Draw box diagrams, as shown above to solve the following problems. Then use HTO blocks or a number line to solve the problems.
Question 1.
Kishan has 456 saplings in August. He distributed 63 saplings. How many saplings are left with him?
Answer:
Box diagram for the problem:
Let us represent 456 saplings using HTO blocks.
We have to subtract 63 from 456. Take away 3 ones from 6 ones.
Now, to take away 6 tens from 5 tens, change 1 hundred into 10 tens. Now we can take away 6 tens from 15 tens. Subtract 6 tens from 15 tens, we one left 9 tens and 3 hundreds.
Thus, Kishan left 393 saplings with him.
Using number line
Question 2.
Kishan has a collection of 309 saplings. He gets 80 more saplings of flowering plants. How many saplings does he have now?
Answer:
Box diagram for the problem:
Let us represented 309 and 80 using HTO block and add them to find the total numbers of saplings.
Combining hundreds, tens and ones blocks as 309 + 80 = 389
Thus, 309 saplings + 80 saplings = 389 saplings
309 + 80 = 389
Also, by using a number line
Question 3.
Kishan has 270 saplings of herbs and his friend has 36 saplings of herbs. How many more saplings does Kishan have than his friend?
Answer:
Box diagram for the problem:
Let us represent 270 using HTO blocks.
To find the number of more sapling Kishan has than his friend subtract 36 from 270.
To subtract 6 ones, change 1 ten from 7 tens into ones.
Take away 6 ones from 10 ones and 3 tens from the remaining 6 tens.
Thus, 270 – 36 = 234
Thus, Kishan has 234 saplings more than his friend.
