This document discusses strategies for differentiated instruction in mathematics. It defines differentiation as modifying tasks to fit students' ability levels, interests, and learning styles. The goals are to provide engaging math activities for all students and define several differentiation strategies with examples aligned to Common Core standards. Teachers will work in groups to create mathematical tasks with at least two modifications to differentiate instruction and consider strategies for differentiating assessment.
The concept of teaching is the fundamental study of student's cognitive action. In this paper a Trapezoidal Fuzzy Assessment model (TFAM) is developed for teaching assessment. The TFAM is a new variation of a special form, which is used in Fuzzy mathematics centre of gravity(COG) defuzzification technique. The TFAM's new idea is the replacement of the rectangles appearing in the graph of the COG method by isosceles trapezoids sharing common parts, thus covering the ambiguous cases of teachers' scores being at the limits between two successive grades (e.g between A and B). A classroom application is also presented in which the outcomes of the COG and TFAM methods are compared with those of other traditional assessment methods (calculation of means and GPA index) and explanations are provided for the differences appeared among these outcomes .

In high schools of Viet Nam, teaching calculus includes the knowledge of the real function with a real variable. A mathematics educator in France, Artigue (1996) has shown that the methods and approximate techniques are the centers of the major problems (including number approximation and function approximation...) in calculus. However, in teaching mathematics in Vietnam, the problems of approximation almost do not appear. With the task of training mathematics teachers in high schools under the new orientations, we present a part of our research with the goal of improving the contents and methods of teacher training

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. What is differentiation?
• Modifying learning tasks to better fit the ability levels,
interests, and learning styles of all students.
• Providing high-quality, engaging, and challenging
mathematics activities for all students.
3. Goals for this Session
• Define differentiation
• Examine several differentiation strategies with
examples aligned to the CCSS for Mathematics
• Create a mathematical task in grade level groups with
at least 2 modifications to differentiate instruction
• Examine strategies for differentiating assessment and
tracking student growth.
• This presentation can be accessed online at www.***
5. Grade 1-OA- Operations
and Algebraic Thinking
• 1 - Use addition and subtraction within 20 to solve word
problems involving situations of adding to, taking from,
putting together, taking apart, and comparing, with
unknowns in all positions, e.g., by using objects,
drawings, and equations with a symbol for the unknown
number to represent the problem.
• 4 - Understand subtraction as an unknown-addend
problem. For example, subtract 10 – 8 by finding the
number that makes 10 when added to 8.
10. Grades 3-5 Geometry
• 3-G-1- Understand that shapes in different categories (e.g., rhombuses,
rectangles, and others) may share attributes (e.g., having four sides), and
that the shared attributes can define a larger category (e.g.,
quadrilaterals). Recognize rhombuses, rectangles, and squares as
examples of quadrilaterals, and draw examples of quadrilaterals that do
not belong to any of these subcategories.
• 4-G-2 - Classify two-dimensional figures based on the presence or
absence of parallel or perpendicular lines, or the presence or absence of
angles of a specified size. Recognize right triangles as a category, and
identify right triangles.
• 5-G-3 - Understand that attributes belonging to a category of two-
dimensional figures also belong to all subcategories of that category. For
example, all rectangles have four right angles and squares are rectangles,
so all squares have four right angles.
16. Grade 5NF 3 - Number and
Operations - Fractions
• Interpret a fraction as division of the numerator by
the denominator (a/b = a ÷ b). Solve word problems
involving division of whole numbers leading to
answers in the form of fractions or mixed numbers,
e.g., by using visual fraction models or equations to
represent the problem. For example, interpret 3/4 as
the result of dividing 3 by 4, noting that 3/4
multiplied by 4 equals 3, and that when 3 wholes are
shared equally among 4 people each person has a
share of size 3/4.
24. HS-A-SSE-2-3-Seeing
Structure in Expressions
• 2. Use the structure of an expression to identify ways
to rewrite it. For example, see x4 – y4 as (x2)2 – (y2)2,
thus recognizing it as a difference of squares that can
be factored as (x2 – y2)(x2 + y2).
• 3. Choose and produce an equivalent form of an
expression to reveal and explain properties of the
quantity represented by the expression.
• a. Factor a quadratic expression to reveal the zeros of
the function it defines.
27. HS - A-CED-1 - Creating
Expressions
• Create equations and inequalities in one variable and
use them to solve problems. Include equations arising
from linear and quadratic functions, and simple
rational and exponential functions.

29. 5-MD-2 Measurement and Data - Make a line plot to display a data
set of measurements in fractions of a unit (1/2, 1/4, 1/8). Use
operations on fractions for this grade to solve problems involving
information presented in line plots. For example, given different
measurements of liquid in identical beakers, find the amount of
liquid each beaker would contain if the total amount in all the
beakers were redistributed equally.
30. 6-SP-5 - Statistics and
Probability
• Summarize numerical data sets in relation to their context, such as
by:
• c - Giving quantitative measures of center (median and/or
mean) and variability (interquartile range and/or mean absolute
deviation), as well as describing any overall pattern and any
striking deviations from the overall pattern with reference to the
context in which the data were gathered.
• d - Relating the choice of measures of center and variability to
the shape of the data distribution and the context in which the data
were gathered.
31.
32. Your Turn
• Each group will choose one of two standards. If your group
finishes early, you may either think about other modifications
or consider the other standard.
• Design an engaging task for students to complete to help them
develop or assess the level of proficiency in the standard
• Create at least 2 modifications of the task to differentiate
instruction. You might differentiate for ability levels, learning
styles, interests, or problem solving strategy. Consider these
questions when designing your task.
33. Grades K-2
• 2-NBT-5 - Fluently add and subtract within 100 using
strategies based on place value, properties of operations,
and/or the relationship between addition and subtraction.
• 1-MD-2 - Express the length of an object as a whole number
of length units, by laying multiple copies of a shorter object
(the length unit) end to end; understand that the length
measurement of an object is the number of same-size length
units that span it with no gaps or overlaps. Limit to contexts
where the object being measured is spanned by a whole
number of length units with no gaps or overlaps
34. Grades 3-5
• 4-NF-2 - Compare two fractions with different numerators and different
denominators, e.g., by creating common denominators or numerators, or
by comparing to a benchmark fraction such as 1/2. Recognize that
comparisons are valid only when the two fractions refer to the same whole.
Record the results of comparisons with symbols >, =, or <, and justify the
conclusions, e.g., by using a visual fraction model.
• 5-MD-3 - Recognize volume as an attribute of solid figures and
understand concepts of volume measurement.
• - A cube with side length 1 unit, called a “unit cube,” is said to have “one
cubic unit” of volume, and can be used to measure volume.
• - A solid figure which can be packed without gaps or overlaps using n
unit cubes is said to have a volume of n cubic units.
35. Grades 6-8
• 6-RP-3 - Use ratio and rate reasoning to solve real-world and mathematical problems,
e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line
diagrams, or equations.
• b - Solve unit rate problems including those involving unit pricing and constant
speed. For example, if it took 7 hours to mow 4 lawns, then at that rate, how many lawns
could be mowed in 35 hours? At what rate were lawns being mowed?
• c - Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means
30/100 times the quantity); solve problems involving finding the whole, given a part and
the percent.
• 8-NS-2 - Use rational approximations of irrational numbers to compare the size of
irrational numbers, locate them approximately on a number line diagram, and estimate
the value of expressions (e.g., π^2). For example, by truncating the decimal expansion of
√2, show that √2 is between 1 and 2, then between 1.4 and 1.5, and explain how to
continue on to get better approximations.
36. High School
• F-BF3- Building Functions- Identify the effect on the graph of
replacing f(x) by f(x) + k, k f(x), f(kx), and f(x + k) for specific
values of k (both positive and negative); find the value of k given
the graphs. Experiment with cases and illustrate an explanation
of the effects on the graph using technology. Include recognizing
even and odd functions from their graphs and algebraic
expressions for them.
• G-SRT-7 - Similarity, Right Triangles, and Trigonometry-
Explain and use the relationship between the sine and cosine of
complementary angles

43. Sample Chart to Record Student Progress
Toward Meeting the Standard
44. Other Examples of Activities
Grade 6-EE-2 Expressions and
Equations
• c - Evaluate expressions at specific values of their
variables. Include expressions that arise from
formulas used in real-world problems. Perform
arithmetic operations, including those involving
whole-number exponents, in the conventional order
when there are no parentheses to specify a particular
order (Order of Operations). For example, use the
formulas V = s3 and A = 6 s2 to find the volume and
surface area of a cube with sides of length s = 1/2.
48. 1-OA-6 Operations and Algebraic
Thinking
• Add and subtract within 20, demonstrating fluency for
addition and subtraction within 10. Use strategies such
as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 +
4 = 14); decomposing a number leading to a ten (e.g., 13
– 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship
between addition and subtraction (e.g., knowing that 8 +
4 = 12, one knows 12 – 8 = 4); and creating equivalent
but easier or known sums (e.g., adding 6 + 7 by creating
the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
