Far and Near - Class 5 Mathematics (CBSE)
Based on the current NCERT Maths Mela Grade 5 sequence. Read the idea, try the activity, then solve the practice set without looking at the answers.
1. Why this chapter matters
Far and Near uses familiar Class 5 situations to make mathematics feel usable. Instead of treating maths as a list of sums, this chapter asks students to notice information, choose a method, explain the method, and check whether the answer makes sense.
The main focus is estimating and comparing distances in familiar surroundings. This is useful in notebooks, oral questions, class activities, and competency-based school tests because teachers often ask students to explain how they know, not just write the final number.
2. Core ideas
Idea 1
Near and far depend on the reference point.
Method 2
Large distances need suitable units such as kilometres.
Skill 3
Estimation helps when exact measurement is not possible.
3. Worked examples
Example 1: Which unit is better for distance between two cities: cm or km?
Kilometre, because cities are far apart.
Check: The answer uses the correct operation and keeps the unit or context clear.
Example 2: A shop is 600 m away and a park is 1 km away. Which is nearer?
600 m is nearer because 1 km = 1000 m.
Check: The answer uses the correct operation and keeps the unit or context clear.
4. Activity corner
Make a near-to-far list of five places around you: desk, classroom door, school gate, market, and city station.
Write your activity answer in three parts:
- What I observed
- What I calculated or compared
- What mathematical idea this shows
5. Common mistakes
- Mistake: Solving before reading the whole word problem Fix: Circle the data, underline the question, and then choose the operation.
- Mistake: Forgetting units such as cm, m, kg, L, minutes, or rupees Fix: Write the unit with every final answer.
- Mistake: Doing only exact calculation without checking reasonableness Fix: Use estimation or reverse operation to catch impossible answers.
6. How to write better answers
- Write the given numbers and units first.
- Show the operation or reasoning step.
- Use a diagram, table, grid, or number line if it makes the answer clearer.
- Write the final answer in a complete sentence.
- Check the answer by estimation, reverse operation, or common sense.
7. Practice set
- Which is longer: 1 km or 500 m?
- What is a reference point?
- Arrange 20 m, 2 km, and 200 m from near to far.
- Why can the same place feel near to one person and far to another?
- Name one way to estimate distance in school.
- If 1 round of a ground is 250 m, how far are 4 rounds?
8. Answer key
-
Which is longer: 1 km or 500 m? Answer: 1 km, because it is 1000 m.
-
What is a reference point? Answer: The place from which distance or direction is judged.
-
Arrange 20 m, 2 km, and 200 m from near to far. Answer: 20 m, 200 m, 2 km.
-
Why can the same place feel near to one person and far to another? Answer: They may start from different locations or travel differently.
-
Name one way to estimate distance in school. Answer: Count steps and multiply by average step length.
-
If 1 round of a ground is 250 m, how far are 4 rounds? Answer: 1000 m, or 1 km.
9. Quick revision
- Main focus: estimating and comparing distances in familiar surroundings.
- Near and far depend on the reference point.
- Large distances need suitable units such as kilometres.
- Estimation helps when exact measurement is not possible.
- Learn by doing the activity once, not by memorising only the final answers.
- Keep units clear and show steps for partial marks.
