4 EASY Steps to Teach Your First Graders 10 More, 10 Less AND 100 More, 100 Less

Understanding place value is important for first graders.  Learning to add and subtract by 10 (and then later 100) 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 full proof ways to help your students master 10 More 10 Less 100 More 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.
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 AND give students their own mini number grids
I have a giant magnetic 120 number grid on my whiteboard.  Using this as an anchor chart, I model counting by ones and counting by tens starting from any number.

3. As a group, we begin orally figuring out 10 More and 10 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 organized way like this chart below.

5. Who doesn't love coloring? Add a little fun by incorporating color by number activities.
As an extra challenge, I ask students to use some of the same strategies they used to figure out 10 more and 10 less, to then figure out 100 more, 100 less.  I love providing extra practice for my students with math color by code worksheets.

6. End introducing 10 more and 10 less by playing a fun song while children begin working independently.
Who doesn't love Jack Hartmann? My kiddos go crazy for his lyrical upbeat rhyming tune!  Checkout this Jack Hartmann song on YouTube:
