# Math

## Welcome to 5th Grade Math In the Fifth Grade Mathematics course students review and advance in general concepts: whole numbers, place values from millions to thousandths, graphing, decimals, fractions, measurement, and geometry. The course gives an introduction of algebraic concepts and further development of variables, averages, and order of operations. Real-world applications and problem-solving logic are used to build math confidence and provide an enjoyable learning environment. Numerous learning manipulatives and outside resources are used.

Biblical Concepts for Math:

• Man’s God –given dominion
• Man’s use of God’s resources
• Man’s responsibility to glorify God
• God’s salvation through Christ

• Christians as dependable workers
• Man’s use of wisdom to serve his fellow man
• Man’s demonstration of God’s love
• We live in an intelligently designed and ordered world

Chapter 1: Number Sense Vocabulary & Examples

Standard Form (expressing a numerical value with digits) = 329,675,187

Word Form (expressing a numerical value by using it’s word name) = three hundred twenty-nine million, six hundred seventy-five thousand, one hundred eighty-seven

Expanded Form (expressing a numerical value by expanding it to show the value of each digit) = 300,000,000 + 20,000,000 + 9,000,000 + 600,000 + 70,000 + 5,000 + 100 + 80 + 7

Expanded Form with Multiplication (expressing a numerical value by expanding it to show the value of each digit) = (3 x 100,000,000) + (2 x 10,000,000) + (9 x 1,000,000) + (6 x 100,000) + (7 x 10,000) + (5 x 1,000) + (1 x 100) + (8 x 10) + (7 x 1)

Decimal (a number that contains one or more digits to the right of the Ones place) = 4.358

Decimal point (separates the whole number from the decimal fraction) A decimal says, “AND”

Decimal Standard Form (expressing a numerical value with digits) = 4.358

Decimal to Fraction Form 4.358 = 4 358/1000

Decimal in Expanded Form (expressing a numerical value by expanding it to show the value of each digit) = 4 + 0.3 + 0.05 + 0.008

Equivalent Decimals (Have different names, but their value is the same. Zeroes placed to the right of the last digit in a decimal do not change the value) 1 = 1.0, 0.5 = 0.50, 3.01 = 3.010

Rounding Decimals (Find the rounding place. Check the digit to the right.) 12.46 rounds to 12.5, 12.43 rounds to 12.4

Integer (any whole number (not a fractional number) that can be positive, negative, or zero) Negative numbers decrease in value as you move to the left from zero, Positive numbers increase in value as you move to the right from zero.

Roman Numerals (based on symbols) I = 1, V = 5, X = 10, L = 50, C = 100

### Chapter 2: Addition & Subtraction Objectives

1. Adding & Subtracting Decimals
2. Properties of Addition & Subtraction
3. Adding & Subtracting Whole Numbers
4. Adding & Subtracting Decimals

Chapter 2: Addition & Subtraction Vocabulary & Examples

Commutative Property of Addition – The order of addends can be changed without changing the sum.

8 + 7 = 7 + 8

a + b = b + a

Associative Property of Addition – The grouping of addends, can be changed without changing the sum.

(3 + 5) + 4 = 3 + (5 + 4)

(a + b) + c = a + (b + c)

Identity Property of Addition – When 0 is added to an addend, the sum is the other addend.

7 + 0 = 7

a + 0 = a

Zero Principle of Subtraction – When 0 is subtracted from a number, the answer is that number.

6 – 0 = 6

a – 0 = a

Compensation – Allows you to adjust numbers so you can solve problems mentally.
