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.
