Chapter 13 of the Class 4 Maths textbook Math Mela is The Transport Museum. Set around a visit to a transport museum, it teaches multiplication techniques — splitting and doubling numbers — to build times tables and solve travel-related word problems.
Multiplying by Splitting
Q: How can splitting help you find 6 × 14?
A: Split 14 into 10 + 4. Then 6 × 14 = (6 × 10) + (6 × 4) = 60 + 24 = 84.
Multiplying by Doubling
Q: How can doubling help you find 3 × 14 using 6 × 14?
A: Since 6 = 3 × 2, if you already know 3 × 14 = 42, you can double it: 6 × 14 = 2 × 42 = 84. Doubling a known multiplication fact is a quick way to find a related one.
Building Times Tables
Q: How does knowing the 2-times table help you build the 4-times table?
A: Since 4 = 2 × 2, each entry in the 4-times table is double the matching entry in the 2-times table (e.g. 4 × 5 = 2 × (2 × 5) = 2 × 10 = 20).
Travel Word Problems
Q: If one bus at the museum can carry 14 visitors, how many visitors can 6 buses carry in total?
A: 6 × 14 = 84 visitors.
Frequently Asked Questions
What multiplication strategies does this chapter focus on?
Splitting a number into parts (like tens and ones) and doubling a known multiplication fact, both used to make multiplication easier without long calculation.
Why is the chapter set in a transport museum?
It provides a real-world, engaging context (buses, vehicles, visitor counts) for practising multiplication word problems.
