What are we learning?:

What are we learning? Our Standard Says NBT2 Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction. Copyrighted 2012 by Elizabeth Hill

In Kid Terms:

In Kid Terms I understand and can use the properties of addition. Copyrighted 2012 by Elizabeth Hill

Let’s Take Another Look at 12:

Let’s Take Another Look at 12 0+12 1+11 2+10 3+9 4+8 5+7 6+6 7+5 8+4 9+3 10+2 11+1 0+12 Which problems go together? Why do they go together? Copyrighted 2012 by Elizabeth Hill

Let’s Play a Game:

Let’s Play a Game We need: Dice White Boards Marker Partners Roll the dice. Write the addition fact that goes with the numbers you rolled. 2+4=6 3. Write the matching fact. 4+2=6 4. Finally write it showing the Commutative Property. 2 + 4 = 4 + 2 Copyrighted 2012 by Elizabeth Hill

The Properties of Addition Properties - the rules of addition that make problems easier. 1. Commutative Property – It doesn’t matter what order you add 2 numbers. The answer is always the same. Ex: 4+3=3+4 2. Associative Property – When you add 3 or more numbers together, it doesn’t matter how you group them. The answer will be the same. Ex:(9+2)+3=9+(2+3) 3. Identity Property – When adding 0 to a number, the answer will always be that number. Ex: 7+0=7 Addend -the two numbers being added together Sum -the answer to an addition problem Copyrighted 2012 by Elizabeth Hill

Associative Property:

Associative Property When I think about the associative property, I think about the Jonas Brothers. The 3 of them are always together. When you see 2 of them together, the other is somewhere near. + + No matter which 2 you see first, you will still have the Jonas Brothers. = Copyrighted 2012 by Elizabeth Hill

Associative Property:

Associative Property (2+3)+5= 2+ 3+5 What are the numbers you should write on the other side? Where should the parentheses go to show what to associate? ( ) What 2 numbers are being associated? Copyrighted 2012 by Elizabeth Hill

Associative Property:

Associative Property (1+4)+6= 1 + 4+6 What are the numbers you should write on the other side? Where should the parentheses go to show what to associate? ( ) What 2 numbers are being associated? Copyrighted 2012 by Elizabeth Hill

Associative Property:

Associative Property 8+(9+2)= 8+9 +2 What are the numbers you should write on the other side? Where should the parentheses go to show what to associate? ( ) What 2 numbers are being associated? Copyrighted 2012 by Elizabeth Hill

Associative Property:

Associative Property 7+(4+6)= 7+4 +6 What are the numbers you should write on the other side? Where should the parentheses go to show what to associate? ( ) What 2 numbers are being associated? Copyrighted 2012 by Elizabeth Hill

Identity:

Identity Your identity is who you are. Who you are doesn’t change. You are always you. No matter how you change (clothes, hair, size), you are always you. Copyrighted 2012 by Elizabeth Hill

Identity:

Identity Peter Parker puts on a costume & becomes Spiderman. But underneath the Spidey suit, he is still Peter Parker. His identity did not change. Copyrighted 2012 by Elizabeth Hill

Identity:

Identity Miley Cyrus puts on a wig & becomes Hannah Montana. But underneath the blonde wig, she is still Miley Cyrus. Her identity did not change. Copyrighted 2012 by Elizabeth Hill

Identity Property:

Identity Property The identity property is the rule of what makes a number stay the same or keep its identity. Identity Property of Addition What number do you add to 5 to make it stay 5? 0 5+0=5 When you add 0 to 5, 5 keeps its identity. Copyrighted 2012 by Elizabeth Hill
