week 5

Subtraction and multiplication algorithms


https://docs.google.com/document/d/1-Gaiqi0uGc9Qw6zJZxLGtZCi6tR-KQccZKyHqwxgao4/edit



went over test and did review

Week 4

Addition algorithm's/Subtraction/ multiplication and division


https://docs.google.com/document/d/1-Gaiqi0uGc9Qw6zJZxLGtZCi6tR-KQccZKyHqwxgao4/edit

Four operations


Addition: putting together


Identity property:

A + O = A


Communitive Property (Order Property): when adding two numbers together the order doesn't matter.

a+b=b+a

3+4 = 4+3


Associative Property (Grouping): when adding numbers the grouping does not matter.

(a+b)+c= a+(b+c)


Subtraction (Take Away)

Comparison

Missing Addend

________________________________________________________________

Multiplication (Repeated Addition)

2+2+2 = 3x2


Identity: when a number is multiplied by one it will stay the same

Ax1 = A, 1x1 = 1


commutative property: when you multiply two numbers together the order doesn't matter.

A,B

AxB = BxA

3x7 = 7x3


associative property: when multiplying numbers the grouping does not matter

(a*b)xc=ax(b*c)


Zero Property

anything multiplied by zero will equal zero

Ax0 = 0

3x0 = 0


Array

How many numbers will go into a group


Distributive property

A x (B+C) = (AxB) + (AxC)

Week 3

went over homework number 2 and did mind map

went over base numbers


Base 10:

ones 10^0

tens 10^1

hundreds 10^2

thousands 10^3


Base 5

ones 5^0

fives 5^1

25s 5 ^2

125s 5^3


Base 3

ones 3^0

threes 3^1

nines 3^2

27s ^5



Week 2

Numberation systems


Base 10 or a decimal systems


Expanded notation

373

300 + 70 + 2

3x100 = 7x10 + 2x1


digits used: 0,1,2,3,4,5,6,7,8,9


Base-10/Decimal

used in schools and daily life

consistent one to ten relationship between the digits in base-10

EX: ten units make a ten, Ten tens make 100




Went over problem solving again


Understand the problem

Devise a plan (trial and error, make a table, picture, diagram)

Carry out the plan ( be patient)

Look back and reflect (Does It make sense)


Solved problems that required different combinations

Went over the handshake problem

Went over the problem with stamps

Went over the problem with basketball teams
