In 2012 Texas adopted new standards. They are being applied to high school mathematics this year in our district. There are seven process standards that are the same K - 12. In that set of seven, at least 3 relate to this habit:

(D) communicate mathematical ideas, reasoning, and their implications using

**multiple representations, including**

**symbols, diagrams, graphs,**and language as appropriate

(E) create and use

**representations to organize, record, and communicate**mathematical ideas

(F) analyze

**mathematical relationships to connect and communicate**mathematical ideas

Multiple representations has been a strong emphasis for some time now. Even popular major textbooks identify clearly the exercises that ask students to look at math from multiple representations:

A popular problem solving organizer asks students to represent the problem using a picture, a table, a graph, and an algebraic model.

In addition to these forms of representation, we use manipulatives even in secondary math. From MTBoS bloggers, some examples include:

- Algebra Tiles and Completing the square from Julie
- Legos and Feasible Regions from Fawn
- Skittles and Exponential Growth and Decay from Sarah

We also use media - pictures, video - to represent mathematics. A couple of great resources include Estimation 180 and 3-Act Tasks.

When you think of representing math non-linguistically, what tools do you hope to find?
