The Backwards Guessing Game
This is a Java applet so you can play against the computer online. The computer selects a number between 1 and 1000 and you must "guess it"; the computer will tell you if your guess is too high, too low, or correct. Space is provided to write notes, and the total number of guesses is displayed. Use The Super Guessing Game to see the computer's strategy for guessing YOUR secret number.
Jordan Hiller

Practice counting while developing point-n-click skills with the mouse. The java applet will only draw the lines when numerical order is followed; when all the dots are connected the picture will appear in color. Several different drawings are available.

Interactive Mathematics Miscellany and Puzzles
This site is filled with a wide variety of challenging and enjoyable math activities. See if you can solve these Interactive Math Games; try your skill at the geometric Eye Opener Series. Can you beat the computer at The Game of Fif, or figure out the solution to the Four Knights? Try the classic puzzle, The Tower of Hanoi; you can set the number of disks yourself to make the puzzle easier or more difficult (the recurrsive solution is included). Don't worry -- if you get stuck on one there are many others to try! See if you can figure out which types of puzzles are easiest for you to solve... which skills do they require? Then compare them to the puzzles that are more mind-boggling for you. And remember, what's obvious to one person may be confusing to the next. . . .
