## Math

I will try to keep this updated on what we are working on in math. If you want to work with your children in your free time, I would greatly appreciate. Simply ask your child what they are working on in math and have them explain it to you.

Something that you can always work on with your child is multiplication and division facts. We will be doing a weekly timed test of those facts for the Principals math honor roll.

Chapter 6: Fractions

Equivalent Fractions: 2/3 is equal to 4/6 and 8/12

Simplest Form: 6/8 = 3/4

Common denominators: 1/4 and 2/3 = 3/12 and 8/12

Order Fractions: (least to greatest using common denominator) 1/5 , 5/8 , 2/3

Chapter 5: Factors, Multiples, and Patterns

Factors: All the numbers that you use to make a number

Ex: Factors of 30 are: 1,2,3,5,6,10,15,30

Multiples: The product of two numbers is a multiple of each number.

Ex: Multiples of 2: 2,4,6,8,10........

Prime numbers: a whole number greater than 1 that has exactly two factors, 1 and itself.

Composite numbers: a whole numbers greater than 1 that has more than two facts.

Patterns: Continue the pattern:

5,13,21,29

Chapter 4: Division

We will be working on dividing 1, 2, 3, and 4 digit number by 1 digit numbers.

Example: 987 divided by 3 equals 329

The students will be asking themselves how many times will the divisor (3) go into the dividend (329)

The students should still be practicing their multiplication.

Chapter 2 & 3: Multiply by 1- Digit Numbers and 2- digit numbers by 2 digit numbers

The students are working on multiplication. This is a difficult chapter because most students do not know all of their basic multiplication facts. They need to know their facts in order to do 2 digit multiplication.

Examples: 3 x 8,000

The students learned an easy technique I call boxing in your zeros.

When you put a box around your zeros they temporarily disappear, so you are left with 3 x 8. That is much simpler to solve.

3 x 8 = 24

Then the students much put back those zeros!

So the answer becomes 24,000

Chapter 2 once again works with rounding.

0-4 stay the same

5-9 go up 1

Place value comes very useful during this chapter as well. The students will need to know that 19 is 1 ten and 9 ones.

The students can NEVER have to much practice with place value.

The following are two pictures:

1. Key words that the students look for when they are solving word problems. Key words let the students know what type of problem they are solving.

2. The two digit by two digit multiplication that we will be working on very soon.

Chapter 1: Place Value

The students are working on what the value of each individual number in a bigger number are.

Example: 9,6

The value of the 4 is 40 because it is in the tens spot, so it is 4 tens.

The students are working on the 3 different forms a number can be in:

Standard for: 9,647

Work form: Nine thousand six hundred forty seven

Expanded form: 9,000 + 600 +40 +7

They are also comparing numbers.

9,647 > 659

Below is a picture of a place value chart that I have in the classroom so that you can get an idea on the chart the students use to work with place value.

Rounding Numbers

Some of the students are struggling with rounding large numbers.

Example: Round to the nearest thousands place

2,467 rounds to 2,000

169,445 rounds to 169,000

Round to the digit underlined:

1

The kids remember it as: 0-4 stay the same and 5-9 go up one
