Speed with these types of skills increases the amount of material which can be
completed by any student in a given amount of time. The ripple effect into
mathematics related areas is astounding. Students, with good mental arithmetic
skills are also much more confident in mathematics.

Technical Remarks:

To ecourage students to practice with these skills on a regular basis, sound and
animation might be included.
Used in course? Yes

Great for testing how fast students can do simple mental arithmetic. Tristan De Frondeville has written a paper describing his use of this applet in his classroom. Kids that can add ""8+6"" in less than 3 seconds do have an advantage when they get to algebra, etc.
