I don’t think this hardware recommendation would compete with SCM in any way and should be ok. If not, they are free to remove my post as I am not trying to break any rules, but just help and encourage other moms.
First, I have a ASUS computer than runs Windows 8 and so I had to buy a dongle that was compatible for my computer so that communication wirelessly would be possible. The dongle is a cable that has a HDMI plug on one end that plugs into the back of your tv and then it has a USB plug on the other that also plugs into your tv. The USB portion is its power source. My TV is older and doesn’t have USB plugs, so I just used an iphone USB power plug and have it plugged into a power strip. Here is a link to amazon where I bought my dongle. (That name just cracks me up….makes you feel like you are saying something naughty! 8-P)

The dongle simply projects my computer screen onto the tv and so anything I can do on the computer will be seen on the tv. This allows kids to sit anywhere in our kitchen, living room, or dining room and they can follow along.
Here is a link to the document camera I bought, just in case others find this post helpful.

The document camera comes in handy in several ways by allowing the kids to see the pages of the book I am reading without having to sit right beside me. They will do legos and can easily look up to see pictures or if the story gets good, I will catch them following along as I read, which I love. I have also been known to play reading games with them if I feel they are just not engaging for some reason and so I will read some and then I will just randomly and then one of them will pick up where I left off and then they will stop randomly and the next one has to pick up and read. This makes the follow along to “play” and it causes them to get engaged and they get some experience reading out loud too.
If I have a worksheet I want to go over orally rather than have them each do it, I simply use the camera to put it up on the tv and then I cover it with a clear sheet protector and then I can fill in the answers as they give them and I do not have to write in the book or on the worksheet. This way I can sell the book later or keep for future grandchildren if I want.
I did this mainly though to save a huge amount of money on our Language arts curriculum (Michael Clay Thompson’s) anyway, it calls for each kid getting their own set of books and would just cost a fortune. So, I can just buy the teacher’s manuals and project them as I read and the kids still get the benefit of being able to follow along and If there is a page with answers, then I use a piece of scrap paper to simply cover them. I saved enough in one year off that curriculum to cover the cost of both the camera and dongle with a lot of change left over.
We do Fred math as a family and I can read the chapter and then have the kids copy the questions and answer them on their own and then we go over the answers, which saves time rather than have each kid do the chapter independently and is much more fun. Oh the laughter we have with FRED!!
Anyway, hope this is what you were looking for and I hope you find it helpful.
