1. Writing Inequalities Continued

2. 6.EE.6 Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.
Objective: Understand how to describe real-life situations by using inequalities.
Learning target: Answer at least 3 out of 4 questions correctly on the exit ticket.

3. How do we know which inequality to use in a word problem?
Look for certain key words.
y > 5
y < 5
greater than
larger than
minimum
not less than
not smaller than
smaller than
less than
at most
not more than
not greater than
more than
maximum
at least
fewer than

4. What if none of the key words appear in the problem?
Use this flowchart:
Is the number in the problem a correct answer?
yes no
Since the number must be included, use either < or >
Is it okay to be less than the number or more than the number?
Since the number cannot be included, use either < or >
Is it okay to be less than the number or more than the number?
less
more
less
more
Use
<
Use
>
Use
<
Use
>

5. What are the steps for writing an inequality?
Step 1: Write down a variable and number from the problem, leaving a space for the symbol. Ex: y 8
Step 2: Choose a different number that is an answer for the problem. Below, replace the variable with that number.
Step 3: Write either > or < in between the numbers.
Step 4: If the number from the problem is allowed, add the _ to your symbol.

6. I am allowed to spend up to $30. Write an inequality.
Step 1: Write down a variable and number from the problem, leaving a space for the symbol.
Step 2: Choose a different number that is an answer for the problem. Below, replace the variable with that number.
Step 3: Write either > or < in between the numbers.
Step 4: If the number from the problem is allowed, add the _ to your symbol.

7. The second place team has 85 points
The second place team has 85 points. How many points does the first place team have?
Step 1: Write down a variable and number from the problem, leaving a space for the symbol.
Step 2: Choose a different number that is an answer for the problem. Below, replace the variable with that number.
Step 3: Write either > or < in between the numbers.
Step 4: If the number from the problem is allowed, add the _ to your symbol.

8. If I make 4 mistakes, I fail. How many mistakes am I allowed to make?
Step 1: Write down a variable and number from the problem, leaving a space for the symbol.
Step 2: Choose a different number that is an answer for the problem. Below, replace the variable with that number.
Step 3: Write either > or < in between the numbers.
Step 4: If the number from the problem is allowed, add the _ to your symbol.

9. I will earn at least $50 tomorrow.
Step 1: Write down a variable and number from the problem, leaving a space for the symbol.
Step 2: Choose a different number that is an answer for the problem. Below, replace the variable with that number.
Step 3: Write either > or < in between the numbers.
Step 4: If the number from the problem is allowed, add the _ to your symbol.

10. Direct Station
We will use whiteboards/Educreations to look at more real-life situations and write inequalities based on the word problems.

11. Collaborative/Skill-Building Station
On your iPad, go to my staff webpage and click Links for April 25. MAKE SURE YOUR SOUND IS OFF
Click on the Collaborative Station link to go to a boxing game with inequalities.
If you beat the game you may go to the Activities for Early Finishers and play one of those games.

12. Independent Station
Again, go to my staff webpage and click on Links for April 24
Click on the independent station link to do this activity
If you get all 5 correct at least two times you may do ST Math instead.
