### Lesson 8: Shapes with the Same Perimeter

Goal

Draw different shapes for a given perimeter.

Instructions for Use

Cyberchase Airlines Builder asks you to make different shapes using the same perimeter. The first level of difficulty is most appropriate for you.

Click “Instructions” to read how to play, click “Next” after reading, then click “Play Game” to begin. Click “OK,” and then drag lines from the top right corner of the screen into the blue grid area to make a closed shape. To rotate a piece, click the piece so that it turns red, then click “Rotate Piece.” Pieces can be moved around on the grid as desired. When a shape is complete and all of the pieces have been used, click “Done” and then “Launch Ship!” Click “OK” to continue to make a different shape with the same perimeter (number of pieces). For help, click “Shapes You’ve Made” to see what you’ve already made and “Hint” for ideas of what shapes to make. When the first level is complete, click “OK” to continue to the next level.
