Comparing Integers

100

• Is the statement "-5 > 2" true or false? Explain your reasoning.

False, any positive and greater than a negative 

200

• Decide whether "-12 > -15" is true or false. Show how positions on a number line help you decide.

True, -12 is closer to 0

300

• Which is greater: -3 or -7? Write the inequality and explain in one sentence using "left" or "right" on a number line.

-3 > -7, -3 is closer to 0

Integer Operations

100

• Evaluate: It was 8 degrees at nightfall. The temperature dropped 10 degrees by midnight. What was the temperature at midnight?

-2

200

• If you add 6 and -4, what is the result? Show the sum on a number line or explain with direction.

2

300

• Subtract: −2−5. Compute the result and explain the steps.

-7, start at -2 and move to the left 5 times 

Temperatures & Elevation

100

• Represent "3 degrees below zero" as a signed number.

-3

200

• Represent "2 3/4 degrees below zero" as a signed number. Write it as a decimal and as a fraction.

-2 3/4

300

• Order these temperatures from coldest to warmest: 3 degrees below zero, 2 3/4 degrees below zero, 6 degrees above zero. Show the ordered list.

-3, -2  3/4, 6

Number Lines

100

• On a number line, what signed numbers are 4 units away from 0? List both.
