Day 1

Bell Work You have ten minutes to complete the provided quick quiz.

Vocabulary _________ ___________ ____________ _____________ ___________ A mathematical sentence indicating two quantities are not equal. The distance between a number and 0 on a number line. Negative Integer- Inequality - Rational Number - Absolute Value- Positive Integer- Number Line - Any whole number greater than 0. They can be written with or without the + sign and appear to the right or above the 0. Any whole number less than 0. They are written with a – sign and appear to the left or below 0. any number that can be written as a fraction. a line on which numbers are marked at intervals, used to illustrate simple numerical operations. Integer - Is a whole number that can be greater than or less than zero.

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 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?

Integer - Is a whole number that can be greater than or less than zero.

I Can…. Identify integers representing real world situations.

+ and - Integers Essential 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.Scoring 8 pts in basketball. 8.A 2 yd. penalty. 9.A drop of 6 points in the stock market. 10. Winning $20 from the blood drive. 11.Selling $500 during the fundraising event. 12.Paying $5.00 to get into the football game. 13.A $30.00 dinner bill. 14.Finding $10 on the ground. 15.Missing 2 questions on this quiz.

Integer - Is a whole number that can be greater than or less than zero.

I Can…. 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:
