Falling Erasers -- download
here
This fast paced game supports knowledge of multiples of numbers
2 through 9.
Each time the student plays, a random number between 2 and 9 is
chosen.
Erasers drop at varying speeds. The trash can is moved with the
right and left arrow keys.
The
object of the game is to catch the "good" erasers (which
are multiples of the particular number), and let the "bad"
erasers fall the floor. Scoring depends on which are caught, and
which are dropped. The score increases or decreases by a multiple
of the particular number.

This is another fast paced game where the eraser is constantly moving.
The student changes direction with the arrow keys.
There are 3 levels of the game. In the first, the eraser is to be
guided over fractions that are either greater than 1/2 or less than
1/2 (this is randomly determined, so it will vary from play to play).
These fractions are all programmed by me, to keep the fractions
fairly easy.
In level 2,
the eraser is to be guided over fractions equal to or greater than
1/2, or equal to or less than 1/2. This is randomly determined.
The actual fraction values are also randomly determined, which adds
variety and difficulty to the game.
In
the advanced level (level 3), the fractions are randomly determined,
also the value sought is randomly determined. Level 3 is particularly
challenging.
In
all 3 levels, incorrect passes with the eraser cause the fraction
to turn red, to teach as the student plays the game. Correct passes
"erase" the particular fraction.
