Hi Reggio, I am not to familiar with excel but love the idea that it does all the math! did you make your own chart or did you use a template?
Made my own ~ it is really easy to use. However if you are not familiar with Excel most local libraries offer 'free or cheap' classes on how to use it ~ that is how I learned all the cool things it can do for 'small businesses'
Children construct their own intelligence. The adult must provide activities and context, but most of all must be able to listen. Children need proof that adults believe in them. Their three great desires are to be listened to, to understand, and to demonstrate that they are exactly what we expect."
