Nothing like a good criminal investigation to liven up math class!
CSI: Pre-Algebra is a collection of nine different algebraically inspired mathematical puzzles with a little international pizazz. The nine puzzles intend to target specific Pre-Algebra units and add a little flair to the ordinary challenge question.
Save by buying the entire bundle! Each of the 9 projects is sold separately for $5. So at $30 you get a 33% discount!
