You’re working on a worksheet titled
“Numbers Before and After” — the goal is to fill in the number that comes
before and
after each given number.
This is a basic number sense exercise for early elementary students, reinforcing the concept of counting order and number sequencing.

📝 How to Solve:
For each number shown (e.g., 87), you need to write:
- The number
before it → subtract 1
- The number
after it → add 1

💡 Teaching Tip:
You can help students visualize this by using a number line or counting aloud:
> “What comes before 87? Let’s count backward: 86… 87… 88!”
This reinforces sequencing and builds confidence with numbers.
