these on the graph paper supplied ............ just ask.]

Lesson Plan using "geoboard".
With this task, you need to go to the activities on the right side and
choose those about perimeter.
http://matti.usu.edu/nlvm/nav/frames_asid_172_g_2_t_3.html?open=activities
On a geoboard, to find the perimeter of a
rectangle you can count the number of spaces between pins
along the path of the elastic. To find the area you
multiply the number of spaces between pins on two adjacent
sides of the rectangle.
|
The smallest rectangle you can make is
actually a square with area of 1 and perimeter of 4.
|
| See if you can find each of the following: |
| |
Find two rectangles with the same perimeter,
but different areas. |
| Can you find another pair with the same perimeter, but
different areas? |
| |
Find two rectangles with the same area, but
different perimeters. |
| How many figures (squares and
rectangles) can you create that have a perimeter equal to
their area? |
|
How many different sized squares and
rectangles can be made on the geoboard (no diagonals!). |
|
|
This Activity
when you have been told its Ok to do so.
Watch the perimeter change and work it out. Just for your information.

For
additional work, follow this plan.
Students will need:
1. We are going to use the computers to learn about
perimeter, but please do not turn your computers on or go to this page
until I ask you to. I want to show you a little about the Shape
Explorer applet first.
2. Watch the screen and see if you can understand this discussion
about how to find the perimeter for random shapes.
- Perimeter is the total length around the object. So imagine the
grid lines are equal to one step. And imagine the outside edges of
the figure are tight ropes. You want to see how many steps it will
take you to get all the way around the edge. The number of steps
would be the perimeter.
- Once we have calculated the perimeter we will put our answer in
the perimeter input box and click the check answer button. For now,
ignore the area input box.
3. Collect the
Worksheet
to Accompany the "Perimeter Explorer" Applet
now and complete it.
The
Perimeter
Explorer is here. Click on the blue writing.
