Sir Cumference and the Isle of Immeter Unit Study Lessons

Here are a few of the lessons you will find in this Sir Cumference and the Isle of Immeter unit study:

Perimeter
Perimeter is the length around any shape. In the game Inners and Edges, the edges were the perimeter. You find perimeter of a straight-sided shape by adding up the length of each side. To remember what perimeter is just think of it as measuring the “rim.” The word rim is in the word perimeter.

Area
Area is the amount of space inside a shape. In the game Inners and Edges, the inners referred to the area. You can find the area of a rectangle by multiplying its length and its width.

Area of a Circle
The instructions for finding the area of a circle are on page 17. There is also more information on page 32. Basically the area of a circle can be found without pi by multiplying ½ the circumference to the radius. (This lesson includes an activity and diagrams, too.)
