I Can….

I can find the percent of a number.

Finding the Percent of a Number

Essential Understanding:To find the percent of a number, write the percent

as a decimal, then multiply the decimal and given number.Remember “of” is sometimes a clue word for multiplication.

Examples: 1. What is 40% of 60?

2. Find 25% of 120.

3. Determine 33% of $690.

I Can….

solve problems involving finding the whole, when given a part and the percent

Finding the whole given the part and percent.

Essential Understanding:To find the whole, when given the part and percent, you simply change the percent to a decimal and divide the "part" by the percent.

Examples:10 is 20% of what number?300 is 75% of what number?60 is 80% of what number?

Identify integers representing real world

situations.

+ and - IntegersEssential Understanding:• Positive Integers-

a) Are whole numbers greater than zero.

b) Are identified by a + sign or no sign at all.

c) Represent changes that result in an increase or gain.

Example:

• Negative Integers –

a) Are whole numbers less than zero.

b) Are identified by a – sign.

c) Represent changes that results in a decrease or loss.

Example:

• Zero is neither positive nor negative

Real World Representations

1. An increase of 7 degrees.2. A submarine 200 ft. below sea level.3. Making $300 at work.4. Spending $100 on shoes.5. Borrowing $1.25 from a friend.6. A plane 17,000 ft. in the air.7.

Locate and graph positive and negative

integers.

Locating Integers on a Number Line

Essential Understanding:• On a horizontal number line, integers are ordered from least to greatest. • So, the negative integers are to the left of zero and the positive integers

are to the right of zero. • Therefore, the farther left an integer is, on a number line, the smaller it is. • Think “left is less”

Example:

• On a vertical number line, integers are ordered from greatest to least. • So, the positive integers are above the zero and the negative integers are

below the zero. • Therefore, the lower an integers is, on a number line, the smaller it is. • Think of thermometers and temperatures “below zero”

Example:

I Can….

Determine absolute value and identify

opposites.

Absolute ValueEssential Understanding:• The absolute value of a number is its distance from zero.Model:

• The absolute value of a number is written like this

Examples:

• The absolute value of are the same because they are both 6 places from zero.

Model:

• Numbers that have the same absolute value are called opposites. Therefore, 7 and -7 are opposites.
