Slope
http://dmcpress.org/confs/scratch12/pdfs/slope.pdf
A
much simpler version of Green Globs.
The object is to get the highest score with
the least number of lines drawn. Scoring is
as follow: 1 pt for 1 glob; 2 pts for the
2nd glob; 4 pts for the 3rd glob; 8 pts for
the 4th and 16 pts for the 5th glob. All you
do is enter the slope number (m) and the
yintercept (b) and the line gets drawn
hopefully through many globs.

Fraction Darts
http://ciese.org/math/activities/fractiondarts/FractionDartsWorksheetGame.html
The
object of the Fraction Darts challenge is
to "pop" balloons located on a number line
between 0 and 1. The darts are "thrown" by
entering a number in fractional
form. Here is a glimpse of a game in
progress. Two darts (5/8 and 3/4) have
been thrown so far. Notice that 3/4 is too
small and 7/8 is too big. (See also Decimal
Darts)
Watch these 5th graders play Darts with a
Smartboard. [link]
