“Mathematical modeling is the link between mathematics and the rest of the world.” (Meerschaert, M., Mathematical Modeling,Elsevier Science, 2010)

The process of beginning with a situation and gaining understanding about that situation is generally referred

to as “modeling”. If the understanding comes about through the use of mathematics, the process is known

as mathematical modeling. 

4

Modeling with MathGOAL: students pose their own questions

about the world and use math to answer those questions

TEACHER’S JOB: construct situations in which students are choosing math to better understand their everyday life

Students

Apply prior knowledge to new problems and reflect

Use representations to solve real life problems

Apply formulas and equations where appropriate

Teachers

Pose problems connected to previous concepts

Provide a variety of real world contexts

Use intentional representations

Modeling Steps1. Identify a problem situation2. Make a representation of one or more

elements of the situation3. Create a mathematical expression4. Compare results or predictions from the

mathematical model with the real situation5. Make revisions to the model if needed

Modeling with Math

Elementary Grades:

Ensure the math students engage in helps them see and interpret the world

Type of thinking required more important than the context

8

Modeling with Math

1. Give it context2. Go deeper3. Tap into resources

9

Modeling with MathGive it Context

Consider applications of the workTo think deeply, math needs to be in contextSpend less time on repetitive problemsMore time with real scenarios

10

Modeling with MathGo Deeper

Build longer problems with multiple steps and more than one question

Additional questions add depth and rigor – call upon students to demonstrate understanding over multiple skills

Tap into Resources

Task prototypes from PARCC Video Story Problems (The Tech Savvy Educator) Teaching Channel

Problems with real-world implications demonstrate that what students are learning has value.
