Math Talk

“Math is a Language” - Josiah Willard Gibbs

Protocols:

  1. Respect all idea.  Don’t make fun of others’ ideas.
  2. Raise hand when you have an idea.
  3. No side talk--write it down instead.
  4. Stay focused.
  5. Be an active listener--thinking, note taking and questioning as we talk together.

September 27th Discussion--the Language of Numbers


What words can we use to describe numbers?  How does that help us use and understand numbers in our daily life?

Words That Describe Numbers

Comic Strip Creator Teams

Definitions

Ways that word helps us to learn math and succeed in daily life?

Every number has a name

2,000,000 vs 2 vs 200

You have to understand the number’s value (how big it is).

We have to understand place value.

  • You can get cheated w/money
  • Understand the value of items

*Shel Silverstein poem

Even

Kya/Laura

It can be divided into two equal groups.

  • To divide into two groups.
  • What’s it’s connection to symmetry.
  • (E + E = E)

Odd

Liang/Shawn

It can’t be divided into two whole numbers.

  • Half of the digits make odd numbers when you’re talking about single digit numbers.
  • Add two odds and you get an even (two even groups of odd, make even) (O + O = E)
  • Add odd plus even always equals odd. (E + O = O)

Digits:  0, 1, 2, 3, 4, 5, 6, 7, 8, 9

There are only ten digits

Haeun/Aarushi

The digits are the figures the that make up all numbers to “infinity and beyond.”

  • Working with money.
  • Write all numbers.

Whole Number-Gabriella

No decimals, no fractions -- it’s the whole thing such as 1, 2, 3, …..35, 36...100

Multiples

“Buzz Lightyear Numbers”

Aidan/Kevin

It’s counting by a specific number.  The multiples of 12 are 12, 24, 36, 48. . .

Multiples go to infinity and beyond. . .

Factor

1 is a factor of all numbers.

 2 is a factor of all even numbers.

Yana/Tamira

Factors are numbers you multiply to get a product (answer in multiplication)

The factor pairs for 24 are:

1X24

2X12

3X8

4X6

Square Numbers

Jaden/Modib

Numbers that make a square when you draw an array like this 4 is a square number:

Square numbers have two factors that are the same such as 3X3 = 9, 9 is the square number.  16 is square because 4 X 4 = 16.

Prime

 2 is the only even prime #

Dravin/Marcos

It’s a number that can only be divided by one and itself or it only has one factor pair: 1 X itself.

2,3,5,7,11,13,17,19,23,29,31,37, 41, 43, 47, 51, 53, 59, 61, 67,

Composite

Alex/Dylan

They two or more factor pairs, they are the opposite of primes

Composite Numbers Less than twenty:

4: 1X4, 2X2

6: 1X6, 2X3

8: 1X8, 2X4

9: 1X9, 3X3

10: 1X10, 2X5

12: 1X12, 2X6, 3X4

14: 1X14, 2X7

15: 1X15, 3X5

16: 1X16, 2X8, 4X4

18: 1X18, 2X9, 3X6

20: 1X20, 2X10, 4X5

Zero

is a whole number, not composite or prime

one

not composite or prime

Product

Artur/Kayla

Result of Multiplying

___X___ = Product

Sum

Gabriella/Nich

Result of adding

___+___= sum

Difference

Angela/Elissa

Result of Subtracting

___-____= Difference

Quotient

Result of division

____/_____= quotient

Ascending Order

Going up in value

Consecutive Order

Number in order

Descending Order
