Teach Kids Christmas Symbols with PowerPoint


Kids get thrilled with the coming December 25. It's big Christmas! Santa Clause, advent wreath, magic chimney, decorated trees, jingle bells, and inviting gifts from a long stocking that appeals! Children love all things Christmas.


But how much do they know about Christmas and its history? At the festive time, some curious kids may ask, "Mom, where is Santa Claus from?", or "Dad, who is Mary?" Intelligent parents are always there to answer such questions. Highly responsible dads and moms, however, would also plan a lesson on Christmas symbols in paper or PowerPoint as well as gift shopping for the kids, to teach them to remember - remember the glorious holiday of Christmas. After all, it is not wise that your kids art enjoying the Christmas holiday without a sense of its origin.


The Benefits


For kids living in an era of media technology, it seems to be sensible to take PowerPoint to teach them. PowerPoint allows you to add in many colorful and dynamic elements like pictures, animations, sounds and video clips to support your Christmas story.


Compared with plain text or oral narration, the audio-visual teaching method is more effective in conveying the full message to young kids. That is because on the one hand, text or oral teaching alone cannot express exactly what a Christmas symbol means, while text with illustration and sound can quickly cast a vivid image structure of the symbol in kids' mind. On the other hand, curious children would not stand a minute for a dull lesson with text only, but they can be engaged in your story provided the text being accompanied by color and dynamic, which can be easily done with PowerPoint.


The Tracks


Now you are aware of the benefits of PowerPoint teaching, you must wonder, "How to make such a course presentation on Christmas symbols? Are there any tips I can follow for the course creation?" Generally, there is no set rule for making a course presentation since every instructor has his own style that makes a difference. If you are green to PowerPoint, read on these presentation tips for a minute, shown as below:

How to create an effective presentation


Personally, I love to share with you a step-by-step approach to making a Christmas Symbol presentation.


1. Set up the layout
Create a PowerPoint presentation and rename it as you like, e.g. "Christmas Symbols". Specify the title slide and the content ones. Pick up a Christmas PowerPoint template that suits. Click here to download a free stunning PowerPoint template for Christmas. To vary the slides with different backgrounds, browse in Free Christmas PowerPoint Backgrounds Red, Blue and White.


2. Sift out useful content
Draft the story of Christmas symbols in Word. Remember to enable the spelling-checker to avoid a vocabulary error. Google for some free images for each symbol and edit them with Photoshop or else tool. Single out a soft sound track, or even a video clip, to vivify the Christmas presentation. From all the resources related, sort out those that best fit your presentation.
To get inspired, refer to Learn Christmas Holiday: 15 Christmas Symbols You Should Know


3. Organize the elements
Once all the specified stuff is imported to PowerPoint, arrange them in a logical look. You can consider using a chart to make a comparison of two or more symbols. Don't have too much text within one slide. 3-one is good, i.e. one image for one symbol, and one slide with one image. Minimize the sound icon if you don't want it to appear during slideshow. Also, adjust the frame of your inserted video until it runs perfect.


4. Don't forget Animations
Kids like lively things. So make best use of PowerPoint key features like animations, transitions, and even SmartArt. Meanwhile, remember the saying, "Too much good makes a thing bad". Use the dynamic effects in a moderate way.


5. Save it in Safe
After final rehearsal, it's time to save the presentation to storage. Oops! You don't have a home projector to show it to the kids! Got a TV and a DVD player? That's enough. You can burn the presentation of Christmas Symbols onto a DVD that can playback on a home TV, with an affordable converter like Moyea PPT to DVD Burner (3 Editions as the Pro, the Lite and the Edu). Click here to learn how to burn a Christmas PPT presentation to DVD


One Christmas Eve, after dinner, sitting with the kid(s) at TV, you can remote control the PowerPoint DVD and teach Christmas Symbols and their significance. Let your kids learn and enjoy the holiday.

Convert PowerPoint to Flash Video (FLV), Easier than You Can Think

Many companies and none-profit institutions do appeal to both PowerPoint and flash videos. To make further reach to a presentation, you may consider converting the PowerPoint to flash video (.flv).


Don't have an idea of flash video?


Here's a brief introduction.
Flash video, short for FLV, is a media file format used to deliver video over the Internet using Adobe Flash Player version 6-10. Flash Video content may also be embedded within SWF files, within which the audio and video data are encoded in the same way. Flash video is viewable on most operating systems, via the widely available Adobe Flash Player and many other third-party players like MPlayer, VLC media player, QuickTime and Moyea Web Player. With small size, flash video has established its name as the choice format for embedded video on the web. It is used by web services like YouTube, Google Video, Yahoo! Video, metacafe.



What Can You Benefit from converting PowerPoint to Flash Video?



1 1. Be friendlier to your audience. There are much more computers installed with a flash player than a PowerPoint program compatible with yours. That is, your audience will get a quick access to your presentation masterpiece in Flash Video. And, a flash video online is more intuitive than a PowerPoint presentation to download.
2 2. Smaller size makes more sense. A PowerPoint file turned in flash video is much smaller than its original size. A credit to fast web distribution. To insert a presentation to your blog, a web video service like YouTube, you'd better reformat it to such swift FLV file.
3 3. Hassle free from PowerPoint emailing. Many users suffered from emailing a clumsy PowerPoint file to a client or a friend. With the presentation in small flash video via an online web service, they don't have to email it while the viewers won't bother to wait and download.
4 4. Safeguard your presentation work. A PowerPoint file is liable to being stolen by unwanted hands, e.g. your rival companies, with minor modification. When you finalize it in flash video, one cannot edit it with ease. Your content will be safer during web distribution.



What Tool You Need to Convert a PowerPoint presentation to FLV?



When Google or Bing, you may be dazzled by a cluster of programs that claimed to convert PowerPoint to flash video. If you are not to bother to a fussy trial of each program, you can trust me with this dedicated PowerPoint to FLV converter - Moyea PPT4Web Converter. It is one of the pioneer programs that shows proven performance in converting a PowerPoint presentation to flash video without any loss of original effects.

Before the conversion, check your presentation carefully, for instance, the text fonts, the slide transitions, animations, inserted sound or movie clips, until satisfying.


Below comes a short guide of converting PowerPoint to FLV with Moyea PPT4Web.

Step step 2 Select the output as FLV or any other flash player supported file formats (MP4, MOV, 3G2, 3GP). Customize each output parameter if necessary. You can also follow the Web Player icon link to get a flash player if there isn't one on your local drive.
Step step 3 Click Start to start converting your PowerPoint presentation to Flash Video.


Very simple, isn't it? In a minute or two, you will get a flash video out of your PPT file. Now, it is a snap for you to upload the flash video slideshow on the Web, distribute anywhere possible to reach more audience.
