Details:

These activities are contained in five Paint files. For use on a school local area network,these files should be installed is a shared, read only directory on the server (WSD#1 uses S:\2Student).  If you wish to download any of these files, click on these links:
BASE2.BMP, BASE3.BMP, BASE 4.BMP, BASE5.BMP and/or BASE10.BMP. 

After launching Paint and opening the file, children can be directed to solve addition   (orsubtraction) equations in whatever number base the blocks indicate.  A base ten example,17 + 9 will be shared here:
