Understanding place value is important for first graders. Learning to add and subtract by ten (and then later one-hundred) can be easy to master if kids understand that only one number changes within the number. Here’s the good news. . . I have some fun foolproof ways to help your students master this important skill. By strategically teaching 10 more and 10 less your students can grasp addition and subtraction concepts and apply them to similar situations – like 100 more and 100 less.
1. Spend a lot of Time Developing Number Sense in Your Students.
In my classroom, we make numbers with manipulatives and base ten blocks. So, we practice reading and writing numbers continually. We do it together as a group but later students do it independently during scrolling time.
2. Post a Giant Number Grid to Help Students Understand 10 More and 10 Less and 100 More and 100 Less
I have a giant magnetic 120 number grid on my whiteboard. Because it’s perfect to use as an anchor chart, I can easily model counting by ones and counting by tens starting from any number. I also give each student their own mini number grid to use as we practice.
3. Begin as a Group Using 10 More and 10 Less and 100 More and 100 Less
We begin orally figuring out ten More and ten Less of a number using the number grid as a reference.
4. Move to White Board or Paper and Pencil
I love presenting activities in a clean and organized way.

5. Who Doesn’t Love Coloring?
I like to add a little fun by incorporating color by number activities. Therefore, as an extra challenge, I ask students to use some of the same strategies they used previously to then figure out 100 more, 100 less. I love providing extra practice for my students with math color-by-code worksheets.

6. Reinforce Concepts by Playing a Fun Song While Children are Working Independently
Who doesn’t love Jack Hartmann? My kiddos go crazy for his lyrical upbeat rhyming tune! Check out this Jack Hartmann song on YouTube:
Wrapping up Ten More and Ten Less and One-Hundred more and One-Hundred Less
Helping your First Graders or Second Graders understand how to add and subtract ten and one-hundred to any number can be tricky. But, it’s an important skill they need to master with confidence!
If you’ve ever noticed your students struggling with adding and subtracting ten and one-hundred, this packet is perfect practice. Because you can use it as morning work, homework, in small group enrichment centers, or even as partner work it’s the perfect print-and-go resource!
First and Second Grade teachers are loving this resource for tackling the 10 More 10 Less 100 More 100 Less! One teacher said, “This was a good print and go I grabbed to use with both a 1st grader to help her understand the ten more / ten less concept through more options for practice. I also used it with a 4th grader functioning on a 1st grade math level. It was a successful endeavor with both students.!
