Scaling Principal for Areas and Volumes
1 Scaling Principal for Areas and Volumes
The scaling Principal for Areas and Volumes mini lesson takes students through the procedure of finding how the scale factor (ratio 0f Side-Length) is the magnitude-squared or the magnitude-cubed respectively when working with similar polygons and solids.
Inventory for Area of Polygons:
DIRECTIONS: FIND 2-OTHER STUDENTS IN YOUR CLASS WHO CAN EASILY GIVE THE area OF A RECTANGLE AND TRIANGLE. WRITE THE NAME OF THE PERSON WHOM YOU ASKED ABOUT THE AREA OF A RECTANGLE IN THE 1ST BOX AND THE NAME OF THE 2ND PERSON YOU ASKED HOW TO FIND THE AREA OF A TRIANGLE IN THE SECOND BOX.
