### PRODUCT DESCRIPTION

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.

Save by buying the entire book! Each of the 9 projects is sold separately for \$5. So at \$25 you get over a 50% discount!

Each puzzle has 6 “scenes” which will uncover a mystery variable. These six mystery variables will be used to decode a cryptic text message and if everything is correct, the result will match one of the six suspects.

In this product you will receive ALL NINE different puzzles..

Unit 1: Operations & Expressions: Order of Operations, Verbal Expressions, Adding & Subtracting Integers, Using Formulas, Combining Like Terms

Unit 2: Factors, Primes & Multiples: Greatest Common Factor, Least Common Multiple, Prime Factorization, Divisors

Unit 3: Equations & Inequalities: One-Step and Two-Step Equations and Inequalities, Word Problem Application

Unit 4: Decimals: Operations with Decimals, Equations with Decimals, Place Value, Rounding, Number Line Estimation

Unit 5: Exponents, Roots & Scientific Notation: Exponents and Roots, Converting Scientific to Standard Notation, Evaluating Expressions, Compound Interest, Square Root Approximation

Unit 6: Fractions: Operations with Fractions, Equations with Fractions, Equivalent Fractions, Writing Fractions from Real World Situations, Common Denominator

Unit 7: Ratio, Proportion & Percent: Converting between Ratio, Percent and Decimal, Similar Figure, Scale Factors, Percent Word Problems, Simple Interest

Unit 8: Coordinate Plane: Ordered Pairs, Sketching Functions with Tables, Linear vs. Non-Linear Functions, Non-Euclidean Planes, Translations

Unit 9: Data Analysis & Probability: Permutations, Mean, Median, Mode & Range, Histograms, Box and Whisker Plots, Conditional Probability, Theoretical vs. Experimental Probability

Each puzzle has an ANSWER KEY included.

If you are teaching 7th or 8th Grade and are looking for fun review activities and enrichment problems, I have you covered. Student Satisfaction Guaranteed or I'll give you your money back.

I have used these puzzles with much success with a variety of students. Enrichment for advanced students. Review for state graduation exams. The puzzle solving hook engages many different students in solving traditionally mundane problems. Be the cool teacher :-)

My students loved these activities! I have used them with my 7th grade Pre Algebra students as review of material at the end of units. I am planning to use them at the end of the year with my 6th graders to prepare them for their final exams! The activities are engaging, fun, challenging, and accurate. We even made a world map and tracked the locations of the crimes, including print outs of the crime locations! I highly recommend this product!

I just wanted to leave a comment about the lesson on multiples and factors. When my students got to Scene #6, they figured out that since they already knew what M was not zero, the answer to Scene 6 must be that L=1. Therefore, there was no need for them to do any of the math on that page. I have really enjoyed doing other CSI units with them. I hope that you can correct this issue so the kids can't use logic to avoid practicing the math. Thanks!
Logic is math! :-) I will look into that. I just always required to see the work for each problem as part of their "Case against the suspect". :-) Thanks for the feedback.

Very thorough and very fun! I can't wait to start using this with my 7th graders.

Does this come as one 127 page file? Or are their 9 separate files seperating the 9 units?

Thanks,
Tim
It is one PDF, but the Table of Content and page number option should make it easy.
I just purchased the pre-algebra CSI set (8/30/13) and going through the packet I noticed there is info missing from most of the mysteries. Example: Unit 1 operations and expressions, PGA tour puzzle is missing the players names. Instead, it only has gradiated black and white blocks.
There are more puzzles with blocks instead of info but I won't list them here due to space. Is there a way I can get a correction? Do I need to list all the puzzles that I am missing info from?
No you definitely do not need a list :-) Some have had issues opening the files on applications other than Adobe Reader. If you use Adobe Reader and it is still a problem, email me at 21stcenturymathprojects@gmail.com and I will send it as a Google Doc.
I teach pre-algebra and Algebra I in a small charter school combo class. The challenges completely different, or could I use pre-algebra for both?
You can certainly preview the files. You can see pretty much everything. I always find it hard to answer these types of questions because every class is different and they may need different things. There are projects I have posted here that I used in a 9th Grade class (with low skills) and I found out a 5th Grade teacher used it with her gifted class. So it all depends :-) Hope this helps!
