What is Class 3 Maths Chapter 9 House of Hundreds II?

Chapter 9 of the NCERT Class 3 Maths book Maths Mela is called House of Hundreds II. It is about numbers up to 1000. Children already know that 10 tens make 100. Here they see that 10 hundreds make 1000, that numbers can be placed and compared on a number line, and that the same number can be made in many ways.

Numbers up to 1000 with place value

A 3-digit number has hundreds, tens and ones. For 832 there are 8 hundreds, 3 tens and 2 ones, so 832 is 800 + 30 + 2. If a place has nothing, we write 0. In 504 there are no tens. In 620 there are no ones. In 700 there are no tens and no ones.

Number lines up to 1000

To find a number on a number line first read the numbers at the two ends and the size of one step. On a line from 500 to 700 with steps of 20 the ticks are 500, 520, 540, 560 and so on. To find 660 on a line from 600 to 700 with steps of 20, count 3 steps from 600. On a line from 695 to 875 with steps of 20, the ticks are 695, 715, 735, 755, 775 and so on. 775 is 4 steps after 695.

Neighbours of a number

The neighbours of a number are the numbers just before and just after it in a skip count. For 468 the neighbouring hundreds are 400 and 500. The neighbouring fifties are 450 and 500. The neighbouring tens are 460 and 470. Neighbours tell us how near a number is to a round number.

Crane puzzles on the number line

In the chapter a crane moves along a number line. From 667 a step back of 17 reaches 650, because 667 − 17 = 650. From 667 a step forward of 33 reaches 700, because 667 + 33 = 700. A good way is to jump to the nearest ten first and then to the hundred. From 667 jump 7 back to 660, then 10 back to 650.

Tambola and clues

In Tambola a number is called out and players cross it off. The chapter gives clues for numbers between 570 and 630, such as a number with the digit 4, a number between 595 and 605, a number with 1 as the tens digit, two more than 610 and 5 less than 625. Each clue narrows the choices until only one number fits.

Making a number in different ways

The same number can be made in many ways. 368 is 300 + 60 + 8. It is also 68 more than 300, 400 − 32 and 32 less than 400. Choosing a friendly number such as 300 or 400 and then adding or taking away makes the sum easy.

Skip patterns

In a skip pattern the numbers grow by the same jump each time. The chapter uses jumps of 10, 100, 25, 30 and 15. 340, 440, 540 grows by 100, so the next is 640. 830, 855, 880 grows by 25, so the next is 905. Children also fill the numbers from 940 to 1000 in jumps of 10.

Number puzzles and ranges

Number sentences with a missing number ask children to think about size. 290 + 110 = 400 and 750 + 25 = 775. Some puzzles give conditions such as a number between 385 and 436. Children also match quantities to ranges: 0 to 10, 11 to 50, 51 to 100, 101 to 200, 201 to 500, 501 to 1000 and more than 1000. A rough idea of how large a number is helps to guess how many.

Digit riddles and special numbers

Riddles give clues about digits. A 3-digit number with 2 zeroes close to 99 is 100. A number with 3 hundreds, 6 tens and 7 ones is 367. A century and a half century together make 150. In Number Detective children spot all-hundreds numbers such as 300, numbers whose digits go up by 1 such as 789 and 345, twin digit numbers such as 11 and 22, triplet digit numbers such as 111 and 222, palindromes such as 353 and 868, and numbers with zeroes such as 210, 404 and 800.

Slips of 100, 10 and 1, and the digits 3 and 8

With 6 slips that say 100, 10 or 1, the biggest number is 600 (six slips of 100). To make 231 use 2 slips of 100, 3 slips of 10 and 1 slip of 1. In another task children use only the digits 3 and 8. The 2-digit numbers are 33, 38, 83 and 88. The 3-digit numbers can repeat digits, such as 333, 338, 383, 388, 833, 838, 883 and 888. Children arrange them from the smallest to the greatest.

Types of questions to practise

Questions on this chapter ask children to read numbers from bundles, write number names, find numbers on a number line, give the neighbouring hundreds, fifties and tens, make a number in different ways, continue skip patterns, solve riddles and make numbers from digits. The online quiz on this page mixes choice questions, true or false questions, picture questions and typed answers, and the practice sheet has 16 typed answers.

Solved examples

Common mistakes

Numbers up to 1000 in daily life

We meet these numbers in page numbers, house numbers, bus numbers, prices in rupees and distances on a signboard. Ask your child to read the number on a bus, to say the nearest hundred and to say which of two prices is greater. Ask how many 100 rupee notes make 1000 rupees.

Tips for parents and teachers

Draw a long number line on the floor with chalk and let your child walk to a number. Use rubber bands and sticks to make real bundles of 10 and 100. Play a Tambola game with number cards and clues. Ask your child to make the same number in three different ways, for example with plus, with minus and with more or less.
