How to Add Whole Tens to Single-Digit Numbers with Examples
FAQs on Adding Whole Tens to Two 1-Digit Numbers – Class 2 Practice Worksheet
1. What is meant by 'adding whole tens to a one-digit number'?
Adding whole tens to a one-digit number is a basic addition skill where you combine a number made of only tens (like 10, 20, or 30) with a single-digit number (like 1, 2, or 3). This concept is a key part of the Class 2 Maths syllabus and helps build a strong understanding of place value. For example, in the sum 40 + 5, you combine 4 tens with 5 ones to get the answer 45. This worksheet focuses on this specific type of addition without regrouping.
2. How do you add whole tens to a number easily?
To add a whole ten to a single-digit number, you can use a simple trick based on place value: simply replace the zero in the ones place of the tens number with the single-digit number you are adding. For example:
- In the sum 30 + 7, the 7 (ones) replaces the 0 (ones) in 30, making the answer 37.
- In the sum 50 + 4, the 4 replaces the 0, making the answer 54.
3. What is an example of adding tens and ones?
A common example of adding tens and ones is combining a number like 40 (four tens) with a number like 6 (six ones) to get 46. This Grade 2 addition worksheet provides many practice sums to master this concept. Some typical examples include:
- 20 + 8 = 28 (which is 2 tens and 8 ones)
- 60 + 3 = 63 (which is 6 tens and 3 ones)
- 80 + 9 = 89 (which is 8 tens and 9 ones)
4. What skills are built by this addition worksheet for Class 2?
This worksheet helps Class 2 students build fundamental math skills including addition fluency, number sense, and mental math capabilities. By completing the maths sums for Class 2, students strengthen their understanding of several key areas:
- Place Value: Recognising the value of tens and ones in a number.
- Mental Math: Quickly solving simple addition problems without writing them down.
- Number Sense: Developing an intuition for how numbers are composed.
- Addition Fluency: Building speed and accuracy for more complex future math problems.
5. How can I use this Grade 2 addition worksheet at home?
You can easily use this worksheet at home for extra practice, homework support, or holiday revision. Simply follow these steps:
- Download the free PDF file to your computer or mobile device.
- Print the worksheet for your child to solve with a pencil.

- A variety of problems, such as simple sums and fill-in-the-blank questions.
- Visual aids like tens rods and units to support understanding.
- A focus on specific skills like adding whole tens or addition without regrouping.
7. How does adding tens and ones help with understanding place value?
Practising the addition of tens and ones directly reinforces the concept of place value by showing how two-digit numbers are constructed. When a child solves a problem like 50 + 6 = 56, they are actively learning that:
- The digit 5 is in the tens place and represents 50.
- The digit 6 is in the ones place and represents 6.
- Combining them creates a new number, building a strong foundation for understanding the tens and units system.
