Learning Math: Number and Operations

About the Learning Math Courses

When teachers have a deep conceptual understanding of mathematics, it can help their students develop strong mathematical skills and knowledge. Learning Math is a series of five multimedia, college-level courses designed to teach mathematics content to elementary and middle school teachers. Organized around the content standards developed by the National Council of Teachers of Mathematics (NCTM), the courses cover Number and Operations; Patterns, Functions, and Algebra; Geometry; Measurement; and Data Analysis, Statistics, and Probability.

Overall Objectives

  • To help teachers better understand mathematics content
  • To provide engaging explorations of mathematics using video, interactive activities, and problem solving
  • To encourage teachers to view mathematics as more than rote sets of rules and procedures

How to Use These Courses

Each Learning Math course includes sequentially organized problems, video viewing, interactive activities, readings, and homework. The multimedia elements of the course create an exciting environment for probing mathematics content. The course can be taken entirely on the Web, followed in a print guide, or completed using a combination of Web and print.

The following sequence of activities will give you a sense of what you will do as a student using Learning Math:

1. Watch the session video in its entirety. You can watch the video before you begin the session to become comfortable with the material, or you can view the video after completing the session (so as not to view answers to problems).

2. Do problems sequentially. Each session is divided into several parts indicated in the tabs along the top of the page. The problems are numbered within each part. (e.g., Problem A1)

3. If you are having difficulty with a problem, look for a Tip icon.

4. Find the solutions to problems in the Solutions section below.

5. If you want a more rigorous challenge, try out a Take It Further problem.

6. Read the Notes as you go along, to establish a context for the content and for suggestions on doing the activities in groups.

7. Watch video segments strategically placed throughout the session by fast-forwarding or skipping to the approximate time code indicated. Use the time codes provided to locate the segment.

8. Do homework problems and readings (available as PDF files online) at the end of each session to reinforce your learning.

Ways To Take Learning Math
Learning Math was flexibly designed for a variety of users and situations. You may choose to work through the sessions on your own, in a study group, or as part of a facilitated, face-to-face, professional development workshop.

Facilitating the Course
You can prepare for facilitating the course by reading through each session and its “Notes” section prior to meeting with your group. Reading through the material will help you become clear about the activities, plan how much time you need to spend on each one, and pull together necessary materials. The course is designed for use by an individual, but the Notes may suggest ways for groups to work through the sessions.

Course Components

Each Learning Math course is comprised of 10 two-and-a-half-hour sessions. The first nine sessions are devoted to mathematics content; the 10th session covers classroom applications. Concepts are developed within and across the sessions, and the sessions increase in difficulty as they progress. Each session includes reading, problem solving, and group or individual activities that are available on the web and in print, and a half-hour of video viewing, available on the web. There are additional problems and readings to complete for homework.

The following components are in each course:

Key Terms
Key mathematical terms relevant to each session are listed at the beginning of that session. These terms are divided into two parts: terms that are new in that session and terms that were introduced in a previous session. Definitions for key terms may be found by clicking on the Glossary link.

Notes can be used by facilitators, study groups, or individuals working alone. They provide extended information about the topics presented in the course, including help for dealing with stumbling blocks that may come up and recommendations for different ways to approach the content.

Each session contains mathematical problems to be solved individually or by groups. Problems build upon previous concepts and increase in difficulty as the course progresses.

Take It Further
The problems marked “Take It Further” are optional and are not counted as part of the two-and-a-half hour time-frame for each session. These problems are designed for individuals who would like to explore a topic in greater depth. They are often more difficult than the other problems in the session, and they may introduce new information or concepts not previously discussed.

Each session in the course includes at least one interactive activity. These activities help you learn new mathematics content or reinforce existing knowledge through hands-on exploration directly on the Web. The interactive activities require the Flash plug-in, which you can download for free from Macromedia’s Web site. There are also non-Flash versions of each activity that don’t require the Flash plug-in.

A Tip is provided at the end of many problems in the sessions. The tips are hidden so those who prefer to try to solve the problem without any help can do so. To view the tip for a selected problem, click on the “Tip” button. To hide it, click “Close Tip” at the end of the tip text.

A solution is provided for every problem in Learning Math, with the exception of a few open-ended questions. When solving a problem with multiple parts, consider writing down your answers to all of the parts on paper first before checking the solution, because the answers to each part of the problem will be visible at once on the solution page.

Write and Reflect
Open-ended problems that encourage you to think about a particular concept include a Write and Reflect button rather than a Solution button.

Session Videos
Each Learning Math session includes viewing a video that is available on the course website. The videos feature K-8 teachers working on the Learning Math course materials in a workshop with a facilitator. The videos for the nine content sessions show onscreen participants as they are introduced to the concepts, work through the problems, sometimes struggle to reach an understanding, and then reflect on what they have learned. At the end of most videos there is an example of how the content from the session is applied in a “real world” situation. The videos for the 10th session show participants from the videotaped workshops as they apply the content that they have learned back in their own classrooms. You may choose to watch each of these videos before or after you work on the associated course session.

Video Segments
Each session includes short excerpts from the associated video, which you watch (or review) and reflect on to see how the onscreen participants grapple with the same or similar problems and concepts you encounter in the course. The segments are available on the course website, if you are watching the videos online.

Each session includes approximately 45 minutes of homework problems and/or reflective writing assignments that reinforce the session’s content.

Readings from journals and books are cited at the end of some sessions. They are available on the course website as downloadable PDF files.

Technical Requirements

To use the Learning Math courses online, we recommend the following:

Internet access:
Minimum 56K modem connection, but ISDN or high-speed connection is recommended. The slower your connection, the longer it will take to load larger features, such as the Flash activities. To view the video programs and video segments online, a DSL connection, cable modem, or LAN connection to a T1 line or greater is required.

Web browser:
Internet Explorer 6.0 (or a higher version). (Javascript should be enabled, if your browser allows you to disable it.) Text fonts and colors, and many features, such as hidden Tips, may not be displayed correctly in older browsers.

Here are links to sites where you can download (for free) the plug-ins you’ll need to get the most out of the courses:

Adobe Acrobat Reader for viewing the Readings in the Homework sections

Notes on printing:
If you are having trouble printing some of the course content pages, you may try doing one or more of the following (from the “Print Preview”, “Print…”, or “Page Setup…” menu):

• Turn on “Shrink to Fit” mode (IE 5 only)
• Print the page in “Landscape” mode
• Reduce the scale of the printer output
• In the Measurement course, certain PDF documents are drawn to scale. When printing them, be sure that the Acrobat print dialog box settings for page scaling or shrinking oversized pages are turned off.
