    perimeter lesson

    Do you have geoboards at your school? I have a class set and use them to introduce perimeter. AFter I give them the definition and tell them that one peg to another in one unit, I model a shape on the board for them to copy. They count the units to find the perimeter. Then when they get the hang of it, I tell them to make a shape with a given perimeter and they hold up their boards to show me. They love using the boards. I also do a similar when I teach area. I hope this helps. Good luck!
