# 👨👩👧 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.

---

# 📈 Maintain a Progress Tracker

Parents can use a simple table:

| Test | Score | Accuracy | Weak Topic |
|---|---:|---:|---|
| Test 1 | 12/20 | 60% | Fractions |
| Test 2 | 14/20 | 70% | Time |
| Test 3 | 16/20 | 80% | Division |
| Test 4 | 18/20 | 90% | Reasoning |
