Modeling with Math

“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

Modeling with Math

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

Modeling with Math
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.
