# 👨👩👧 Parent Tip
When your child gets a question wrong, don't immediately say:
**"Wrong!"**
Instead ask:
**"Let's see where we went wrong."**
Then ask:
- What information is given?
- What do we need to find?
- Which operation should we use?
- Can we draw it?
- Can we solve it another way?
This develops independent problem-solving skills.
