##### Description:

1. Make sense of problems and persevere in solving them. 2.Model with mathematics. 3. Use appropriate tools strategically. 4. Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. 5. Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships. 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. 7. Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Understand that random sampling tends to produce representative samples and support valid inferences. 8. Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations.
