I loved the addition of the interactive whiteboard to my classroom about ten years ago. I embraced the use of computer technology from when I bought my first home computer in 1985 and first used computers in my classroom in 1986. The interactive whiteboard was a way of making use of the technology inclusive. Instead of one or two children taking a turn on the computer while the rest of the class were engaged in other things, we could all be involved at the same time, if desired.
I used the interactive whiteboard with the whole class for introducing topics, brainstorming ideas and explaining concepts. It was great for modelled writing lessons and collaborative reading. I found it particularly useful for demonstrating the processes to follow in the computer lab.
I used some purchased software, but also spent a lot of time creating activities to teach or practice particular concepts or skills. Versions of many of these lessons are now available here on readilearn.
