Learning Progressions
Learning Progressions
A powerful organizing principle of the Next Generation West Virginia State Standards is that of learning progressions, where an idea is reinforced over grade levels to build depth of understanding.
Standards for Mathematical Content: Learning Progressions
“the development of these Standards began with research-based learning progressions detailing what is known today about how students’ mathematical knowledge, skill, and understanding develop over time.”
-CCSS Mathematics, p. 4
WV’s high school pathway allows for progressions to be developed that relate to important ideas in high school mathematics.
For example: Linear, Quadratic and Exponential Models
Math I linear and exponential functions,
Math II extending the ideas to quadratic functions
Math III incorporating logarithms.
In contrast, the alternate track squeezes quadratic functions into Algebra I and has a year hiatus from algebraic modeling during the Geometry course.
Grade 8• M.8.F.2 Compare properties of two functions each
represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change.
Math I
M.1HS.LER.7 For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity. (Focus on linear and exponential functions.)
Math II
M.2HS.QFM.1 For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the function is increasing, decreasing, positive or negative; relative maximums and minimums; symmetries; end behavior; and periodicity.
Pythagorean Theorem: Grade 8
• M.8.G.6 Explain a proof of the Pythagorean Theorem and its converse.
• M.8.G.7 Apply the Pythagorean Theorem to determine unknown side lengths in right triangles in real-world and mathematical problems in two and three dimensions.
• M.8.G.8 Apply the Pythagorean Theorem to find the distance between two points in a coordinate system.
Pythagorean Theorem: Math I
• M.1HS.CAG.3 Use coordinates to compute perimeters of polygons and areas of triangles and rectangles, e.g., using the distance formula. (Provides practice with the distance formula and its connection with the Pythagorean theorem.)
Pythagorean Theorem: Math II
• M.2HS.SPT.13 Prove the Pythagorean identity sin2 (θ) + cos2 (θ) = 1 and use it to find sin (θ), cos (θ), or tan (θ), given sin (θ), cos (θ), or tan (θ), and the quadrant of the angle. In this course, limit θ to angles between 0 and 90 degrees. Connect with the Pythagorean theorem and the distance formula. Extension of trigonometric functions to other angles through the unit circle is included in Mathematics III.
Message from NCTM President
by NCTM President J. Michael Shaughnessy
NCTM Summing Up, March 2011
In my view, the “layer cake” approach to high school mathematics that currently dominates so many secondary school mathematics programs—built on course sequences such as Algebra I, Geometry, Algebra II, or Algebra I, Algebra II, Geometry—is an outmoded approach in a 21st-century educational system.
Special High School Challenges
• Deeply entrenched practices tied to particular course names
• New content and perspectives
• Beliefs in teachers’ content expertise– Hard to get the conversations started
