As a fifth grade math teacher, I am given the task of teaching a skill (such as 4 digit by 2 digit multiplication) and then providing my students with the knowledge to apply that skill to a word problem.,
After reading a word problem about a florist that had 9 daffodils and twice as many tulips and then donated them equally to 3 parks, I began to visualize how my students might better to see the "why" in these problems if they could actually talk to a florist.
Having a variety of classroom visitors would be wonderful but a bit overwhelming. However, with technology we could bring the visitor to the classroom through such means as skype, video chat, or videoing our visitor with the use of a phone.
I believe that students would benefit from this interaction in a variety of ways. Not only would they encounter many different occupations, but they would also see the benefit of applying math skills to real world situations with real people.
