### Self Assessment

### Reflections

In the video below Paul explains how he uses the camera capture tool to take a picture of a pre-image. That image is then flipped, resized and made transparent. (All of this can be done by selecting an object and going to the drop down menu.)

This method allows Paul get feedback on his work. He was able to check to see if he drew the reflection correctly.

### Perimeter

How to do it.

1. Capture the problem with the capture tool or type it in with the diagram.

2. Lock it down.

3. Make another line and label the length.

4. Use the order feature to bring it to front.

5. Now it can be moved and turned to form a line. This line is the perimeter of the distance around a polygon.

### Area

I was just reading an article about math misconceptions.

MATHS MISCONCEPTIONS*

From Teachers: January 2006 Issue 42 [UK] http://www.teachernet.gov.uk/teachers/issue42/primary/features/Mathsmisconceptions/

One misconception is about area and perimeter. This is what the article said:

Perimeter and area confuse many kids! A common mistake, when measuring the perimeter of a rectangle, is to count the squares surrounding the shape, in the same way as counting those inside for area. Now you can see why some would give the perimeter of a two-by-three rectangle as 14 units rather than 10.

How can a smartboard clear up misconceptions about area and perimeter? Well using the infinite cloner and grouping feature the smartboard can make the concepts very visual. Watch "Paul's Podcast" where he explains his thinking about area. Next week we will make a video about how the smartboard can be used to teach perimeter.

### Ways to Do Math Routines with a Smartboard

There are several math routines we do in the primary grades. This video from YouTube shows how one teacher incorporates the smartboard into her routines. You will see calendar math, a weather chart, the day of the year, money and more.

### Using Space Off the Page

This morning I am struggling with many ideas. I know that smartboards can be a powerful tool to show math representations to students. One of our schools is going to concentrate on teaching math word problems. I know from past research that the rectangular array method is a wonderful tool to understand, organize and communicate word problems. In fact the rectangular array method is a wonderful tool to understand, organize and communicate many math ideas. It is also a wonderful differentiation tool allowing students access to more abstract ideas.

Now that we have a plan (model and use the rectangular model.) I set about adding it to some of our math pages. Here are the struggles I am facing and how I solved them.

1. Too much on one page. A page filled with rectangles will not help a struggling learner. There is too much information to process. It is also very difficult to make them all fit nicely.

2. We want students to own their own learning. Having every model there might make the math too easy. At some point, when they are ready they should draw their own rectangles. Kids grow and learn at their own pace. How do you have the representation ready if they need it, but not use it if they do not?

3. Making connections and being able to transfer knowledge is a big part of learning. How do you help kids understand WHEN drawing rectangles might help them better understand a problem, organize their thinking and give them a tool to communicate their thinking? How do you help them own this method?

Watch the video and see how I attempted to answer some of these questions. Please write comments in if you struggle with these ideas as well or have any ideas.

### Cleaning a Smartboard

How do you clean the smartboard?

Applies to: All Rear-Projection SMART Board™ interactive whiteboards, SMART Board for Flat-Panel Displays interactive overlays, Sympodium™ interactive pen displays and Actalyst™ interactive digital signage. Overview

This article explains how to clean the surface of your Rear-Projection SMART Board interactive whiteboard, SMART Board for Flat-Panel Displays interactive overlay, Sympodium interactive pen displays or and Actalyst interactive overlay. Details

To clean the writing surface or screen, use Windex® glass cleaner. Just spray the cleaner on a soft cloth or paper towel and wipe the screen surface. Avoid spraying the cleaner directly on the screen, since the cleaner may damage components if it runs into the edge of the screen.

WARNING: Do not apply isopropyl alcohol, water or acetone to the back surface of the screen. These fluids could damage the diffusion coating, resulting in a permanent deterioration in display quality. If you do smudge this surface, wipe it carefully with an alcohol-free glass cleaner. Do not spray the cleaner directly onto the back of the screen. Spray the cleaner lightly on a cloth, and then gently dab the surface until the marks are removed.

NOTE: To remove permanent marker ink from the screen, use a cleaner such as Expo® Board Doctor. If you have high-odor dry-erase markers (not non-scented markers), you can cover the permanent ink with the ink from a dry-erase marker, and then wipe with a soft cloth or paper towel while the ink is still wet. If any trace of the original permanent ink remains, spray a cloth with Windex glass cleaner or Expo Board cleaner and wipe the area clean.

Sorry I have not written in a while. I was just reading the article, Digital technology could revolutionize math learning, in Education Week. I had to post this very powerful paragraph since it explains how to use the smartboard effectively in math class. For the whole article go to http://www.edweek.org/ew/articles/2008/05/07/36patton.h27.html?tmp=590369170.

Second, digital technology can provide interactive, dynamic representations to enhance conceptual understanding. These could include “definition unfolding”—one of the most important pathways to mathematical meaning-making. Being able, for example, to select “Ö3” wherever it appears on any page and have it immediately explained as “that positive number which, when squared, yields 3” could continuously reinforce the connection between symbols and terms and their mathematical meanings. Similarly, geometric constructions are much more revealing when they can be manipulated, and motion graphs are more comprehensible when they call up motion.
