I ran a mimio course the other day, and by the end of it I realised what the 'big hurdle' teachers have to get over! Replace what you do on the whiteboard in your classroom with your mimio/IWB software! If you are modelling your story writing, use the mimio/IWB so that you can save what you have done and revisit it the next day. I remember a few years ago it was custom to write your daily stories on large sheets of paper, fasten them together and they would become a reading activity for students. Do the same with your day to day modelling, save it as your 'Writing Modelling' file, add a few graphics or photos and turn it into a reading activity, or save it as a proof reading activity.
I was in a classroom the other day and saw that the teacher had drawn a numberline on her small whiteboard that was at her teaching station, and written the exercise.
I suggested to her that she create a numberline suitable for her children's level in IWB software, save it to a gallery, and start a numberline file that she could archive and use over and over again (and add to). It is simple enough to create your own numberlines (if there is not already one in the clipart libraries, check Mathematics, or check online in the Softwares website) by using the tools that come with the software. Once you have created the numberline, group it so it won't come apart and add it to your Maths Library in your IWB software. Turn on your Grid (usually in the View Menu) to make it more precise.
