Steps to Multiply Whole Tens by Whole Tens for Grade 4 Students
FAQs on Multiplying Whole Tens by Whole Tens – Class 4 Maths Worksheet
1. What is the easiest way to multiply whole tens by whole tens?
The simplest method to multiply whole tens by whole tens (e.g., 40 × 70) involves a quick, three-step mental math trick.
- First, multiply only the non-zero digits at the beginning of each number (4 × 7 = 28).
- Next, count the total number of zeros in both of the original numbers (one from 40 and one from 70, which is two zeros).
- Finally, add those zeros to the end of your result (28 becomes 2800). So, 40 × 70 = 2800.
2. What is the purpose of a 'multiply whole tens by whole tens' worksheet for Class 4?
This Class 4 maths worksheet is designed to build a strong foundation in multiplication, making it easier for students to handle more complex two-digit multiplication later.

5. What key skills does my child learn from practicing multiplying by multiples of 10?
Practicing with this worksheet helps a Grade 4 student develop several essential mathematical skills beyond basic calculation.
- Place Value Understanding: Students learn how the position of a digit affects its value, a key concept for all future math.
- Mental Math: It encourages solving problems without a calculator, building confidence and speed.
- Pattern Recognition: Students begin to see patterns in multiplying by 10s, which aids in problem-solving.
- Foundation for Larger Multiplication: Mastering this skill is a prerequisite for tackling multiplication of larger numbers.
6. How does understanding place value help in multiplying whole tens?
Understanding place value is fundamental to the strategy for multiplying whole tens. It allows students to decompose numbers and see the logic behind the multiplication shortcut.
- For example, a student recognizes that 40 is not just '4' and '0' but represents 4 tens.
- Similarly, 70 represents 7 tens.
- Therefore, the problem 40 × 70 is conceptually the same as (4 × 10) × (7 × 10), which simplifies to (4 × 7) × (10 × 10), or 28 × 100 = 2800.
7. Can this maths worksheet be used on a tablet or is it for printing only?
This worksheet is primarily designed as a printable maths worksheet for easy use with a pen or pencil. However, since it is a free maths worksheet PDF, you can also open it on a tablet or computer and use digital annotation tools or apps to fill in the answers directly on the screen.
