Week One:
Polya's four steps to problem solving
1.) Understand the problem
2.) Devise a plan
3.) Carry out the plan
Look back (reflect)
Ask youeself what problem solving strategy are you going to use?
Guess and use check/trial and error
Draw a picture or a diagram
Act it out
Make the problem simpler
Look for the pattern
Work backwards
Make an organized list
When teaching make sure students
1.) Understand
2.) Plan
3.) Implement
Look back to check if results are reasonable

Intager Subtraction
Meanings
1.) Take Away 5-2=3
2.) Comparison
3.) Missing Add End
7-3=4
4 is the Difference
3 is the subtrahend
7 is the Minuend
Week 5:
Multiplication
Meaning: Repeated Addition
(3 x z) is 3 groups of z
Week Four:
Division
Week Four:
Week Two:
Numeration Systems
-Base-10 System
-The Value of the number depends on the place
-The numbers get bigger by 10 times (1/10) x (1/10)= (1/100)
Numbers to the right of the decimal are part of the unit
Expanded Notation
Week One:
Make sure students understand the problem by having them explain the problem in their own words or show how to complete it.
Make sure students:
1.) Understand
2.) Plan
3.) Implement
4.) Look back reasonably
Divisibility Rules
*Sum of Digits
-By 3: Sum of digits is divided by 3
*Ending
-By 2: 0,2,4,6,8
-By 5: 0,5
-By 10: 0
*Last Digits
-By 4: Last two digits are divided by 4
Number Theory
-Types of Numbers
-Divisibility
-Factors-multiples>Fraction work
Pie=3.14 not a decimal it is a irrational number
Week 11
Could use fraction form
Week 12
Percent=Per 100
They tell kids to bring the decimal point up
Week 13
% Problem Solving:
* is =
of is x
what is n
% is decimal
(8% is 0.08
Week 13
Week 14
Division:
+3x+2=+6
+6 (divided) +3=+2
+6 (divided) +2=+3
