Diffy http://nlvm.usu.edu/en/nav/frames_asid_326_g_1_t_1.html
A virtual manipulative for practice of subtraction (taking differences).
Starting with four black numbers in the corners of a black square,
students find the differences (larger minus the smaller) between the pair
of numbers on each side of the square. The computer is programmed to not
accept an incorrect answer, so that when an incorrect difference is
entered, the number field is blanked out and the student can try again.
Options: Whole Numbers, Integers (positive and negative),
Fractions, Decimals, Money (When working with Fractions, the difference of
two fractions is a fraction that can be written in many different ways.
Type in both the numerator and denominator before pressing Enter, but you
can write the fraction in most any equivalent form. A difference of zero
can be written as 0/1.)

Exponents
and Prime
Factorization
Exponent
PowerPoint Lesson (http://mathforum.org/te/exchange/hosted/link/LFTMZ-Exponents.ppt
This is a PowerPoint lesson on exponents designed with the middle schooler
in mind. The lesson uses color, sound, and animation to effectively
illustrate necessary concepts and procedures. An analogy between repeated
additions (e.g., 3 x 5 = 3+3+3+3+3) and repeated multiplications (e.g., 3
^ 5 = 3*3*3*3*3) is used to motivate and explain the concept of exponent.
The times sign (x) is used for repeated additions, and the caret (^) for
repeated multiplications. Students first practice using the caret on their
calculators and by hand. Then the positional notation for exponent is
introduced with further practice. Optional extensions are included for
zero to the zero power and negative exponents.
