Beware Of Fake Math Modeling Problems

Here’s a question to think about: if you can completely remove a problem’s context and still solve it, can it really be mathematical modeling?

Consider the math problem below from a middle school math textbook. It uses the context of a baseball diamond to discuss rational numbers. It is listed as a “Real-World Link” and demonstrating Math Practice 4 (notice the box in the upper right).

I was watching students work on this page and wondered how important the context was to solving these problems. Then it made me wonder, “What if there was no context? What would change?” This is what the problem might look like it the context was completely removed.

Levels of Convincing

I recently attended a full day workshop with Jo Boaler where she shared a different way of thinking about convincing someone from Thinking Mathematically by J. Mason, L. Burton, and K. Stacey.  In the book, she identified three levels of convincing: Convince yourself Convince a friend Convince a skeptic   I immediately realized that this…

How do the Common Core Math, ELA, and Next Gen Science Standards Overlap?

I wanted to share a resource from Tina Cheuk out of the Understanding Language department at Stanford University who created a very useful graphic organizer to show that the Common Core State Standards (CCSS) for Mathematics, English Language Arts (ELA), and Next Generation Science Standards (NGSS) have significant overlap and can be collectively implemented for…

Comparing the Texas Essential Knowledge and Skills to the Common Core State Standards

How do the Common Core State Standards‘ (CCSS) description for how students are expected to demonstrate their mathematical understanding compare to the Texas Essential Knowledge and Skills‘ (TEKS) description?  I wondered about that question as this summer I will be doing my first workshops and presentations in Texas.  As I primarily work in California where…

Content and Language Objectives using the Standards for Mathematical Practice

Math content and language objectives can be challenging to create, especially when you don’t want to explicitly tell students what they will be learning at the beginning.  Additionally, if your school is using the Sheltered Instruction Observation Protocol (SIOP) model, content and language objectives are required for every lesson.  Fortunately, the Common Core State Standards’…

What Isn’t Mathematical Modeling?

Many teachers reading the Standards for Mathematical Practice are confused by what “Model with Mathematics” (Math Practice 4) means.  I define mathematical modeling as the process of taking an often real-world context, turning it into something you can manipulate with mathematics, and then returning to the context with the new knowledge.  For example if you want…
