The Problem Solving and Communication Activity Series Make a Mathematical Model

# Make a Mathematical Model

Organizing quantities and relationships into a mathematical model (equation, table, algorithm, etc.) is one of the most powerful, and most challenging, problem-solving tools.

We support students to build on their skills and noticers (Understand the Problem) and organizers (Guess and Check, Make a Table) to list the quantities and relationships they see in the problem, and then support them to either "build up" several relationships or "break down" a big-picture sense of the problem to develop a mathematical model.

## Facilitation Questions

• What are the quantities in this problem?
• How can you write the relationships between them?
• Could you build those relationships into a model?
• Can you think of the big picture and break it down into a complete model?

## Recommended Library Problems
