Suggestions on how to use this flipchart:
Using the Desktop Annotate feature on the Interactive Whiteboards, facilitate this lesson as a whole group. Each slide has school icons that you could use for your school store. They differ from the actual lesson, but I had these cutesy pictures already and wanted to use them! You can print these slides out 2 per page and print them front and back (to save paper of course :D) so the students have the same items as you.
Also could be used as a center where the students redo the activity. The students can use the right side of the slide as a work mat with their pennies and dimes.
These would be ideal to use with SmartPals, or page protectors and wipe-off markers. You may want to put the prices in for the students before if they are beginners (and to avoid getting answers where grouping is necessary.)
