### Sample Problems for Reasoning and Proof

## Representation

### Teacher tools

### Area representations

Lynne Outhred and Michael Mitchelmore asked learners to illustrate the area of a rectangular shape. They found learners demonstrated four different strategies: incomplete covering, visual covering, concrete covering, and measurement. The drawings below show samples from each.

### Representation of relative position of objects

Illustration of Internal Representation

Actual object, real world, or external representation

### Representation of external objects with points on an other external object

What does this have to do with mathematical representations?

## Communication

Concepts and big ideas in the mathematical knowledge base

### Teacher tools

- Different ways to communicate problems with sample problems
- Ways to communicate mathematical representations as objects, properties, actions, & operations
- Graphing with line graphs as communication

## Connections and perspective

### Concepts

- Mathematical ideas build upon each other.
- Mathematical ideas are connected to other mathematical ideas.
- Mathematical ideas are connected to the world.
