NCERT Class 4 Mathematics Math-Mela: Chapter 13 — The Transport The Transport Museum Museum
This chapter, 'The Transport Museum' from NCERT's Class 4 Mathematics Math-Mela, introduces multiplication concepts through engaging activities. Students will explore 'Mystery Matrices' where they fill in missing multiplicands, multipliers, and products, reinforcing their understanding of multiplication facts. The chapter also covers 'Times-10' concepts, showing how multiplying by 10 relates to tens and hundreds, and introduces the idea of constructing multiplication tables. A key activity involves calculating the total number of items in an arrangement by splitting it into simpler multiplication problems, such as 5 x 15 being broken down into 5 x 10 and 5 x 5. This chapter aims to build a strong foundation in multiplication for CBSE students.

- Fill in the blanks: 3 x 10 = ______ Tens = ______ Answer: 3 Tens = 30
- What is the product of 7 and 10? Answer: 70
- If you have 4 rows of 5 pebbles each, how many pebbles are there in total? (Use splitting: 4 x 5 = 4 x 2 + 4 x 3) Answer: 4 x 5 = 8 + 12 = 20 pebbles

Frequently asked questions
What is a Mystery Matrix in this chapter?
A Mystery Matrix is a grid where students fill in 1-digit numbers as multiplicands and multipliers to achieve given products, and then fill in the remaining products.
How does the chapter explain 'Times-10'?
The chapter explains that multiplying a number by 10 results in that number of 'Tens', and 10 Tens make 1 Hundred.
What strategy is used for constructing tables?
The chapter uses the strategy of splitting the number being multiplied into smaller, easier parts to find the product.
How can we find the total number of pebbles in a 5 x 15 arrangement?
We can split 15 into 10 and 5, then calculate 5 x 10 and 5 x 5 separately, and add the results: 50 + 25 = 75.
What is the product of 10 x 10?
The product of 10 x 10 is 100, which is equal to 10 Tens.
