Tool: Place Value Mathlets - Dave Posner
http://mathforum.org/mathtools/tool/235537/
A collection of animated JavaScript applets for explaining the concept of place value and 
base 10 counting. The collection includes 
Grouping by Tens, Grouping Tens and Hundreds, Tokens for Groups, Counting Powers of 10, 
Uniform Tokens and Base-10 Clock.

Tool: GCF/LCM Calculator - Modified by Jeff LeMieux
http://mathforum.org/mathtools/tool/235355/
This script takes several numbers and calculates their greatest common factor and least 
common multiple. This script is a visual modification of the original by Winston Smith (noted on page).

Tool: Area of a Circle Calculator - MathVine
http://mathforum.org/mathtools/tool/235285/
This is a calculator for area of a circle, which allows students to enter the radius or diameter. 
It then shows the solution steps to solve the entered problem.

Tool: Base 10 Addition Mathlets - Dave Posner
http://mathforum.org/mathtools/tool/235536/
The idea for the one, two, and three place addition mathlets is to show the steps in the base 
ten addition procedure in conjunction with a model. Each time the mathlet is run (by clicking 
the "New" button) a randomly generated problem is presented in both forms. Each click of the 
addition button shows one "step", i.e. for one place value, in the process. So the first click shows 
the one's place addition with a possible carry. The second show the ten's place addition, if any, 
and the third click, if necessary, shows the hundred's place addition, and the fourth click, 
if required, adds the thousands. Between steps the addition button changes color to indicate 
it is ready for the next step.
