### Zombies and Math (AAH!!)

Zombies and mathematics looks like it would be two things that didn't quite go together.  Andrew Miller had a project-based learning project about Zombie-based Learning.

With math and zombies most of the material has to do with diseases that increase at an exponential rate.  Students could analyze different population centers and predict its spread using exponential functions.  They could determine when everyone is infected and map the spread using the math data they calculate, or even explore the rate of decay.  Students could also investigate what happens when a certain number of people are vaccinated to help prevent the spread.

These are some ideas that have been implemented as part of a PBL project or would be a good entry point for zombie-based learning across the curriculum.

### English to Spanish Math Glossary

Featured in today's post is an elementary school level mathematics glossary for English to Spanish glossary.  This works great for many teachers who teach in a ELL math classroom or in a high population of Hispanic students.  Some of these glossary terms work great in middle and high school math classrooms.

algebraic expression       expresión algebraica
algebraic patterns           patrones algebraicos
algebraic relationship      relación algebraica
algebraic relationships    relaciones algebraicas
algebraically                  algebraicamente

algorithm                       algoritmo
divide                           dividir
dividend                       dividendo

geometric fact              hecho geométrico
geometric figure           figura geométrica
geometric pattern         patrón geométrico
geometric solid            sólido geométrico

### Paper Doll Math

I have recently blogged about Ada Lovelace and her paper doll which could be used as a history piece in a history of mathematics center that students can learn about mathematics and how math was developed back in the day.  Today, are some activities that you can use in your classroom that revolve around paper dolls and mathematics.

Patterns: Figures alternate, for example: right arm up, left arm up, right arm, left arm.

Reflections: Students love that every doll is a flipped copy of the one next to it.  Technically, that's called a reflection, one of three kinds of geometry transformation students study in elementary school, the other two being rotation and translation.

Powers of Two: Fold the paper twice, you get four figures.  Fold the paper three times, you get 8 figures.  Fold four times, you get 16 figures.  Every fold is a power of two of the figures.

Multiplying fractions: Every time you fold, the dolls become half as wide.  That's a visual illustration of what it means to multiply a fraction, in this case x 1/2.  Or, if the first fold divides the paper in half, and the second fold divides it in quarters.
