Feverishly writing and researching I've added quite a few products to the popular CSI collection! I still have a ways to go to publish a new eBook, but I do have 7 new Geometry puzzles. Learn some geometry while learning a bit about the world and crime scene investigation!

We start the adventure in South Africa home to the Vuvuzela and learn some of the Foundations of Geometry!

Students go to France to practice Deductive Reasoning Skills

then travel to the Caribbean for Triangle Practice

after a nice tan they go to Canada for some Similarity and Proportion problems

after a losing the nice tan they travel to India, one of the many home of Trigonometry

from there it is off to England to investigate their fascination with Circles

and most recently students will refine Area skills in the Second City, Chicago

Each of the puzzles have the same structure and can make some engaging learning that gets away from a drill and kill worksheet! Check out the previews on TPT you can see everything! Except the answer key (I think 2/3 of my blog traffic is students looking for answers to the projects :-)

You can get the Interactive & Customizable Version of CSI Geometry at my NextLesson.org store and optionally customize it for your needs.

### Person Puzzles -- Cesar Chavez -- Order of Operations

The most anxiously awaited 21st Century Math Project Algebra 1 puzzle unveiling of 2013! Come on down, Cesar Chavez!

**7-12 (Algebra, Prealgebra skills)**

__Suggested Grade Level:__**10-30 minutes**

__Teaching Duration:__**$0.75 for a 2 Page PDF (1 assignments and answer key)**

__Cost:__Cesar Chavez is one of those recognizable names that people seem to know, but have no idea who he actually was.

### CSI: Geometry -- International STEM Project

Back for more! |

Like my Algebra projects, students will work in teams to investigate the culprit of six fictional thefts. The criminal has left six messages, layered with geometry practice. Teams will work to build a case and present their findings to the court. Hopefully they are convincing enough to win the verdict.

**CSI: Geometry – Shapes, Lines & Angles (Unit 1)**

__Name:__**7-12 (Primarily Geometry math skills)**

__Suggested Grade Level:__**Distance and Midpoint, Perimeter, Polygons, Writing Equations of Lines, Parallel Lines**

__Math Concepts:__**South African Culture and History, Social Studies**

__Interdisciplinary Connections:__**2-5 Days with Optional Jury Presentation**

__Teaching Duration:__**$5 for a 12 Page PDF and Answer Key**

__Cost:__**Students build a criminal case versus a suspect using evidence from six “crime scenes”. Optional: Jury Presentation of Evidence in front of the class.**

__The Product:__What?! I can be engaged for two years now? With rigorous practice? Pinch me! |

CSI: Algebra quickly became my most popular 21st Century Math Project on TPT and remains on the top. I’ve shared my projects with a number of teachers, but no lessons get them giddy like my CSI Projects. There’s just something innate and fun about solving the puzzles and solving the crime. And with Math!

I had fans (well 4 or 5 people) ask my about when I'd expand the puzzles to other courses. So I have used my winter break to dive face-first into Geometry.

The big three! |

Bring your own vuvuzela to school! |

This project would fit nicely into a Middle School or high school Geometry class. I find that these serve well as Chapter Reviews before Tests. Do be careful about how you assign it though, given the problems unique nature, students can be confused about what to do. Given the level of your class you can drop hints and differentiate as needed. My guarantee, you’re best, nerdiest math students will love it!

Keep your eyes open for the second ever

.

__Free for Three,__**post. For three hours, I will make a surprise item in my store free. If you show up at the three hours and two minute mark, you will pay -- literally. It'd be super awesome if you'd follow me on Pinterest and extra amazing fantastic if you put a review on TPT!**__Boomdiggy__.
