We the Travellers-II - 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
We the Travellers-II 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 extending travel maths with schedules, maps, distances, costs, and multi-step problems. 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
A schedule helps compare start time, end time, and duration.
Method 2
Multi-step travel questions need one operation at a time.
Skill 3
Maps use symbols and scales to simplify real places.
3. Worked examples
Example 1: A train leaves at 6:40 and reaches at 9:10. Find duration.
From 6:40 to 8:40 is 2 hours; to 9:10 is 30 minutes. Total 2 h 30 min.
Check: The answer uses the correct operation and keeps the unit or context clear.
Example 2: Three tickets cost Rs 45 each. What is the total?
45 x 3 = Rs 135.
Check: The answer uses the correct operation and keeps the unit or context clear.
4. Activity corner
Collect a bus or metro timetable. Choose two stops and calculate the travel duration between them.
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
- How many minutes are there from 3:15 to 4:00?
- If one ticket is Rs 18, find the cost of 5 tickets.
- What does a map symbol do?
- Why should we estimate travel time?
- A route has 12 km, 9 km, and 16 km parts. Find total distance.
- How do you solve a multi-step travel problem?
8. Answer key
-
How many minutes are there from 3:15 to 4:00? Answer: 45 minutes.
-
If one ticket is Rs 18, find the cost of 5 tickets. Answer: 18 x 5 = Rs 90.
-
What does a map symbol do? Answer: It represents a place or feature in a small, clear way.
-
Why should we estimate travel time? Answer: To plan when to leave and avoid being late.
-
A route has 12 km, 9 km, and 16 km parts. Find total distance. Answer: 37 km.
-
How do you solve a multi-step travel problem? Answer: Read carefully, list given data, solve one step at a time, and check units.
9. Quick revision
- Main focus: extending travel maths with schedules, maps, distances, costs, and multi-step problems.
- A schedule helps compare start time, end time, and duration.
- Multi-step travel questions need one operation at a time.
- Maps use symbols and scales to simplify real places.
- Learn by doing the activity once, not by memorising only the final answers.
- Keep units clear and show steps for partial marks.
