How to use this worksheet. This is your first check-in for the winter course. It is all about positive and negative numbers — money, temperature, and moving along the number line.
- Two things to do: write the number on the answer lines, and circle the correct answer where you see choices. Read each one carefully first.
- Every part has a Clarify hint. Try the part yourself first; only read the hint if you get stuck. It shows you how to start — it never gives the answer.
- There are two versions (A and B). Do the version your mentor points you to. Take your time — neatness helps.
Version A
PART 1
Real Life Numbers
Write the number. Use a plus sign (+) or a minus sign (−).
1.You owe your friend $5.
2.The temperature is 10 degrees below zero.
3.You find $8 on the ground.
4.A football player loses 3 yards.
5.You earn $20 for working.
Clarify — Method: decide the direction before you write anything. Ask, "Does this go up from zero, or down below zero?" Words like owe, below, loses point one way; words like find, earn point the other. Then write the matching sign in front of the number.
PART 2
Big and Small
Circle the correct answer.
6.Circle the number that is smaller:
a) 4b) −2
7.Circle the number that is bigger:
a) −1b) −10
8.Circle the number that is smaller:
a) 0b) 3
9.Put these in order from smallest to biggest: −5, 2, 0
10.Which is colder?
a) −2 degreesb) −8 degrees
Clarify — Method: picture the number line. Whatever sits farther to the left is the smaller number; farther to the right is bigger. "Colder" means the lower temperature. Find each number's spot first, then compare.
PART 3
The Number Line
Use the number line below to help you move.
<--- −5 --- −4 --- −3 --- −2 --- −1 --- 0 --- 1 --- 2 --- 3 --- 4 --- 5 --->
11.Start at 0. Move 4 steps to the left. Where are you?
12.Start at 2. Move 3 steps to the right. Where are you?
13.Start at −1. Move 2 steps to the left. Where are you?
14.Start at −3. Move 3 steps to the right. Where are you?
15.How many steps is it from −2 to 2?
Clarify — Method: put your finger on the starting number first. "Left" means count down, "right" means count up. Move one step at a time and read where your finger lands. For the last one, count each hop between the two numbers.
PART 4
Math Language
Circle the correct answer or solve.
16.Is 4 + 2 an Expression or an Equation?
ExpressionEquation
17.Is 5 + 5 = 10 an Expression or an Equation?
ExpressionEquation
18.Solve: 5 + (−2)
19.Solve: −3 + 1
20.True or False: A negative number is always smaller than a positive number.
TrueFalse
Clarify — Method: look for the equals sign. An equation has an = in it; an expression does not. For the "Solve" problems, use your number line — adding a negative means moving left from the first number.
Version B
PART 1
Real Life Numbers
Write the number. Use a plus sign (+) or a minus sign (−).
1.You owe your friend $9.
2.The temperature is 4 degrees below zero.
3.You find $5 on the ground.
4.A football player loses 7 yards.
5.You earn $15 for working.
Clarify — Method: decide the direction before you write anything. Ask, "Does this go up from zero, or down below zero?" Words like owe, below, loses point one way; words like find, earn point the other. Then write the matching sign in front of the number.
PART 2
Big and Small
Circle the correct answer.
6.Circle the number that is smaller:
a) 6b) −3
7.Circle the number that is bigger:
a) −2b) −20
8.Circle the number that is smaller:
a) 0b) 5
9.Put these in order from smallest to biggest: −3, 4, 0
10.Which is colder?
a) −5 degreesb) −1 degrees
Clarify — Method: picture the number line. Whatever sits farther to the left is the smaller number; farther to the right is bigger. "Colder" means the lower temperature. Find each number's spot first, then compare.
PART 3
The Number Line
Use the number line below to help you move.
<--- −5 --- −4 --- −3 --- −2 --- −1 --- 0 --- 1 --- 2 --- 3 --- 4 --- 5 --->
11.Start at 0. Move 6 steps to the left. Where are you?
12.Start at 3. Move 4 steps to the right. Where are you?
13.Start at −2. Move 3 steps to the left. Where are you?
14.Start at −5. Move 5 steps to the right. Where are you?
15.How many steps is it from −3 to 3?
Clarify — Method: put your finger on the starting number first. "Left" means count down, "right" means count up. Move one step at a time and read where your finger lands. For the last one, count each hop between the two numbers.
PART 4
Math Language
Circle the correct answer or solve.
16.Is 8 − 3 an Expression or an Equation?
ExpressionEquation
17.Is 2 + 2 = 4 an Expression or an Equation?
ExpressionEquation
18.Solve: 6 + (−2)
19.Solve: −4 + 1
20.True or False: A positive number is always bigger than zero.
TrueFalse
Clarify — Method: look for the equals sign. An equation has an = in it; an expression does not. For the "Solve" problems, use your number line — adding a negative means moving left from the first number.
