* Work cooperatively in a group

SUBJECT MATTER:

Finding the Area of Parallelogram

TIME FRAME:

• 2 Days

• VALUES:

• cooperation

• INTRODUCTION

Parallelogram is a quadrilateral with 2 pairs of parallel sides but no right angles.

Area is the number of square units in a plane. It may be in square centimeters or square meters.
