2d - Explain what a point (x, y) on the graph of a proportional relationship means in terms of the situation, with special attention to the points (0,0) and (l,r) where r is the unit rate.

6 - Manipulate complex fractions

7 - Factor and expand linear expressions

12 - 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.

13 - Describe the two-dimensional figures that result from slicing three-dimensional figures, as in plane sections of right rectangular prisms and right rectangular pyramids.

14 - Know the formulas for the area and circumference of a circle....give an informal derivation of the relationship between the circumference and area of a circle.

15 - Use facts about supplementary, complementary, vertical, and adjacent angles in a multistep problem to write and solve simple equations for an unknown angle in a figure.

16 - Solve real-world and mathematical problems involving...volume and surface area...

17 - 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.

18 - ....Generate multiple samples (or simulated samples) of the same size to gauge the variation in estimates or predictions.

19 - Informally assess the degree of visual overlap of two numerical data distributions with similar variabilities, measuring the difference between the centers by expressing it as a multiple of a measure of variability.

20 - Use measures of center (//not new//) and measures of variability (//range, interquartile range, mean absolute deviation, and standard deviation)// for numerical data from random samples to draw informal comparative inferences about two populations.

23 - Develop a probability model and use it to find probabilities of events. Compare probabilities from a model to observed frequencies; if the agreement is not good, explain possible sources of the discrepancy.

24 - Design and use a simulation to generate frequencies for compound events.
