Base 10 Multiplication: 
The purpose of these programs is to teach the method of base 10 multiplication for successively more complex problems: 1 by 4, 2 by 4,3 by 4 and 4 by 4.  A random problem is generated.  The student can then step through the method one step at a time by clicking the “next” button.  Alternatively, or in addition, the student can try the problem on their own and check their answer by clicking “Show Answer”.  The diagrams below illustrate a 2 by 4 case.
