### STEP 1 – Understand

Read the question carefully.

### STEP 2 – Identify

Find out what the question is asking.

### STEP 3 – Plan

Choose the correct mathematical operation.

### STEP 4 – Calculate

Solve carefully.

### STEP 5 – Check

See whether the answer makes sense.

### STEP 6 – Learn

If you make a mistake, understand why.

---

# ⏰ 30-MINUTE DAILY MATHS ROUTINE

### 10 minutes
Number and calculation practice

### 10 minutes
Fractions, measurement or geometry

### 5 minutes
Word problems

### 5 minutes
One HOTS question

Regular practice can help build confidence and accuracy.

---

# 👨👩👧 PARENT TIP

When your child gets an answer wrong, don't immediately say:

**"Wrong!"**

Instead ask:

**"Let's check your first step."**

Then ask:

**"Which operation did you choose?"**

**"Why did you choose it?"**

This helps the child identify the mistake independently.

# 🎯 EVERYDAY MATHS CHALLENGE

Parents can connect mathematics with everyday activities.

For example:

### Shopping

Ask:

"If this costs ₹75 and we buy 3, how much will we pay?"

### Time

Ask:

"If school starts at 8:00 AM and ends at 2:00 PM, how long is school?"

### Measurement

Ask:

"How many centimetres are there in 2 metres?"

### Fractions

Ask:

"If a pizza has 8 equal pieces and we eat 3, what fraction remains?"

Mathematics becomes much easier when children see it in everyday life.
