REASONING AND EXPLAINING2. Reason abstractly and quantitatively3. Construct viable arguments and

critique the reasoning of others

MODELING AND USING TOOLS4. Model with mathematics5. Use appropriate tools strategically

SEEING STRUCTURE AND GENERALIZING7. Look for and make use of structure8. Look for and express regularity in

repeated reasoning

Reflection

How are these practices similar to what you are already doing when you teach?

How are they different?

What concerns do you have with regards to the Standards for Mathematical Practice?

Standards for Mathematical Content


Are a balanced combination of procedure and understanding.

Stress conceptual understanding of key concepts and ideas


Continually return to organizing structures to structure ideas place value properties of operations

These supply the basis for procedures and algorithms for base 10 and lead into procedures for fractions and algebra

“Understand”

means that students can… Explain the concept with mathematical

reasoning, including Concrete illustrations Mathematical representations Example applications

Organization K-8

Domains Larger groups of related standards.

Standards from different domains may be closely related.

A Daily Math Program

5 Big Ideas

1. From Kindergarten on, help children develop flexible ways of thinking about numbers by having them “break apart” numbers in multiple ways

5 Big Ideas

2. From their earliest days in school, children should regularly solve addition, subtraction, multiplication, and division problems.

5 Big Ideas

3. Problem solving of all types should be a central focus of instruction.

5 Big Ideas

4. Develop number sense and computational strategies by building on children’s ideas and insights.

5 Big Ideas

5. Teach place value and multi-digit computation throughout the year rather than as “chapters”.

Number Sense

What is “number sense”?

The ability to determine the number of objects in a small collection, to count, and to perform simple addition and subtraction, without instruction.

Visualize Numbers

I am going to show you a slide for a few seconds

Record the number of dots in Box A and in Box B

READY?

Box A Box B

Record your answers

On a scale of 1-5, how confident are you that your answer is correct?

SUBITIZING

Ability to recognize the number of objects in a collection, without counting

When the number exceeds this ability, counting becomes necessary

Box A Box B

Perceptual Subitizing

Maximum of 5 objects

Helps children Separate collections of objects into single

units Connect each unit with only one number

word Develops the process of counting

Subitizing

Conceptual Subitizing

Allows children to know the number of a collection by recognizing a familiar pattern or arrangement

Helps young children develop skills needed for counting

Helps develop sense of number and quantity

Children who cannot conceptually subitize will have problems learning basic arithmetic processes

Subitizing

Practicing Subitizing

Use cards or objects with dot patterns Groups should stand alone Simple forms like circles or squares Emphasize regular arrangements that

include symmetry as well as random arrangements

Have strong contrast with background

Avoid elaborate manipulatives

CCSS - NBTExtend the counting sequence.1. Count to 120, starting at any number

less than 120. In this range, read and write numerals and represent a number of objects with a written numeral.

CCSS - NBTUnderstand place value.2. Understand that the two digits of a

two-digit number represent amounts of tens and ones. Understand the following as special cases:a) 10 can be thought of as a bundle of

ten ones — called a “ten.”b) The numbers from 11 to 19 are

composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones.

CCSS - NBTUnderstand place value.

c) The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight, or nine tens (and 0 ones).

3. Compare two two-digit numbers based on meanings of the tens and ones digits, recording the results of comparisons with the symbols >, =, and <.

CCSS – NBT

Use place value understanding and properties of operations to add and subtract.5. Given a two-digit number, mentally

find 10 more or 10 less than the number, without having to count; explain the reasoning used.

Math Talk

Students do better in classrooms where teachers use numbers as regular part of day

Reflection

Where, in the course of a normal day, can you find places to talk about numbers OUTSIDE OF MATH TIME?

Where do numbers occur in the everyday lives of your students?

Shapes Time Money

Daily Math, continuedGeometry Plane Shapes: Rectangles, Squares,

Triangles, Trapezoids, Half-Circles, Quarter-Circles

Solids: Cubes, Right Rectangular Prisms, Right Circular Cones, Right Circular Cylinders

Be able to identify critical attributes Continue to review shapes from K

CCSS – Geometry

Reason with shapes and their attributes.1. Distinguish between defining

attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.

Daily Math, continuedGraphs and Data At least once a month – related to

things about the kids Graphs represent real people and real

data Ask a wide variety of problems related

to the graph including “What would happen if….” questions

CCSS – MD Represent and interpret data.4. Organize, represent, and interpret

data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.

Daily Math, continuedTime Morning, afternoon, evening, am, pm Order of events To the nearest 5 minutes (depends on

grade level)

CCSS – MD Tell and write time.3. Tell and write time in hours and half-

hours using analog and digital clocks.

Daily Math, continuedMoney Names of Coin Values of Coin

Addition and Subtraction Facts

CCSS – OA Understand and apply properties of operations and the relationship between addition and subtraction.3. Apply properties of operations as

strategies to add and subtract.3 Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)

CCSS – OA Understand and apply properties of operations and the relationship between addition and subtraction.4. Understand subtraction as an

unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8.

CCSS – OA Add and subtract within 20.5. Relate counting to addition and

subtraction (e.g., by counting on 2 to add 2).

6. 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).

CCSS – OA Work with addition and subtraction equations.7. Understand the meaning of the equal

sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 – 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.

CCSS – OA 8. Determine the unknown whole number

in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = – 3, 6 + 6 = .

Teaching for Understanding

Telling students a procedure for solving computation problems and having them practice repeatedly

rarely results in fluency

Because we rarely talk about how and why the procedure works.

Teaching for Understanding

Students do need to learn procedures for solving computation problems

But emphasis (at earliest possible age) should be on why they are performing certain procedure

Research

Students who learn rules before they learn concepts tend to score significantly lower than do students who learn concepts first

Initial rote learning of a concept can create interference to later meaningful learning
