Reflection: Rigor Size Matters: A Journal Activity - Section 2: Active Engagement

 

Common language leads to common understanding. If we both use the same word, but understand its meaning differently, we cannot communicate. This is why I feel very strongly about students using the correct vocabulary when explaining themselves.  In order to be mathematically precise, as well as insuring a common language (common understanding), the teaching of, modeling, and usage of important terms is critical.

The Mathematical Practices #3: Construct Viable Arguments and Critique the Reasoning of Others, and #6: Attend to Precision both require students to use accurate language.  It is important for us, as role models, to use this vocabulary, explicitly teach it as well as support its use in the everyday classroom setting, and expect the students to communicate their thinking by using these terms in speaking and writing.

I also believe that the use of correct vocabulary terms can "demystify" mathematics for students. When children know, and can use, the mathematical terminology, asking for help or giving help becomes easier.

Size Matters: A Journal Activity

Unit 6: Unit Fractions
Lesson 10 of 13

Objective: Students will be able to create, name, and write fractions by reasoning about the relationship between the whole and a unit fraction.

Big Idea: Understanding that a whole can be defined using different fractions is a complex task for students, unless they have great tools, like pattern blocks.
