Digital scrapbook freebies aren't just for scrapbookers, or those with expensive programs. Using some very simple techniques, you can use them in your homeschooling and so can your children.
The first thing you need to do is look at what you have available on your computer for software. I have a laptop that I purchased late in 2006, and it has Microsoft Digital Image (Starter Edition, which is basically a trial version). I used this to make the samples I will show you in a moment. Don't worry if you don't have this though, all you need is a basic wordprocessing program that will allow you to move things on top of each other (bring forward, bring back). The other option would be to dowload something like Open Office, which is a free office software package that is comparable and compatible with Microsoft Office. If I were using Open Office, I would choose to use either the word processing portion, or their Draw program (similar to PowerPoint).
The second thing you will need is some digital scrapbooking freebies. You can get papers (ie: backgrounds) as well elements (ie: buttons, little doo-dads, etc). Where do you get them? A basic Google search will net you thousands of sites. Some you will have to sign up for a free account, some will allow you to just download them.
Here are a couple samples I did up in less than half an hour using some freebies from online. It will obviously take your child longer, depending on their ability on the computer. It may be helpful, until they are used to doing it, to print up directions on how to do different things (ie: inserting picture, moving a picture or resizing, inserting text boxes, etc.). As always, click on the picture to make it larger.
