10th grade Academic Content Standards
These are what we will be studying this year
Number, Number Sense and Operations Standard
____ 1. Connect physical, verbal and symbolic representations of irrational numbers; e.g., construct as a hypotenuse or on a number line.
____ 2. Explain the meaning of the nth root.
____ 3. Use factorial notation and computations to represent and solve problem situations involving arrangements.
____ 4. Approximate the nth root of a given number greater than zero
between consecutive integers when n is an integer; e.g., the 4th root
of 50 is between 2 and 3.
____ 1. Explain how a small error in measurement may lead to a large error in calculated results.
____ 2. Calculate relative error.
____ 3. Explain the difference between absolute error and relative error in measurement.
____ 4. Give examples of how the same absolute error can be problematic in one situation but not in another; e.g., compare “accurate to the nearest foot” when measuring the height of a person versus when measuring the height of a mountain.
____ 5. Determine the measures of central and inscribed angles and their associated major and minor arcs.
Geometry and Spatial Sense Standard
____ 1. Formally define and explain key aspects of geometric figures,
a. interior and exterior angles of polygons;
b. segments related to triangles (median, altitude, midsegment);
c. points of concurrency related to triangles (centroid, incenter,
d. circles (radius, diameter, chord, circumference, major arc, minor
arc, sector, segment, inscribed angle).
____ 2. Recognize and explain the necessity for certain terms to remain undefined, such as point, line and plane.
____ 3. Make, test and establish the validity of conjectures about geometric properties and relationships using counterexample, inductive and deductive reasoning, and paragraph or two-column proof, including:
a. prove the Pythagorean Theorem;
b. prove theorems involving triangle similarity and congruence;
c. prove theorems involving properties of lines, angles, triangles
d. test a conjecture using basic constructions made with a compass
and straightedge or technology.
____ 4. Construct right triangles, equilateral triangles, parallelograms, trapezoids, rectangles, rhombuses, squares and kites, using compass and straightedge or dynamic geometry software.
____ 5. Construct congruent figures and similar figures using tools, such as compass, straightedge, and protractor or dynamic geometry
____ 6. Identify the reflection and rotation symmetries of two- and three dimensional figures.
____ 7. Perform reflections and rotations using compass and straightedge constructions and dynamic geometry software.
____ 8. Derive coordinate rules for translations, reflections and rotations of geometric figures in the coordinate plane.
____ 9. Show and describe the results of combinations of translations,
reflections and rotations (compositions); e.g., perform compositions
and specify the result of a composition as the outcome of a single
motion, when applicable.
____ 10. Solve problems involving chords, radii and arcs within the same circle.
Patterns, Functions and Algebra Standard
____ 1. Define function formally and with f(x) notation.
____ 2. Describe and compare characteristics of the following families of functions: square root, cubic, absolute value and basic trigonometric functions; e.g., general shape, possible number of roots, domain and range.
____ 3. Solve equations and formulas for a specified variable; e.g., express the base of a triangle in terms of the area and height.
____ 4. Use algebraic representations and functions to describe and
generalize geometric properties and relationships.
____ 5. Solve simple linear and nonlinear equations and inequalities having square roots as coefficients and solutions.
____ 6. Solve equations and inequalities having rational expressions as coefficients and solutions.
____ 7. Solve systems of linear inequalities.
____ 8. Graph the quadratic relationship that defines circles.
____ 9. Recognize and explain that the slopes of parallel lines are equal and the slopes of perpendicular lines are negative reciprocals.
____ 10. Solve real-world problems that can be modeled using linear,
quadratic, exponential or square root functions.
____ 11. Solve real-world problems that can be modeled, using systems of linear equations and inequalities.
____ 12. Describe the relationship between slope of a line through the origin and the tangent function of the angle created by the line and the positive x-axis.
Data Analysis and Probability Standard
____ 1. Describe measures of center and the range verbally, graphically and algebraically.
____ 2. Represent and analyze bivariate data using appropriate graphical displays (scatterplots, parallel box-and-whisker plots, histograms with more than one set of data, tables, charts, spreadsheets) with and without technology.
____ 3. Display bivariate data where at least one variable is categorical.
____ 4. Identify outliers on a data display; e.g., use interquartile range to identify outliers on a box-and-whisker plot.
____ 5. Provide examples and explain how a statistic may or may not be an attribute of the entire population; e.g., intentional or unintentional bias may be present.
____ 6. Interpret the relationship between two variables using multiple graphical displays and statistical measures; e.g.,scatterplots, parallel box-and-whisker plots, and measures of center and spread.
____ 7. Model problems dealing with uncertainty with area models
____ 8. Differentiate and explain the relationship between the probability of an event and the odds of an event, and compute one given the other.
