1. (M7) Unit-8: 2D-Figures Days 94 - 105
Common Core Standards
7.G.1 : Solve problems involving scale drawing of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale.
7.G.2: Draw (freehand, with ruler and protractor, and with technology) geometric shapes with given conditions. Focus on constructing triangles from three measures of angles or sides, noticing when the conditions determine a unique triangle, more than one triangle, or no triangle.
7.G.4: Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle.
7.G.6: Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms

After each shape/slide, give students two more of the same shape with measurements on the whiteboard and ask them to find the area and perimeter. Repeat with each slide. The purpose of this is to reinforce what you are going over in the ppt. This will help you determine if you need to spend more time on any of the figures.

3) The illustration shows the relationship between the circumference and area. If a circle is cut into wedges and laid out as shown, a parallelogram results. Half of an end wedge can be moved to the other end a rectangle results. The height of the rectangle is the same as the radius of the circle. The base length is the circumference (2∏r). The area of the rectangle (and therefore the circle) is found by the following calculations:
Arect = Base x Height
Area = ½ (2∏r) x r
Area = ∏r x r
Area = ∏r2
