District School Curriculum Teaching Students


A Long Overdue Shifting of the Foundation

For as long as most of us can remember, the K-12 mathematics program in the U.S. has been aptly characterized in many rather uncomplimentary ways: underperforming, incoherent, fragmented, poorly aligned, narrow in focus, skill-based, and, of course, “a mile wide and an inch deep.”

---Steve Leinwand, Principal Research Analyst American Institutes for Research in Washington, D.C


But hope and change have arrived!

Like the long awaited cavalry, the new Common Core State Standards for Mathematics (CCSS) presents us a once in a lifetime opportunity to rescue ourselves and our students from the myriad curriculum problems we’ve faced for years.

---Steve Leinwand, Principal Research Analyst American Institutes for Research in Washington, D.C

Make no mistake,

for K-12 math in the

United States, this IS a brave

new world.

Digging in…

Begin to unearth some discoveries:


2NBT9. Explain why addition and subtraction strategies work, using place value and the properties of operations.

3OA3. Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.

4NF2. 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.

Operations and Algebraic Thinking Dr. Jason Zimba

Professor of Physics and MathematicsBennington College, Vermont

Lead Writer, Common Core Standards for Mathematics


The number strand “has often been a single strand in elementary school, but in CCSS it is three domains.”

Operations & Algebraic Thinking (OA)

‘“Addition, subtraction, multiplication, & division have meanings, mathematical properties, and uses that transcend the particular sorts of objects that one is operating on, whether those be multi-digit numbers or fractions or variables or variables expressions.”


Properties of the Operations

ContextualSituations

Meanings of the Operations

The foundation for algebra!


72 – 29 = ?

Mental Math Solve in your head. No pencil or paper!

24 x 25 = ?

Nor calculators, cell phones computers, or iPads or ....


72 – 29 = ? 24 x 25 = ?

Turn and share your reasoning.

Discuss how you: “Decomposed and composed the quantities.”

(a.k.a. properties of the operations)


24 x 25 = ?

I thought 24 x 100 = 2400,

and 2400 ÷ 4 = 600.

I thought 25 x 25 = 625 and then I subtracted 25. 625 – 25 = 600.

I figured that there are 4 twenty-fives in 100,

and there are 6 fours in 24, so 100 x 6 = 600.


24 x 25 = ?

25 x 4 = 100, 6 x 100 = 600, 600 + 100 = 700.

Well,10 x 25 = 250, 2(10 x 25) = 500,500 x 4 = 2000.

“I would try to multiply in my head, but I can't do that.”


The properties of operations.

Associative property of addition (a + b) + c = a + (b + c)

Commutative property of addition a + b = b + a

Additive identity property of 0 a + 0 = 0 + a = a

Existence of additive inverses For every a there exists –a so that a + (–a) = (–a) + a = 0

Associative property of multiplication (a × b) × c = a × (b × c)

Commutative property of multiplication

a × b = b × a

Multiplicative identity property of 1 a × 1 = 1 × a = a

Existence of multiplicative inverses For every a ≠ 0 there exists 1/a so that a × 1/a = 1/a × a = 1

Distributive property of multiplication over addition

a × (b + c) = a × b + a × c

Not just learning them,

but learning to use them.


And in the domain of Operations and Algebraic Thinking, it is those meanings, properties, and uses which are the focus; and it is those meanings, properties, and uses that will remain when students begin doing algebra in middle grades [and beyond].

--Jason Zimba


In Grades K-8, how many standards reference “properties of the operations”?

28 standards

Grade 1: OA, NBTGrade 2: NBTGrade 3: OA, NBTGrade 4: NBT, NFGrade 5: NBTGrade 6: NS, EEGrade 7: NS, EEGrade 8: NS

12% of K-8 standards


Using properties of operations 1OA3. Apply properties of operations as strategies to

add and subtract.

3OA5. Apply properties of operations as strategies to multiply and divide.

4NBT5. Multiply two two-digit numbers using strategies based on place value and the properties of operations.

Develop and use strategies

based on properties of the operations


CCSS Glossary

Computation strategy Purposeful manipulations that may be chosen for specific problems, may not have a fixed order, and may be aimed at converting one problem into another.

Computation algorithm A set of predefined steps applicable to a class of problems that gives the correct result in every case when the steps are carried out correctly.

Standard 1OA6: “Basic Facts”

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).


Standard 3OA5: Basic Facts

Apply properties of operations as strategies to multiply and divide. Examples:

If 6 × 4 = 24 is known, then 4 × 6 = 24 is also known. (Commutative property of multiplication.)

3 × 5 × 2 can be found by 3 × 5 = 15, then 15 × 2 = 30, or by 5 × 2 = 10, then 3 × 10 = 30. (Associative property of multiplication.)

Knowing that 8 × 5 = 40 and 8 × 2 = 16, one can find 8 × 7 as 8 × (5 + 2) = (8 × 5) + (8 × 2) = 40 + 16 = 56. (Distributive property.)

Turn around facts

Double a known fact

Use a helping fact


In Grades K-8, how many standards reference using “algorithms”?

5 standards

Grade 3: NBT2

Grade 4: NBT4

Grade 5: NBT5

Grade 6: NS2, NS3

2% of K-8 standards


Algorithms

Grade 3 “use strategies and algorithms” to add and subtract within 1000. (Footnote: A range of algorithms may be used.) (3NBT2)

Grade 4 “use the standard algorithm” to add and subtract multi-digit whole numbers. (4NBT4)

Grade 5 “use the standard algorithm” to multiply multi-digit whole numbers. (5NBT4)

Grade 6 “use the standard algorithm” to divide multi-digit numbers and to divide multi-digit decimals. (6NS2, 6NS3)


Strategies first!Develop and use strategies

for learning basic facts before any expectation of

knowing facts from memory.


Strategies first!Develop and use strategies to compute with whole numbers, fractions, decimals …. before use of standard algorithms.

Shifts in Classroom Practice


Shifts . . . ContentLess data analysis and probability in K-5

More statistics in 6-8 and lots more in HS Much more emphasis on statistical variability

Less algebraic patterns in K-5 Much more algebraic thinking in K-5 More algebra in 7-8 and functions in 8th

More geometry in K-HS Much more transformational geometry in HS.

More focus on Ratio and Proportion beginning in 6th Percents in 6-7, not in K-5


Shifts… Curriculum & Assessment

HS standards as “conceptual categories” not courses ….

supports either integrated or traditional approach or new models that synthesize both approaches.

Real-world applications, contexts, and problem solving

Strong emphasis on contexts and word problems from K-HS

Use of measurement contexts across domains, especially “linear” and “liquid” contexts

Multi-step Word Problems beginning in Grade 2

Mathematical modeling interwoven throughout HS


Shifts . . . Teaching

Using a “unit fraction” approach Understand and use unit fraction reasoning and

language and expect it of our students

Increased emphasis on visual models Number line model Area model

Strategies and sense-making before algorithms Strategies based on properties of the operations Algorithms culminate years of prior work

Discrete to

continuous quantities


And so in closing …


Focus: Unifying themes and guidance on “ways of knowing” the mathematics.

Coherence: Progressions across grades based on discipline of mathematics and on student learning.

Understanding: Deep, genuine understanding of mathematics and ability to use that knowledge in real-world situations.


Please keep digging, there are many more discoveries in the Core to unearth and we know that the work we are all doing is important for Wisconsin students, for their learning and understanding of mathematics, and for their futures.
