🌟 Representing Inequalities on a Number Line 🌟

Hi my amazing Grade 6 number line experts! 🌟

Today we’re learning how to show inequalities on a number line! This helps us see the solution clearly — like marking where the answers live. Open circles and closed circles are very important. Let’s draw and understand together! 📏

1. Quick Reminder of Inequality Symbols

> greater than < less than
≥ greater than or equal to ≤ less than or equal to

2. How to Represent on a Number Line

x > 3

Open circle at 3 (not including 3) and arrow going right →

←———○——————→
3

x ≤ 5

Closed circle at 5 (including 5) and arrow going left ←

←————●——————
5

3. More Examples

x ≥ -2
Closed circle at -2, arrow to the right

x < 0
Open circle at 0, arrow to the left

4. Let’s Practice Together! 🎉

Question 1:

Draw the number line for: x > 4

Open circle at 4, arrow pointing right → ⭐

Question 2:

Draw the number line for: x ≤ 2

Closed circle at 2, arrow pointing left ← ⭐

Question 3:

Which inequality matches this number line?
Closed circle at -1 with arrow to the right

x ≥ -1 ⭐

Question 4:

You must be at least 12 years old to enter. Show this on a number line.

Closed circle at 12, arrow to the right (age ≥ 12) ⭐

Question 5 (Real Life):

The temperature is below -5°C. Show this inequality on a number line.

Open circle at -5, arrow pointing left (t < -5) ⭐

6. Real Life in Canada 🇨🇦

You need to be taller than 110 cm for a ride
Temperature must be below 0°C to skate on a pond
You need at least $50 to buy a new hockey stick
School starts if the temperature is above -20°C

You are a Number Line Inequalities Expert! 🏆

Fantastic job today! You can now show inequalities clearly on a number line.

This skill helps you understand and solve many real-life math problems.

I’m so proud of you!

Keep practicing with temperatures and ages,
Mrs. Brenda ❤️
