Chapter 8, Fun with Numbers, introduces two-digit numbers and place value using tens and ones. These questions revisit reading, comparing and building such numbers.
Practice Questions
Q1. Write 47 as tens and ones.
47 = 4 tens and 7 ones.
Q2. Which number is bigger, 68 or 86?
86 is bigger than 68.
Q3. What number comes right after 99?
100.
Q4. Arrange these numbers in increasing order: 34, 12, 58.
12, 34, 58.
Q5. Write the number that has 7 tens and 2 ones.
72.
Why These Help
Understanding tens and ones shows children that a number like 47 is really “4 groups of ten plus 7 more,” which is the idea behind how our whole number system is built.
Frequently Asked Questions
Q. Why is understanding tens and ones important for two-digit numbers?
It shows that any two-digit number is built from groups of ten plus some extra ones, which is the core idea behind place value used throughout later arithmetic.
