Try some of the following links for information and then feel free to ask further for something you can not find:
A "pear island?" Is your map supposed to represent Prickly Pear Island in the West Indies?
To make a 3-dimensional topographic map, you'll need to show depth -- perhaps with the construction paper. If it's only a topo map, then the string can be used to show the contours.
Is this the kind of topo map you have in mind?
It is somehow like this but does bnot have so much contours. It is like a two different island linked together by a river by the sides, one river on the top map beside and the other bottom beside. I f you don't understand what I said you can tell me. It is a project that i have to use two foa boards, one green, one blue. one represents the river and the other island and i have to cut out the shape of the map that I was given on the green foam board, stack it together and paste it on the blue one. the only thing i dont know how to do is to buil a hamlet. Can you help me pls.
The easiest way to make a hamlet is to fold brown or grey construction paper into little boxes to resemble small houses. Houses from a Monopoly game would also work. You could draw the streets with s marker.
Thanks, I appreciate your help, If I have another question or problem I will tell you.
You're very welcome. Good luck with your project.
