When every group holds the same amount, multiply instead of adding.
When a word problem mentions that every packet, every can, every almirah, or every month holds the exact same amount, and it asks you to find the total for the whole, you are looking at a multiplication problem! You simply multiply the size of one group by the total number of groups.
Example 1 from page 38, laid out as the book lays it out.
In a library, there are books in each almirah. There are almirahs in the library. Find the total number of books in the library.
Example 2 from page 38, including the two-step part.
Rajat saves ₹ every month. How much money can he save (i) in months (ii) in four years?
Worksheet 4 items (a) and (d), in ordered steps.
Problem (a): There are toffees in a packet. How many toffees are there in packets?
Problem (d): One dozen bananas cost ₹. What is the cost of dozen bananas?
What does one group hold, and how many groups are there for each problem?
Which numbers do you need to multiply together?
Show the partial rows for your multiplication.
Add your partial products together for both problems.
State your final answers including their correct units (toffees / rupees).
The word 'dozen' appears in (d). Do you need to multiply by 12? Explain why or why not.
The oil cans, the beads and the book pages.
(b) A can of oil contains litres of oil. How much oil is there in such cans? (c) There are beads in a necklace. Find the total number of beads in such necklaces. (e) There are pages in a book. How many pages are there in such books?
Provide the three final answers with their correct units.
Show the labels you used for (b) and (c). For (e), explain how you can solve it orally rather than in columns.
Optional: Briefly note why providing only a bare number is insufficient in real-world problems.
