Announcements:
Monday, October 11th there is no school to celebrate Columbus Day.

This week we will start the Weekly Math Word Problems. A letter with details will be coming home on Tuesday. Your child's folder (it says on the front Stays Home) with the strategies and key words does not come back to school. It is to be used to assist them with the word problems.

We will be working on a unit for paragrah writing. Most of the work will be worksheets rather than the workbook.

Math Terminology:
Addition Properties:

Commutative Order Property- (COP) No matter what order the addends are in, the sum is always the same.
Ex. 4 + 5  = 9 or 5 +4 = 9

Associative Order Property- (GAP) No matter which way the addends are grouped, the sum is always the same. This property always has 3 or more addends and has parenthesis. Always add what’s in parenthesis first.
Ex. 7 + ( 2 + 1) = 10 or 2 + (7 + 1) = 10

Identity Property- Any addend plus zero is itself.
Ex. 6 + 0 = 6

Addend- The numbers you use when you add.

Sum- The answer in addition. 

ESTIMATION RULES:

1. Decide which 2 places the number is between.
Ex. 17 is between 10 and 20 
Ex. 168 is between 100 and 200

2. Look at the place value before the place you are rounding to. If that digit is 5 or higher round up. If it's 4 and lower round down.

Ex. If you're rounding to the 10's look at the 1's place. 17 would round to 20

Ex. If you're rounding to the 100's place look at the 10's place. 168 would round to 200

Ex. If you're rounding to the 1000's place look at the 100's place. 1,264 would round to 1,000

3. If you're rounding two different numbers always round both to the lowest place value. This is used when we will be estimating sums. 

Ex. 34 + 489 would be 30 + 490 = 520 In this example both places would be rounded to the tens place.

Digit- A single number

Period​- ​There are 3 periods: the ones, thousands, ten thousands. 

Place- Where a digit is in each period.

Ex. 3,987 The 9 is in the hundreds place.

Place Value- The worth of a digit in its place.

Ex. 3987 The value of the 9 is 900.

Standard Form- Regular way we write numbers everyday. 

Ex. 725

Expanded Form- This is the number written by first determining the place and then finding its value.

Ex. 700 + 20 + 5

Written Form- This is the number written in words.

Ex. Seven hundred twenty five
