It may be easier for the users if a message was given when the number entered will not calculate in the animation program.

Comments from Author:
The displays are only two of many, which are intended to promote visual auditory, interactive, realistic-like environments. They are intended to motivating and help in the effective learning of concepts in elementary mathematics. Those displays are part of a set which includes matching physical materials related to counting, and number bases.
