Questions and Solutions
Q1: Write the number
Write the number shown by the TENS and ONES columns.
TENS ONES TENS ONES
TENS ONES TENS ONES
TENS ONES TENS ONES
TENS ONES TENS ONES 3 4
TENS ONES TENS ONES 4 6
TENS ONES TENS ONES 2 0
To write the number, we look at the digits in the TENS and ONES columns. The digit in the TENS column tells us how many groups of ten we have, and the digit in the ONES column tells us how many individual items we have left over.
- For the first set of columns showing '3' in TENS and '4' in ONES, we have 3 tens and 4 ones. This makes the number 34.
- For the second set of columns showing '4' in TENS and '6' in ONES, we have 4 tens and 6 ones. This makes the number 46.
- For the third set of columns showing '2' in TENS and '0' in ONES, we have 2 tens and 0 ones. This makes the number 20.
The numbers are: 34, 46, 20.
Q2: Draw the bundles.
Draw the bundles to represent the given numbers.
TENS ONES
TENS ONES 43
TENS ONES
TENS ONES 22 -
To draw the bundles, we need to represent the tens and ones for each number. A bundle represents ten items, and loose items represent ones.
For the number 43:
- The digit '4' is in the TENS place, so we need 4 bundles of ten.
- The digit '3' is in the ONES place, so we need 3 loose items.
We draw 4 bundles and 3 individual items.
TENS ONES
TENS ONES 43 3 For the number 22:
- The digit '2' is in the TENS place, so we need 2 bundles of ten.
- The digit '2' is in the ONES place, so we need 2 loose items.
We draw 2 bundles and 2 individual items.
TENS ONES
TENS ONES 22 2
Common mistakes
- Confusing the order of tens and ones.
- Incorrectly drawing bundles or making groups.
- Misinterpreting the number represented by tens and ones.
Revision tips
- Practice writing numbers by identifying tens and ones in the given examples.
- Use physical objects like beads or sticks to create bundles and practice representing numbers.
- Review the place value concept regularly to avoid confusion between tens and ones.
- Attempt all exercises to ensure a thorough understanding of number representation.
Practice MCQs
Q1. In the number 34, how many tens are there?
Explanation: The number 34 has 3 tens and 4 ones. The digit in the tens place represents the number of tens.
Q2. If you have 4 bundles of ten and 6 loose items, what number do you have?
Explanation: Four bundles of ten represent 4 tens (40), and 6 loose items represent 6 ones. Together, they form the number 46.
Q3. How many ones are in the number 20?
Explanation: The number 20 has 2 tens and 0 ones. The digit in the ones place indicates the number of ones.
Q4. To represent the number 43, you would draw:
Explanation: The number 43 consists of 4 tens and 3 ones. Therefore, you draw 4 bundles of ten and 3 individual items.
