Question

$7$ carrots and $8$ tomatoes are picked from the farm. Fill in the empty boxes using the “make a $10$” strategy to find the number of vegetables picked in total.

• A. (i) 5; (ii) 2; (iii) 2; (iv) 15
• B. (i) 5; (ii) 2; (iii) 5; (iv) 15
• C. (i) 2; (ii) 5; (iii) 5; (iv) 15
• D. (i) 2; (ii) 5; (iii) 2; (iv) 15

Answer 1

The correct option is B (i) 5; (ii) 2; (iii) 5; (iv) 15

Say: Let’s read the question and observe the given incomplete solution.

Ask:
$\bullet$ Which two numbers do we need to add here?
Ans: $7$ and $8$
$\bullet$ How can we add these numbers using the said strategy?
Ans: To add $7$ and $8,$ i.e., $7+8$ using the “make a $10$” strategy, we break down $7$ into $5$ and $2.$ Next, $2$ and $8$ are added to make a $10$, and finally, $5$ and $10$ are added to get the total of $15.$
$\bullet$ What are the missing numbers?
Ans: (i) 5, (ii) 2, (iii) 5, and (iv) 15
$\bullet$ What is the total number of vegetables picked?
Ans: $15$
Hence, option A is the correct answer.
