Dartboard (Addition with numbers and doubles of numbers. Use 1, 2, or 3 addends
(or their double to create a sum.) http://www.bbc.co.uk/schools/numbertime/games/dartboard.shtml
Reach a target score by
placing darts on a dartboard. Please note that this game does not use
click and drag. The player should click once on the dart to attach it to
the cursor. Then move the cursor to the space they want it to land in and
click a second time to detach it.
The game reinforces doubling and adding doubles for a wide range of
1- where the target score is achieved by doubling single numbers.
Level 2 and 3-taks the learning outcomes further by doubling up two or
three separate numbers and adding them together to reach the target
score. For these levels, the numbers selected will appear in the sum at
the bottom left of the screen. The total scored is shown every time the
player presses the equals sign.

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.

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.
Reviews the terms and rules and gives examples with feedback.
