NCTM Principles and Standards implemented:

➢    develop, analyze, and explain methods for solving problems involving proportions such as scaling and finding             equivalent ratios
➢    understand relationships among the angles, side lengths, perimeters, areas, and volumes of similar objects
➢    use coordinate geometry to represent and examine the properties of geometric shapes
➢    use coordinate geometry to examine special geometric shapes, such as regular polygons or those with pairs of                 parallel or perpendicular side
➢    describe sizes, positions, and orientations of shapes under informal transformations such as flips, turns, slides, and         scaling
➢    draw geometric objects with specified properties, such as side lengths or angle measures
➢    recognize and apply geometric ideas and relationships in areas outside the mathematics classroom, such as art,             science, and everyday life
➢    understand both metric and customary systems of measurement
➢    understand relationships among units and convert from one unit to another within the same system
➢    understand, select, and use units of appropriate size and type to measure angles, perimeter, area, surface area, and         volume
➢    select and apply techniques and tools to accurately find length, area, volume, and angle measures to appropriate             levels of precision
➢    develop and use formulas to determine the circumference of circles and the area of triangles, parallelograms,                 trapezoids, and circles and develop strategies to find the area of more-complex shapes
➢    solve problems involving scale factors, using ratio and proportion
