In the community learning environment. educators want the student to not only find things but be familiar and comfortable in the store, whether it is some place they go with their family or not. While this is not necessarily "tech" It is a method I have used with a number of students and had my first opportunity to share with educators today.
The map card is a simple 3X5 index card that the student cuts out items from the adds for that store (sometimes the store logo as well) and while visiting the store adds the location (aisle: letter and number) corresponding to those items. Parents students and educators alike have had real success with this idea.
Thank you parents, educators (Kerrie, Carol, Tracy and Mary) for hearing me out and giving this a try
