Inequalities Level G: Advanced mathematical statements that compare two numbers using symbols like greater than (>), less than (<), or equal (=). At Level G, students work with numbers up to 20 and understand solution concepts.
Greater Than (>): One number is bigger than another
Less Than (<): One number is smaller than another
Equal (=): Two numbers are the same
Inequality: A comparison between two numbers using >, <, or =
Solution: Finding which number makes the inequality true
Level G: Advanced understanding with numbers up to 20
• Comparison Rule: Compare numbers to see which is bigger or smaller
• Symbol Rule: Use > when left number is bigger, < when right number is bigger
• Equality Rule: Use = when both sides are the same
• Verification Rule: Always check your answer makes sense
• Level G Rule: Work with numbers up to 20 and understand solution concepts
- Look at the numbers: Identify the two numbers being compared
- Count or compare: Determine which number is bigger or smaller
- Choose the symbol: Select >, <, or = based on comparison

- Check work: Verify your answer is correct
- Level G Verification: Understand that this is a solution to the inequality
Example 1: Compare 5 and 3
5 is greater than 3, so 5 > 3
Example 2: Compare 2 and 7
2 is less than 7, so 2 < 7
Example 3: Compare 4 and 4
4 is equal to 4, so 4 = 4
Example 4: Compare 15 and 12
15 is greater than 12, so 15 > 12
Example 5: Compare 8 and 18
8 is less than 18, so 8 < 18
Example 6: Compare 16 and 16
16 is equal to 16, so 16 = 16

• Level G Mastery: Practice with numbers up to 20 for advanced understanding
Students should master comparing numbers up to 20, understanding inequality symbols, verifying their solutions, and developing confidence with larger numbers.
Greater Than (>): The left number is bigger than the right number
- Look at the numbers: 17 and 14
- Compare: 17 is bigger than 14
- Choose symbol: Use > because 17 is greater
- Write inequality: 17 > 14
- Verify: 17 is indeed bigger than 14
- Level G Verification: This is the correct solution for the inequality
We have 17 and 14 to compare. (Level G challenge: working with numbers up to 20)
17 is bigger than 14.
Since 17 is bigger, we use > (greater than).
17 > 14
Yes, 17 is greater than 14, so our answer is correct.
This is the correct solution for the inequality 17 ? 14.
The correct inequality is 17 > 14.
• Comparison Rule: Compare numbers to see which is bigger
• Symbol Rule: Use > when left number is bigger
• Verification Rule: Checked that 17 is indeed greater than 14
• Level G Rule: Worked with numbers up to 20
Less Than (<): The left number is smaller than the right number
We have 9 and 16 to compare. (Level G challenge: working with numbers up to 20)
9 is smaller than 16.
Since 9 is smaller, we use < (less than).
9 < 16
Yes, 9 is less than 16, so our answer is correct.
This is the correct solution for the inequality 9 ? 16.
The correct inequality is 9 < 16.
• Comparison Rule: Compare numbers to see which is smaller
• Symbol Rule: Use < when left number is smaller
• Verification Rule: Checked that 9 is indeed less than 16
• Level G Rule: Worked with numbers up to 20
Equal (=): Both numbers are exactly the same
We have 13 and 13 to compare. (Level G challenge: working with numbers up to 20)
13 is equal to 13.
Since both numbers are the same, we use = (equal).
13 = 13
Yes, 13 is equal to 13, so our answer is correct.
This is the correct solution for the inequality 13 ? 13.
The correct inequality is 13 = 13.
• Equality Rule: Use = when both numbers are the same
• Verification Rule: Checked that both numbers are equal
• Level G Rule: Worked with numbers up to 20
Greater Than (>): The left number is bigger than the right number
We have 19 and 15 to compare. (Level G challenge: working with numbers up to 20)
19 is bigger than 15.
Since 19 is bigger, we use > (greater than).
19 > 15
Yes, 19 is greater than 15, so our answer is correct.
This is the correct solution for the inequality 19 ? 15.
The correct inequality is 19 > 15.
• Comparison Rule: Compare numbers to see which is bigger
• Symbol Rule: Use > when left number is bigger
• Verification Rule: Checked that 19 is indeed greater than 15
• Level G Rule: Worked with numbers up to 20
Less Than (<): The left number is smaller than the right number
We have 7 and 18 to compare. (Level G challenge: working with numbers up to 20)
7 is smaller than 18.
Since 7 is smaller, we use < (less than).
7 < 18
Yes, 7 is less than 18, so our answer is correct.
This is the correct solution for the inequality 7 ? 18.
The correct inequality is 7 < 18.
