Absolutely! Let’s solve
Activity 1: Working with Negative Numbers step by step. The number line provided (from -5 to +5) is a great visual tool to understand how negative numbers work — you can think of subtraction as moving left on the number line, and addition as moving right.
---
🔢 Key Rules to Remember:
-
Subtracting a positive number = move
left on the number line.
-
Adding a positive number = move
right on the number line.
-
Subtracting a negative number = same as adding a positive (not used here).
-
Adding a negative number = same as subtracting a positive (e.g., `+ (-3)` = `-3`).

💡 Tip for Understanding:
When you see something like `-2 + 5`, think: “I owe 2, but I get 5 — so I end up with 3.” Or use the number line — always start at the first number and move according to the second.
You’ve got this! Negative numbers are just numbers to the left of zero — they’re not scary, just directional 😊
Let me know if you’d like to visualize any of these on the number line!
Parent Tip: Review the logic above to help your child master the concept of negative numbers worksheet.
