We are glad to start a new year in 3rd grade.

As we start the year in math, we are reviewing place value and rounding to the nearest 10 and 100.

Rounding Rap:

Find the place value and underline the number,

Move to the right and circle, get it?

0 to 4 underlined stays the same,

5 to 9 add 1 is the game.

Now, flex your muscles like a hero,

Digits to the right turn to zero.

All the other numbers remain the same,

Yo, you're a winner in the rounding game!

We will, we will round you!

We are going into addition and the properties of addition:

**Standard form**- the number itself (235)**Expanded form -**the value of each digit added together (200 + 30 + 5)**Word form -**The number written in words (two hundred thirty-five)**Model form -**The number drawn out in hundreds tens and ones.Rounding Rap:

We are going into addition and the properties of addition:

**Commutative Property of Addition**(order property) It doesn't matter what order you add two numbers, the sum will be the same. ex. 2+3=3+2**Associative Property of Addition**(Grouping Property) It doesn't matter in what order you add numbers, the sum will be the same. ex. (2+3)+4=2+(3+4)**Identity Property of Addition -**zero plus any number is that number. ex. 0+3=3
