Clicking on "View" at the left under "Teacher Activity" takes you to Teaching Module 1: Preparing To Teach Proportional Reasoning. This interactive teaching module addresses the necessary knowledge and skills students should master in order to understand the mathematics of proportional reasoning and scaling.

Overview

What do your students already know about ratio, proportion, and scale? Do they have the knowledge and skills necessary to understand the mathematics of proportional reasoning? Teaching Module 1 focuses on eight skills students should master before exploring Scale City:

Division of whole numbers

Simplifying fractions

Developing an understanding of proportional relationships

Multiplying mixed numbers

Dividing fractions

Understanding percent

Ordering decimals

Metric measurement

The module features brief videos of students answering questions that enable you to gauge their knowledge and skills in the above areas. As you view the videos, you will be asked to consider whether the students seem to have mastered the topic or whether misunderstandings still exist. You'll see one teacher's approaches to help the students develop these understandings and skills, and you'll reflect on the questions and teaching strategies you might use in similar situations.

The content of this teaching module is presented in multiple ways:

Video

Video links include a title and length. Clicking on the link will open up a new window. If you encounter problems such as stopping or skipping, the video may need more time to buffer. Just pause the video until buffering is complete.

Discussion/Reflection Questions

This teaching module includes multiple opportunities for you to write answers to reflection questions.

If you are using this resource with a partner or professional learning community, you might just type a very brief summary of your discussion in the box. If you are going through the module individually, you should type a longer reflection.

You will have an opportunity to save your responses by clicking on the "save notes" button. The text will be stored and available to print when you complete the entire module.

Quiz Questions

Multiple choice questions provide an opportunity for you to check your own understanding of the mathematics. Click on the link under "Check yourself" and the question will pop-up in a new window. The questions are written with teachers in mind—they aren't very easy! Each question includes an explanation for each of the answer choices given.

Common Core State Standards

The new mathematics standards are provided for each of the mathematics skills explored in Teaching Module 1. Click on the link and a window pops-up with the standards that correspond to the skill and grade level.

Scale City Resources

Links to the Scale City resources referenced in this teaching module are provided as needed.
