Work on this page focuses on adding numbers that are divisible by ten.

This is a selection of worksheets and lessons that will help students learn how to add 10s together. Adding by 10s is usually a new concept for younger students. Show them real world examples of large numbers or start by add years. Place values are the fundamental aspect that helps this topic go very smoothly. Give them a large number like how much a favorite athlete or rock band made last year. For instance, LeBron James made $30,960,000 in 2017. Break down all the places ten-millions, millions, hundred-thousands, ten-thousands, thousands, hundreds, tens, ones. This type of example really sparks interest. You can find a standard worksheets for this section on the very bottom. Otherwise, each worksheet progresses from the simple places, to counting, to positioning the student for full on learning.

How to Practice Adding by 10s?

The process of adding by 10s is a great way to introduce kids to two-digit addition. It's also an excellent way to review the concept with older kids. And it can be used as a strategy for solving more difficult addition problems. Learning to add by 10s is a key math skill that lays the foundation for many other concepts. It's also a great way to get kids excited about math!


Here are a few tips to help your child master this important skill:

1. Start with the Basics

The first step is to start with the very basics. Review basic addition with your child before beginning to work on adding by 10s. This will ensure that your child understands the concept before moving on to more difficult concepts.

2. Use Manipulatives

The second step is to use manipulatives. Manipulatives are objects that can be used to help children understand abstract concepts. For adding by 10s, have your child use manipulatives such as Unifix cubes or blocks. This will help your child visualize the addition process and make it more concrete.

3. Write it Out

Once you have used manipulative, your next step should be to write it out. Have your child write out the addition equation as they solve it. This will help them see the relationship between the numbers and the answer.

4. Practice, Practice, Practice!

And the very next thing is practice. The best way for your child to learn is through practice. Find creative ways to help your child practice adding by 10s, such as making a game out of it or incorporating it into everyday activities.

5. Try Some Fun Activities

Learning by using fun activities is always fun. Adding by 10s can be made into a game or incorporated into other activities to make it more fun for your child. Try some of these ideas:

- Make a game out of it! Use manipulatives or draw numbers on pieces of paper. Have your child race to see how quickly they can add the numbers by 10s.

- Use everyday objects. Incorporate adding by 10s into your child's everyday life. For example, when driving in the car, have your child look for license plates that add up to 10.

- Get creative with it. Be creative and develop ideas to help your child practice adding by 10s. The more fun they have, the more likely they are to retain the information!

An Example

Now let's try an example. Suppose we start with the number 30. We add 10 to get 40, and then we add ten again to get 50. We continue this way until we reach 90, then stop because the next number would be 100 (greater than our goal of 90). So our final addition problem looks like this:

30 + 10 = 40
40 + 10 = 50
50 + 10 = 60
60 + 10 = 70
70 + 10 = 80
80 + 10 = 90

And the sum of all the numbers we added by 10s is 300.

Wrapping Up

That's all about how to practice adding by 10s. Hopefully, this explanation has clarified how to practice adding by 10s. As you can see, it's a simple but powerful strategy that can be used to solve various addition problems. Give it a try the next time you're working on two-digit addition. With some practice, your child will be a pro at adding by 10s in no time!
