That Area is So Regular
Students explore the concept of area. In this area instructional activity, students determine the area of regular polygons on their Ti-Nspire. Students find the area of triangles, pentagons, hexagons, and heptagons. Students use trigonometric relationships to find the area of the regular polygons.

Finding the Area of Regular Polygons
Students analyze relationship between the increase in polygons sides and a circle. In this geometry activity, students relate the size of the central angle of a polygon, to a circle. They compare the formula for the area of a polygon and a circle.

Shapes and Their Insides
Learners follow a series of instructions for drawing and coloring different shapes in order to learn the difference between the perimeter and area of a polygon. Then they are asked to find the perimeter and area of a 3x4 rectangular array, while explaining in their own words what part of the shape they measured for each.
