Nothing like a good criminal investigation to liven up number sense!
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.
